In-Circuit test, or ICT, is the most common method of electrical test for an assembled PCB. It is the most comprehensive and accurate method to ensure that both the PWB and components are working to specification. Not all components however can be el

Looking for advice/products on ways to get heat out of a package and into an internal thermal plane. Will have electrically isolated thermal pads (going to an internal thermal plane) under the part. Need a way to get good thermal contact between par

You might consider installing a noise kit as it sounds like you've tried almost everything else. Electrical interference on these machines causes erratic problems, especially as they get older. I would call Speedline tech. and see if they think the

I am looking to apply 10-15�m of a conductive material that will withstand 280�C. Our product consists of an alumina substrate sputtered with NiCr (2000�) and Copper (2000�) and 15-60 �m of electroplated copper (all metals patterned on the substrae)

I have never seen any industry standards for setting up an SMT assembly facility, but I�ll offer some basic advise. An ideal SMT assembly facility is one that is clean and well lit and has environmental controls to maintain temp and RH. Temp of 24C (

We have four pick and place machines all exibiting a residue that seems to build up over time on wiring and electrical components. This residue appears as a white haze on wiring, caps and fuses (these are the components where it is most obvious). Y

By no means clean room but pretty clean environment. We have ultrasonic air humidifiers maintaining our air at about 45 RH. I agree with you about airborne stuff attaching to electro-static. It's a mystery why it is isolated to four machine, thoug
