Hello to all interested parties, I am a doctoral candidate looking for participants in a survey about supply chain efficiency based on communication. Particularly I am interested in people in the PCBA (Printed Circuit Board assembly) industry in manu

Hi Gani, HASL is normally very good for solderability providing there is a good consistent coating of HASL on the pcb pad. But it is not unusual to have a very thin coating of HASL on the pad and this is poor for solderability. You then have tin/copp

Obviously a totally clean floor is the best. So what if you have 1 particle of dust on your entire production floor? Is that 1 part per million (1 PPM)? or is that 1 part per billion? or 1 part per ???? How do you measure dust and come up with a

I do not know what software version you have, but on older versions it is best to have a mounting inspector set to be the primary and then mask out all labels and solder so it just locates the part. Then add another mounting inspector for looking at

Dear Gabe, Once you have the mount data in the program, you can move the camera automatically to the location by tracing each location one by one. If I remember it correctly it is done by having the location highlighted in the program and then by pr

You can contact IDI directly. Also try QA, they are a little cheaper in price. .050 center probes are not uncommon and should work for your application. Both may have a minimum order of 200 pieces or so. I don't know what Mouser's minimum order a

Where you inspect depends on what you're looking for. X-Ray is a fairly specialized piece of gear and doesn't lend itself for example to paste registration or thickness measurement. A laser system is better suited. An X-Ray system would allow you to

Clearly you are above liquidus for too long so you can either increase conveyor speed or lower some zone settings. With your current recipe you don't mention the conveyor speed or the total profile length. Also ...are your max / min slopes really so

We have Mydata and you can print a report telling you the average placement time per part number. I monitored a few months of jobs, broke things into package type, grouped packages with similiar times (such as chip components up to 1206, SO-8,14,16

Thank you for good answers. The Evest EM-780L machine that I linked to further up has a IPC-9850 at 25000 so if I get half I might be able to get the work done. How many people do you have working on the SMT line? Do you have all you're machines in
