Metal domes are often made into metal dome arrays. However, have you ever considered the advantages of making metal domes into metal dome arrays? Now let me clarify for you.
customized metal domes
Firstly, we can process metal domes into whole piece of metal dome arrays to assembled on PCB directly, there is no need to assemble one by one, thus efficiency is raised;
Secondly, we can cover metal domes with PET sheet to prevent dust;
Best Technology is the professional manufacturer of metal dome, snap dome, metal dome array in China, with different package: in PE bag, Tube, pick & place reel. We can also provide metal dome array assembled on PCB and flex circuits. Whatever type of trip force of metal dome or dome array you need, we can make it happen.
Do you know how to detect double metal dome? We often receive this question from customer, today I want to advise our testing method to you, please kindly check below for details, then you could understand, hope it’s helpful for you.
The principle is: the upper fixture is equipped with a probe with a higher force than the single DOME.The bottom board is PCB, connecting the lead to the computer. During the test, the upper fixture is pressed down and the probe is pressed into the dome center. If there is a single DOME, the probe will press the DOME down to the PCB and conduct it. The computer shows PASS.If double DOME, the pressure of the probe cannot press down DOME, then the PCB cannot conduct, the computer shows NG;The force of the probe is generally about 1.2~1.5 times, such as 160g of metal dome and 200~250g of probe. This fixture should be used with the electric measuring machine, and the sole fixture cannot be used. If you has assembled the metal dome and tested it again, in case of NG, it should be removed again. Therefore, it is not recommended to test the finished product.
In the previous article (what’s the difference between SUS301 and SUS 304 ), we have a brief introduction about SUS301 and SUS304, the stainless steel materials used in metal dome, which may not be specific enough. Now, let’s use some specific data to deepen the performance between the two material.
1?Material propertiesbetween SUS 301 and SUS 304
SUS301: Suitable for elastic use, high carbon content, high hardness, not easy to elastic fatigue, poor ductility, not easy to stretch.
SUS 301 stainless steel
SUS304: Not suitable for elastic use, low carbon content, low hardness (soft)
Notes:
If the hardness of the two is close, for example (SUS301 3 / 4H and SUS 304 H), although the hardness is the same, but when they are used in elastic products, SUS 304 H is more likely to produce elastic fatigue.
The thickness of the material affects the hardness tolerance (the thicker the material, the greater the tolerance)

Some customers always ask the differences of SUS301 and SUS304, they will ask the raw material of our metal domes, why you don’t use SUS304? Can you use SUS304 to make this metal dome?
Today I conclude these questions, please see below article. Best Technology specialize in manufacture metal domes for a long time, a little understanding of the properties of these materials, so list the differences between SUS301 and SUS304.
Both are belong to Martensitic stainless steel, but has slightly different, The main is that the content of Cr and other elements is different, so the performance is different. Now the material that to use produce metal domes, mainly use SUS301 in the domestic, however more use SUS304 in HongKong, and use both in aboard. everyone will choose the most suitable for the factory processing technology, the ability of the material, the use of different technologies, so that it will achieve the desired best effect: life, click feeling, etc.
SUS304 (stainless steel): it is the most widely used stainless steel. Because it contains Ni, it is more corrosion-resistant and heat-resistant than Cr steel, and has low-temperature strength, so its mechanical properties are very good, and its work hardening is very large. It is not hardened after heating treatment, non-magnetic, with good strength and less elasticity. It is often used with a thickness of 0.4t ~ 1.0T.
SUS301 (stainless steel): Cr (chromium) composition is lower than SUS304, corrosion resistance is poor, but cold working can get a very high degree of tension and hardness, its characteristics are widely used, because of the good elasticity, so at present, notebook is widely used in anti EMI, as the elastic contact part, but often used in thickness 0.4T ~ 0.07T.

Circle metal domes look exactly like they sound, these are sometimes called round metal domes or circle tactile domes. Circle domes work great in applications that require a low profile switch under a membrane overlay. Circle domes can have longer life cycles than triangle domes, but relatively the same cost. The typical size of a circle dome is from 3mm to 20mm in diameter and the range of force is usually 100-60 gf.
circle metal domes
The next type of dome is the four-leg metal dome, sometimes called cross metal dome. These domes were designed specifically for use where traces of positive and negatives can be designed under the dome on the same side of the circuit. Four-leg domes have a better clicking feel than circle domes and oblong domes. Circle domes typically have longer life cycles than triangle domes averaging approximately >= 1 million actuations. Four-leg domes are the tallest of the domes and are not to be used in low-profile applications. Generally Four-leg domes come in a 5mm-20mm range of size, and a 125-500 gf range of force.
Triangle domes are usually used in applications that require a good click feeling but are limited space wise. These domes are also used in applications that require large activation forces, as triangle domes can range up to 6,000 gf. Triangle domes typically also come with legs, which allow them to be mounted to the circuit board without the use of adhesive. This allows the triangle domes to be used in high-temperature applications, where the adhesive would otherwise cause a unit to fail. Triangle domes typically have a 5mm-13mm range of size.
Global demand for supplies used by our customers to treat and help protect people, such as respirators, is currently exceeding supply. Best Technology expects demand for respirators to outpace supply for the foreseeable future.

Q: What can other countries learn from the way China has approached COVID-19?
A: Social distancing is the essential strategy for the control of any infectious diseases, especially if they are respiratory infections. First, we used “non-pharmaceutical strategies”, because you don’t have any specific inhibitors or drugs and you don’t have any vaccines. Second, you have to make sure you isolate any cases. Third, close contacts should be in quarantine: We spend a lot of time trying to find all these close contacts, and to make sure they are quarantined and isolated. Fourth, suspend public gatherings. Fifth, restrict movement, which is why you have a lockdown, the cordon sanitaire in French.
Q: The lockdown in China began on 23 January in Wuhan and was expanded to neighboring cities in Hubei province. Other provinces in China had less restrictive shutdowns. How was all of this coordinated, and how important were the “supervisors” overseeing the efforts in neighborhoods?
A: You have to have understanding and consensus. For that you need very strong leadership, at the local and national level. You need a supervisor and coordinator working with the public very closely. Supervisors need to know who the close contacts are, who the suspected cases are. The supervisors in the community must be very alert. They are key.
Q: What mistakes are other countries making?
A: The big mistake in the U.S. and Europe is that people aren’t wearing masks. This virus is transmitted by droplets and close contact. Droplets play a very important role—you’ve got to wear a mask, because when you speak, there are always droplets coming out of your mouth. Many people have asymptomatic or presymptomatic infections. If they are wearing face masks, it can prevent droplets that carry the virus from escaping and infecting others.
wear mask
Q: What about other control measures? China has made aggressive use of thermometers at the entrances to stores, buildings, and public transportation stations, for instance.
A: Yes. Anywhere you go inside in China, there are thermometers. You have to try to take people’s temperatures as often as you can to make sure that whoever has a high fever stays out.
And a really important outstanding question is how stable this virus is in the environment. Because it’s an enveloped virus, people think it’s fragile and particularly sensitive to surface temperature or humidity. But from both U.S. results and Chinese studies, it looks like it’s very resistant to destruction on some surfaces. It may be able to survive in many environments. We need to have science-based answers here.
take temperature
Q: People who tested positive in Wuhan but only had mild disease were sent into isolation in large facilities and were not allowed to have visits from family. Is this something other countries should consider?
A: Infected people must be isolated. That should happen everywhere. You can only control COVID-19 if you can remove the source of the infection. This is why we built module hospitals and transformed stadiums into hospitals.
We know it’s difficult for most of people around the word to find protection devices, such as face mask, Non-surgical isolation gown , Medical gowns, protective coveralls, Surgical Cap, Surgical Dress, Medical gloves, Safety Goggles, Surgical Helmet, infrared thermometers, please contact our sales, we will be glad to support you.
China’s fight against COVID-19 epidemic has achieved victory at this stage. Infected patients were found in 337 cities in China but now only 28 cities remaining patients in cure. So far till March 31st, there were 82545 confirmed cases in China, while 76225 cured and only 3006 remaining now. Most importantly, many of the areas finds only one figure number increase and others stop increasing for quite some days. If the first half of COVID-19 fighting is inside China national territory, the second half will be on the international stages while noticeable growth on COVID-19 infected cases are spreading all over the world now.
corona virus updates
Best Technology has been collecting the measures in China on epidemic controls so in order to provide a more objective and useful reference for overseas professionals which we hope they could refer to and protect better themselves from the COVID-19.
Governmental Measures
During the height of the outbreak, trains didn’t stop at the disease’s epicenter, Wuhan
Wuhan trains
Trains, as well as other tightly packed forms of transportation, can serve as vectors of illness. The more people, the more closely packed, and the more poorly ventilated the space, you can imagine that’s a bad situation because there are a ton of people, they’re in very close quarters, and they’re a totally captive audience. Cutting off transportation was considered on the top three measures to contain the spread of the virus.
China built new hospitals in a rush, with workers toiling night and day to get them done.
China Newly-built Hospitals
China built two new 1,000-1,300-bed hospitals to fight the corona virus, one created in six days, and the second in 15 days, using prefabricated modules.
Corona virus testing was easily accessible and free
Corona virus testing
In China, patients who were confirmed to have the corona virus were either sent to an isolation center or hospital. The government also made clear that testing for the new virus was free, and COVID-19-related charges that weren’t covered by a person’s insurance would be paid for by the government.
The country implemented large-scale contact tracing in the early 2000s
Contact tracing
During the SARS outbreak in 2002-2003, China set up large-scale surveillance systems that included contact tracing, a front-line public-health strategy that involves identifying and following up with people who may have come into contact with an infected person.
The country postponed non-urgent medical care and moved many doctor’s visits online. Not all patients were given the critical care they needed during the outbreak, though
Doctor’s online visit
In China, elective surgeries and other non-critical doctors’ visits were delayed, and many medical services were moved online. Someone in one place said 50% of their consultations are now done online; they just moved a whole bunch of what was normally done physically online to be able to keep the regular health services going.
Centers for Disease Control exploring a way of therapeutic plan combing Traditional Chinese medicines and Western medicines.
Traditional Chinese medicines treatment
The combination of Traditional Chinese medicines and Western medicines had been proven effective on the SARS fights. Doctors of traditional Chinese medicines had volunteered for consulting and participating into the virus fights.
China used technology that aims to trace every single COVID-19 case
Civilian Measures
Traditional epidemic prevention manufacturers speed up and similar production lines integrating to make more necessary products
mask production line
Many medicinal and pharmaceutical substances manufacturers launched automation assemble lines and increase manpower to speed up the mass production of necessary drugs, masks, ventilators to meet the huge consumption during virus fighting. Many of these companies arranged 24-hour shifts for maximizing the production.
Meanwhile other manufactures such as automotive OEM had change their assemble line into masks productions machines.
At the blast of COVID-19, returning Chinese carrying back epidemic products from overseas as much as they can
epidemic products brought by overseas Chinese
Returning travelers carried extra masks on their flights back to China and donated them to the hospital and governments in need. Some overseas Chinese unions also had helped ordering these products and sending to China.
Chinese citizens did their part to curb the disease’s trajectory on an individual level, too, though we may never know the true scale of their complaints or sacrifices in this outbreak.
China’s road
In contrast to reports in the US of people clamoring over the last hand-sanitizer, the attitude of people in China was that they were all in this together. People stay at home for self-quarantine, lockdown and response to the postpone returning to work and school.
People who thought they might have the corona virus could go to one of the nation’s many fever clinics
fever clinics
People who thought they had the novel corona virus in China would often be sent to a special fever clinic, which have been widespread since the country dealt with an aggressive SARS outbreak in 2002. Their temperature would be taken, and they’d discuss their symptoms, medical history, travel history, and any prior contact with anyone infected with a doctor.
If necessary, patients might receive a CT scan, which is one way to do an initial screening for COVID-19. Each machine did maybe 200 a day. 5-10 minutes/scan. A typical hospital in the West does one or two an hour.
People quickly shifted jobs in order to assist during the outbreak
volunteers
When it came to the non-medical response, there was a nationwide sense of solidarity with Hubei. Other provinces sent 40,000 medical workers to the center of the outbreak, many of whom were volunteers.
Workers in transportation, agriculture, and clerical positions were encouraged to new positions such as delivery, courier and epidemic prevention manufacturing, too.
While staying home, it’s been relatively easy for Chinese people to get extra food and supplies
Enough food
China essentially mandated a country-wide shut down, demanding that every Chinese resident stay home until the curve was flattened. But in West, unlike China, a country-wide shutdown would be difficult to enforce.
Fifteen million people had to order food online. It was delivered. Yes, there were some screw-ups. But few said: every now and again there’s something missing from a package, but food supply is pretty much normal via ordering online.
If you would like to know trip force, rebound/return force, and travel of metal dome, a metal dome inspection instrument-load curve measuring instrument is required.
circle metal domes
Load curve measuring instrument is a very important quality inspection tool. Generally, we will inspect trip force of metal dome before delivery to guarantee quality. The load curve measuring instrument uses a high-precision force sensor to sense the change of the trip force of metal dome, and obtains a completely accurate load curve by computer processing, then prints out data such as trip force, rebound/return force, travel and so on.
