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.

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 Switch, and so on. It is 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
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.
