And you can see at least a little through them. That can be a slight advantage as well.

Hi, I am having a problem with component position on a flex circuit. It is an eight up panel. The flex circuit is mounted on to a piece of fr4 with presure sensitive adhiesive, this is done out of house. The problem is, I will locate the parts on one

Nothing wrong with using RoHS BGAs except that the spheres won't melt/collapse at normal leaded reflow temps. Reliability will questionable. Some people use a hybrid profile with a slightly higher temp (~230C)and a slightly longer TAL (60 -90 sec).

Vicki: The other responders make good points. Taking a slightly different, slightly more aggressive tact, you might try something like this: * Click on ... http://www.ssafl.com/bat_prod.htm ... and buy a unit of the proper size to fit your stature

As far as aperture dimensions go, I found a technical note written by Micron that recommends using "square apertures with sides equal in length to the diameter of the PCB pad. The corners of the square should also be slightly rounded, and the apertu

Hi Back later on this tread, yet I did want to slightly correct one thing DaveyF wrote. Again only slightly. Even at 90C, moisture does start to leave the board. Now it doesn't do it so well as above 100C at sea level atmospheric pressure, yet it s

We did figure out the issue. The plastic cover inside the LED lighting unit had a slight film covering it, which made the picture slightly hazy. We had to disassemble the LED module to get at it, cleaned it and it was fine. I didn't think this would

OK, you can't glue, Pallet Guys pallets are out the door, dual line reflow prevents from any lower temp solder paste.... Do you have a 3D printer? Are there parts underneath the connector in question? Measure the PCB thickness, pint out a custom hold

Blue rectangle on the screen is actual search area. Green cross points excatly to the component centroid how vision system determined it - so, your component was picked slightly off center but still within the range. Now, the reason for offset can be

A lot of MELF components have solder ends that stand slightly proud of the main body where your vacuum would lift them, so vacuum leaks are most likely the culprit. Upping the Vacuum to the nozzle may help, but better thing would be to modify the noz
