| I am looking for clip art images of electronics assembly. Images like wave soldering, surface mount components, soldering irons... just general assembly graphics. Many sites have different individual images that they use I was just wondering if a

| Has any anyone established / published quality standards for BGA solder joints? Is IPC-A-610 in process of adding standards for BGAs? | The debate continues. I have felt for some time a maximum 20% voiding is allowable under certain conditions (w

Good day, or night to all, I'm new to the industry and I'm looking for some good source material to start my career in SMT. This forum is fantastic and your previous links are all very useful. However, if you don't mind re-iterating, can you pleas

As Steve said there should not be a problem with cracking plastic components but if you are reaching 180c there will be a problem with secondary reflow on the top side of the board. PCBs flex during wave soldering as they do during reflow if not supp

You will have to forget about the idea of finding ONE algorithm to optimize SMT placement. For pick and place, collect and place, turret type "chip shooters" with moving feeder cartridge and moving board you will each have to find your own algorithm

I have a used Hollis machine that might suit your needs. The only problem is that it is an oil blanketed machine. It is a 7" Hollis Nova 175. Right now it is collecting dust. | | | | | | | | | | Is anyone aware of any papers/publications dealing

Good Morning everyone. Per repeated suggestions I have been reading back issues of SMT and Circuits Assembly magazines. I have just read an article concerning selective wave soldering which I understand is to be used when active SMTcomponents are a

First, determine a standard to follow. IPC/EIA J-STD-001C "Requirements for Soldered Electrical and Electronic Assemblies" is most current for electronic assemblies. Second, by your customers spec. determine which class of the standard to apply. Use
