The whole thickness of our metal dome arrays.

Saturday, November 7th, 2009

This time follow me to see the whole thickness of our metal dome array products. We have two types of the metal dome arrays: Single layer & Double layers. Please see the following structure:
  Single layer metal dome array

 Double layers metal dome array

1.For the Single layer structure: the whole thickness is equal to the thickness of the Mylar & metal dome. Normally the thickness of Mylar is 0.05mm.

2. For the Double layers structure: the whole thickness is the same as the Single layer structure. You can see from the picture, it is the double layers, but the spacer is parallel to the metal dome. So that you can ignore its thickness. Normally the thickness of the spacer is 0.075mm.

If there is enough space between your PCB & cover layer by the side of your button, It means over the thickness of the Mylar & Spacer (0.05+0.075=0.125mm), we recommend you to use the most popular double layers structure. Because there have ventilation between the domes, when you press the domes, the air can ran out easily. So it will be better with click feeling.

I think you are fully understand the advantage & disadvantage of the two structures now. For more information, please feel free to contact Best Technology.

IQC For Metal Domes

Thursday, October 15th, 2009

Recently, I have found there are so many different names regarding the metal dome. “metal dome”, which we normally called, some called “Snap Dome”, “Tactile Dome”, and “Dome Switches”, and so on. It’s a very interesting phenomenon.
I have checked there is a question everyone should be very concerned about this issue. So I have posted the content of my answer as below, I hope to be helpful for all of you.

A guy in BBS asked “How to solve the following problem?”
1.      What should we pay more attention about the quality of the metal domes?
2.      How can we check?
 ——– The following is my answer.

 Simply speaking, for your IQC department to check the metal domes, they need to note the following points:

 1). Shape (clean, dirt, dust, grease stains & deflashing);

 2). Actuation force (test by force gauge machine);

 3). Contact resistance & stability.

 4) You can press the metal dome for several times to check whether the dome can rebound to original position or not. (the process named as “metal dome rebounding”)
If what you make it metal dome sheets, the following should to be known:
 5) Appearance of PET (clean, dirt, grease stains)
 6) Lose or double metal domes
 7) The location of each dome is the same as the drawing of the PCB
  8) If there is EMI printing, pleas take care of the quality of the tracing
 9) Others, such as location holes, out line, and so on.

For more information, please visit our website:

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.

One-Key Dome Array: Single Metal Dome with adhesive PET

Saturday, October 18th, 2008

Hi, welcome to Best Technology again! Last time we have introduced our lacer cutting technology! Further to that advanced technology, we have dealt with many orders of one-key dome arrays, which are difficult to handle before the adoption of laser cutting machine!

Tracing the days when we have adopted the laser cutting machines, we have lost many orders for the one-key dome arrays! On the other hand, we cannot meet to our customer requirements for dealing the single metal dome with adhesive array without setting up a tooling!

As we all know, a set of tooling would cost an amount of tooling fee. Considering the quantity not large enough, as well as price relatively high with tooling fee, many customers refuse to give orders to us. We also felt sorry for not able to serve with our customers and never give up searching the best way to work out this problem!Â

Finally our efforts are paid off! Now we can deal with any order of one-key dome array. The adhesive array size would be a bit larger than the dome size, so that customers can easily stick the single dome onto PCB or any place they want put to.

Followed is one of the drawings for 8.4mm four-leg dome array:

Peeled Off Kiss Cut Metal Dome Array

Peeled Off Kiss Cut Metal Dome Array

Of course we can do any size as per customers requirements! For instance, we have dealt with one case, where our customer demanded limited space for adhesive PET (like 8*8mm) of 6mm circle metal dome.

Usually we would do the PET size of 10*10mm for 6mm domes; in this case, we finally work out by the size of 8*10mm, so that the array would not only surpass the limited space, but also functions well sticking to the board! Hereby are some pictures of goods we have made:

Single Key Four-leg Metal Dome Array

Welcome to any order of One-Key Dome Array from Best Technology! We can make most tapes of metal dome in different size and shape.

Seemed interested? I think it will save a lot of time for you to assemble bulk metal dome using a adhesive tape at your side. This is what we want, to save time and increase efficiency of assembly.

Any question? Please leave your message or contact us todayd for single key metal dome array now!

Hey, everyone! It’s been some time for our last communication! Pls do never forget our best products with best service from our Best Technology! We always dedicate to serving you better, faster, and easier! Today, we’re going to introduce our newly advanced technology of laser cutting, so that it’s available for us to guarantee the manufacture for small quantities of dome array, no matter with single domes or in customer designed, and no tooling fee would be charged! 

As you know, when we don’t have laser machines, it’s difficult for us to accept a dome array order of small quantity (like 1K or 5k) without setting up a tooling! Customers don’t want to set up a tooling, but our manufacture would consume a large amount of hand labor! Thus, many opportunities of cooperation have been passed because of the cost of manufacture! 

Fortunately, we have adopted the technology of laser cutting in making dome arrays since second half of this year! With laser cutting machine, we can handle the outline and key positions of dome arrays without setting up a new tooling. In this case, our customers don’t have to worry about tooling fee for any small order, and we don’t have to worry about the large cost of labor force! Thus we would have more opportunities serving with you. Pls view part of production line as followed: 

  part of laser production line  efficient and accurate  cutting by laser

Welcome your any order of dome array !

New LGF metal Dome Array Announce

Saturday, June 28th, 2008

LGF metal dome array is a new design with the purpose of improving current one. As everyone knows, the light under keypad is coming from the LED on PCB motherboard. We need to put about 8-10 pieces LED on each board, but if the design changed to use LGF, then we can save several LED, as well as SMT fee.

LGF, which full name is Light Guide Film. When we add a LGF on current normal double layer or EMI dome array, it becomes a LGF dome array. It can achieve great result of light distribution.

structure of double layer dome arrays

LGF, at least one surface out of front and rear surfaces of the light guide film is formed with a pattern such that density increases as distanced from a light source to allow light to be uniformly supplied to the keypad, or is concentratively formed with a pattern at a particular region of the light guide film to allow the light to be concentratively supplied to a particular region of the keypad.

You can see from belowing picture of a LGF. You can see the pattern around the light source (LED). Only 9 LED are needed for such a large area (160*72mm).

LGF

On the motherboard of mobile phone, through the optical refraction, only 1~4 pcs LED will be enough for soft and high light luminance, if using our LGF dome array (mobile phone LGF). At the same time, we can adjust luminance of the black area during the design to achieve the value to 30CD/M2.

You can see from this picture, when we turn on the LED and then the light will be guided through whole flat area.

LGF with LED

Our LGF dome array can be used widely in high value added mobile phone, solving the problem of uneven of luminance, high power-consumption, big room space requirements and high costing. We can make LGF dome array in various color and shape, also adjust different artwork to make LGF, such as printing, mould punching, etc.

dome arrays

LGF Dome Array Character:

  1. Good lighting result, even luminance and high intensity of light
  2. Soft, flexibility and elasticity, thickness is about 0.125mm which does not need too much space.
  3. Save LED & power consumption, two LED will be enough for small area mobile phone LGF.
  4. No special request for electrical trace
  5. Great stability, long durability, the life cycles can reach up to 1 million times.
  6. When assembly with metal dome array, LGF will not affect the clicking feeling.

Please contact Best Technology for more information about LGF dome array. We are always to be your best partner of metal dome and metal dome array around the word.

Different Request of Metal Domes

Monday, December 4th, 2006

Although we have to say that one product should be have the same standard so that it can be used in everyway, we don’t need to worry about who made it. That “standardize” and “internationalize” is good thing for today industry develpment. Bbecause of different culture background, however, there’s still some differences between them.

For normal person, the stardand metal dome are acceptable and will be satisfactory. But what they concerning about is various. Under the NDA with our client, we can’t release more information about them, but we can list some simples phenomenon: Some clients concern about the surfacing plating; someone larg or small dimples; diameter of interior round is the important things for few clients whom worry about the contact area; width of feet is critial elements in some customers’ end-products, and so on.

Everyday, each time we get enquiries about metal dome or sometimes named as “metal snap dome“, we’ll find some difference, whether it’s small or big, we will try to do our best to meet their requests, and feel very happy when problems are fixed and customers found out what they need. At the same time, it’s also a funny time to challenge new affairs. As the preverbs says: “There’s no limit to knowledge”. We appreciate such kind of differences.
