SMTNet has a video tape and interactive CD ROM on Intrusive Reflow Soldering that you may want to check out. In addition there are some free inspection standards for pin in hole printing, placement and soldering available at http://www.dpmo-monitori

gregp: Our PTH process has not changed in many years. Our products are fairly simple as far as electronics goes and everything gets potted anyways. ~90% of everything we build is single sided TH with ~ 100 solder joints per board. Each board is ~

Hello, I am new in this forum and also new in PCB manufacturing. now we have issued about silver open and short. we can detect this defect after auto check process and its to late to save our PCB. Is there any way to detect silver open or insufficien

Hi Reese, Thanks for the feedback. So you have a fair amount of assemblies that are new designs with 10% through hole parts. Are these parts inserted manually? What is the soldering process?...wave solder?...selective solder? Do these components

Hi J_Dub, thanks for the continued info...Of course selective soldering would be very time consuming for such a through hole assembly...but 18 minutes, wow...didn't realize selective soldering could take that long. I would like to know the approxima

I have been tasked with finding the equipment necessary to fully automate our TH assembly. Currently about 98% is performed manually on stuff lines with the other 2% using a 30 year old axial inserter. I am asking if anyone else has gone down this pa

We process an average of 300 units per batch with spikes to 750, we can sustain about two to three people populating to maintain good quality/throughput. Part placement is broken up equally to reduce operator stress(usually a limit of 5 different pa

Hi Adam...thanks for your follow up comments. The auto inserter in the video is a machine from a time gone by...But quite impressive. Those machines are good for higher volume where high flexibility may not be required. not sure if all of the comp

Thank You Adam...this is the type of input I am looking for. To summarize, you are an OEM that has gone through the process to remove most through hole parts from your assemblies. Those that remain are primarily connectors which may not require lea

your summary is pretty accurate! yeah our justification on the automatic system is long in the pipeline. we would need significant volume even then we could just bump the staff numbers. I can see how you are having troubles with the legacy requirem
