Metal Dome Array Color

Tuesday, April 5th, 2011

There’s color for every thing: Red, Green, Blue and etc. So it is the same for our metal dome array. Currently there’re two basic colors:

1) White

2)   Transparent (Clear)

Of course, there’re other colors, if you print the silver ink (EMI), or choose rubber dome array, Light Guide Film (LGF), etc. But in this article, we only discuss above two basic colors. Others we will discuss in future.

Here are pictures showing them.

White metal dome array

white double layer dome array

Transparent metal dome array

Transparent four-legs dome array

Maybe you have following questions. In fact, they’re the most common question customer asked us:

A)     Why color different

B)      How to choose the suitable color of metal dome array

In order to answer this question, let me look back the structure of our metal dome array. You can see this blog “The whole thickness of our metal dome arrays” for more details.

 

As you can see, there’re two basic structures: Single layer and double layer, but both of them has the same Mylar layer. And the color of this Mylar is the same as Transparent (Clear), so to color of whole dome array is depending upon the color of Spacer.

For Single layer dome array, because there’s no Space layer, so color is upon on Mylar;

For double layer dome array, if Spacer is white, then whole product looks white; and if it’s transparent, then whole dome array like clear.

 

I think this is easily to understand. Isn’t it? So let’s go ahead with question #B “How to choose the suitable color of metal dome array?”

Here’re some basic principles:

—To choose White dome array, after assemble on PCB, you can not see anything from the PCB except where cutout on dome array, like below picture:

white dome array on pcb

So if you

a) Need to cover PCB and components on it; or

b) Need light cover or light reflect; or

c) Cosmetic requirements such as the keep environment harmonically; or

d) Other special requirements

 

—To choose Transparent (Clear) dome array, even assemble on PCB, you can still see the PCB, so if you

a) Want a see PCB in assembly process to adjust dome array location, for a easily consignment; or

b) No requirements to cover PCB and components on it; or

c) No light cover request

d) Other special requirements

Now I think everybody should be clear for color of metal dome array. Am I right? Leave a message or write email to us if you have comments, ideas, or question for dome array.

Light Diffuser Material and Function in Light Guide Film Dome Array

Tuesday, February 15th, 2011

Low-carbon, environment protection is widely considered in production design and daily life. Use a Light Guide Film (LGF) in your dome array will save LED quantity to save power consumption. This is why in recently years most of metal dome array in your cell phone will use LGF.

As most of LED viewing angle is 100-150 Degree and limited to light irradiation rang, even there’re light on the whole dome array area, but the light will be focused on certain area, the area around LED is more bright than other area. You can see from below picture.

So you need to have a extra tooling to diffuse the light to make the it more well-distributed, then a light diffuser is very useful in that situation. Or you can call it “light masking paper”.

You can see this picture showing there’s a piece of light diffuser above each LED and the light irradiation is much better now.

Oooh, you will say “So great”. Maybe you want to know what is made from. In fact, it’s very simple. It is a kind of single sided adhesive peel-off tape with two different colors on top and bottom sides.

The side with adhesive which stick on dome array is white (white is a good reflector), and another side is black (black will not disturb or affect the light irradiation). Here are pictures of them.

Top Side

Bottom Side

Light diffuser bottom view

The raw material of this light diffuser is a whole sheet so you need to divide it into several small pieces with the size you need. You just peel-off one small of them and put on LED with light press, it’ll be stick firmly on light guide film of dome array. Very easily!

Normally we will not provide the light diffuser along with the LGF, so if you need them, please talk with us when you order LGF dome array with us and we will do it for you.

Leave a message if you agree with me, or have some comments.:-)

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!

Newly Advanced Laser Machine for Dome Array

Hey, everyone! It has 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 are going to introduce our newly advanced technology of laser cutting, so that it is 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 do not have laser machines, it is difficult for us to accept a dome array order of small quantity (like 1K or 5k) without setting up a tooling! Sometimes, customers do not 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:

Laser Cutting Machine

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.
