We are in the watch & clock Business. We have a Watch IC chip that has to be wirebonded using Ultrasonic aluminium wedge bonder. The wire dia is 1.25mil. The PCB is made of G10 Glass epoxy copper clad laminate. The copper thickness is 18 microns. The

I've seen some glass melf's fall off in our facility due to the glue not adhering to the body very well. You could pick these off with your finger after they had cured. (With little or no effort - I never bothered to actually measure the force requir

I've mounted the $%&R$#$&%$(&! pain in the neck shield clips in the past. (Excuse the simulated profanity- I couldn't help myself.) What we went to was a frame & shield combination. (The frames are cast & then plated w/tin. We have used both plastic

1. SRT has been recently calibrated - problem is too many hands in the machine and careless mistakes. The profile is good and has been recently checked by a fellow from Genrad. 2. We are relying on the left over solder from the previous joint and

This will probably sound like a dumb question, but... I have a specific 1206 chip resistor that routinely ends up placed upside down on the pcb. We use Juki 750 placement machines. I normally run the machine with the auto-correct for the pick posi

IPC-D-356 is a data transfer language developed by the IPC to replace Gerber. It is a far more intelligent form of physical definition for PCB/PWB. The only segment of the language that seems to have developed any market support is the physical netl

I agree with EMC based on what you described, and they build good pallets along with a few others, a small word of caution is that pallets are bit expensive typically several hundred dollars or more each. So if you find that is the road you go, be s

Thanks for the info on the printers. I have printed conductive epoxy on Dek 265 with great success in the past. The issue I have is that I need to attach with both epoxy and solder on the same side of the PCB. I could double print. Print conductiv

Hi Brian, yes that�s possible due to the presence of Au in the joint but nothing to worry if the Ni/Au is done properly (means not to much Au in your plating). "rugged" I haven�t noticed yet, that may depend on the definition and maybe the magnifica

Your broad question will bring many answers.You do not mention PCB type which plays a key part in the inspection specs you look for. Your question is like asking "What is the best automobile?" You will have 1,000,000 answers. Best answered this way:
