Metal Dome in Tube

Monday, September 26th, 2011

Regarding the Four-leg metal domes, for small-medium volume production,
if people want a high assembly speed, but don’t have Automated SMT machine, we recommend us our metal dome in tube, as well as Peel & Place dome. And here,  I’d like to say more words about metal dome in tube. Next article we will discuss another.

To use metal dome in tube, you must have a dome placement pen, or auto-pick-gun. You insert the tube into that device, then move the device above the place where you want to place a metal dome, then push a button, a dome will come out, to fall on that position.

Using tube dome, you only need to push the button to place the metal dome, and don’t need to pick a dome by a tweezers, so it’ll make dome placing become a easy job. You can put about 1,000-2,000 pcs per hour. In fact, some expert guy can reach up to 3,000 pcs, 5,000 pcs or more.

Also if you can send back the empty tube to us, we will give you some discount, but in most case, oversea customers will not do that, because shipping fee is more expensive than tube itself. But I think if some days later, the cost of tube increased and shipping cost lower down, people will consider to re-use them, in a green way. Just make sure the tube is clear, fresh from any dirt, dust.

All right, leave comments if you like this, or have some comments, or better idea to improve the tube metal dome.

Tape & Reel Metal Dome – On Sales

Monday, September 26th, 2011

After more than one year R&D, we are going to release our new Tape and Reel metal dome, a new packing method of metal dome which is suitable for automated SMT machine.

Each metal dome is sealed in a socket on a continued tape and packed on a reel, so it can be picked and place like normal components such as resistor, capitor, on SMT machine. Metal dome packed in this way named as “Tape & Reel Metal Dome” Also someone name it as “Pick & place metal dome”.

Please note even this metal dome is used in SMT machine, we don’t recommend to solder them like normal components.

Now we provide 8.4mm, 12.2mm  Four-leg metal dome in this packing. 5,000 pcs and 4,000 pcs each reel, respectively. We will give you some discount if you  order them in Sep and Oct. It’ll save a lot of your assembly time and money!

Four-Leg Dome with Legs

Tuesday, July 5th, 2011

As we know, there’re already four legs for our Four-leg series metal dome, and this is why it named four-leg dome, or cross metal dome. So what do you means “four-leg dome with legs”?

Let me firstly see the looking of a normal four-leg  (Cross) metal dome.

Normal four leg metal dome

We can see there’s no extra legs except these four legs which will be put on contact PAD of PCB, FPC, or membrane.

As we don’t recommend soldering metal domes on the board, so how do I adhere the dome, except normal “dome array“, “single key dome array“, or in the socket? Can I fix it on like triangle metal dome using two legs insert into the board hole? That’s the reason whey there’re extra legs for F series (cross) dome. You can see pictures.

Now is everything clear? There’re two extra leg, and you can insert the into the holes of board like triangle metal dome do. Currently on our Dia 11.4mm four-leg dome, these extra legs length is 1.2mm and width 0.9mm.

If you need more information about this special four-leg (Cross) dome with legs, contact BEST and we will give details to you. We can also make new tooling to make new diameter four-leg metal domes.

We succeeded to develop the new one million life 10mm four-leg metal domes lately.

Saturday, December 19th, 2009

There is a very imprtant & good news for all of us. Following up with the development of the one million life times 6mm, 8.4mm, 12.2mm four-leg metal domes/snap domes by Our R & D staff, we have won our customers further trust by the quality, price and service. Including some very famous brand, such as: Emerson, Honeywell, Sigmatron, Dyson etc..  They continue their efforts, follow with the need of marketing, & developed the 10mm cross shape metal domes with one million life times lately.

The specifications of this type are similar to foreign famous brand, such Snaptron, Nicomatic, but the price is lower 50% than theirs. We have the 220gf, 280gf, 350gf for this type, with or without dimple & Stainless Steel or Nickel Plating are available.

10mm diameter metal dome

It is almost the blank state for this type with one million life times in China mainland marketing. Our lunch of this type will fill in this blank state, & further improve our four-leg shape metal domes series.

Our company has the diameter from 6mm to 20mm four-leg shape metal domes now. You can find all of your required from here. It also consolidate our company is the leader manufacturer of metal domes & metal dome arrays in China mainland.

Four Legs Metal Dome New Trend

Monday, March 16th, 2009

On every weekend, we will have a short meeting to check the statistics data of that week and we found out a very obvious trend in the shipment of our Four legs series metal domes, that is: “more smaller size, more high quality requirements, more packing methods”.

There’s a one time, when membrane switches were so hot in the market, the dome used in it was big diameter one such as 12.2mm, 8.4mm etc, and the force were 220gf, 280gf, and 320gf. As the touchscreen technology become popular, it seemed that few and few company used tactile metal domes, all of the guys turn to try the new tech.

In some important section, however, the vital switch have to be avoided of mis-handling by human hand or an incident, and touch screen cannot reach that goal, so tactile dome turn back to the top of desk. As people have gone through the experience of tactile dome and touch screen, they want to strike the right balance. Such being the case, some company designed the dome with smaller diameter with lower force but remain good click feeling, and Four legs series metal domes are the right choice for them.

With its unique structure, Four legs series metal domes can have the best click feeling, and at the same time, we have add several supporting circle in our tooling so that there’re related circles, visible and unvisible, in our goods, to make sure high quality and long life cycles (over 1 million times). Four legs metal domes

There’s a common sense that “the smaller diameter dome is, the more difficult manufacturing will be”. With our special design, our 6mm and 7mm Four legs series metal domes have endure strict testing by our clients. Recently, we have becomed the supplier of metal dome for Emerson. We wish more customers can try our new small size metal domes, and to meet your various requirements.

In next article, we will discuss the requirement of packing method for Four legs series metal domes.

Brand-new Four-leg Domes in 8mm

Saturday, November 15th, 2008

Hi, dear friends! Rory here would bring you a brand-new diameter of our four-leg domes, it is in 8mm! Just follow me, I will show you the parameters of them!

Normally, the diameter of  four-leg domes are 6mm, 7mm, 8.4(8.4mm), 10mm, 12.2mm, 16mm, 20mm, none use 8mm. In fact, in most of cased, this 8mm dome can be replaced by 8.4mm, but sometimes, customers like to use exact 8mm. This is why we develop new mould for 8mm dome.

So do not hesitate to contact us if you need our products or have other questions!

Best Technology, providing best products with best service in best price, would always be around you!
