Hi Guys, Can you give me a good bird's eye view in Verifying First Off via ICT Test. We currently verify our first off via naked eye for just the solder joint quality, orientation of parts etc. Aside from open and shorts, what can ICT verify? how c

Have you considered mounting this component after the assembly has been washed. Then, mounting the component and cleaning its solder joints individually. Alternatively, have you considered using alternative cleaning solutions to a saponifier (and a

Hi, Has anyone done this? X-ray a populated PCB and found voids on chips and some IC solder joints? Is this kind of screening acceptable? I got a PCB with this problem and not ruling out paste, profile and contamination issues. Please Help as it see

Dreamsniper, We would need much more details about your process to help you to determine the source of voids. Type of paste, how long you leave your paste on stencil, your relative humidity, reflow profile, type of oven, oven environment (N2?) and so

Ya Russ is right for Ti Parts they tend to use more pelladium, which requires a bit more heat average temp increase is about 10 degrees C. from 225-235. As far as optimum solder joint I look for fillets on all sides of leads. The back of the lead is

Hi Frank, What are your main issues on inspection? Is it missing or missaligned components, poor solder joints, or long inspection times? If it's a good system that does everything you could start it after the printer to verify that operation, the

Or leave it stand alone. Granted, you may not be able to inspect 100%, but you can inspect before relow, after relow (if your AOI does solder joint inspection), inspect before wave and afterwards if needed. Now how did you justify a peice of equi

HI, Can anyone recommend good AOI which is able to inspect solder joints, We fix on ROBOTECH, OMRON and AGILENT. Have anyone expirience with some of them. For example OROBOTECH offer us machine with 13 cameras, but this sounds me like: waste

I am a contract Mfgr. and we receive these designs quite frequently. ENIG is the finish and the designs do utilize pushbutton switches from membranes. I am not provvy to any reliability or performance data but we process alot of these designs. If

I have seen good results on OmniFlo 5 for Pb Free solderpastes PROVIDED the boards are low to medium thermal mass and have no high conveyor speed (high production) requirements. Max peak temp you can set on O5 is 280C, enough to get 230C on-board tem
