This is a similar question to https://smtnet.com/Forums/index.cfm?Thread_ID=22578 but I didn't want to steal their thread. In the recent COVID-19 events, I guess that some US companies are going to think to relocate their PCBA work from Asia / China

Thanks for your thoughts. So it seems then that the temperatures that we're seeing aren't unusual, and just need to sort out the fan issue... @Sr. Tech: Yeah, totally understand the radiator effect. Once the fan issue is sorted, we plan on insulatin

Why those 3, are they used? (as I don't think a 680 is a current model) From what has been said previously on here, ESE Sell a highly regarded printer that matches the big boys on features and crushes them on price. SJIT is a high end printer, I un

+1 to what Sr. Tech said. I'd also add that you could have some uneven deterioration of the centering jaws. Check by doing a couple of things (this will help check if the tool/tip is bent/deteriorated as well): 1. Turn off mechanical centering, and

Yes, we can't use pure Pb PROCESS. And as I say we will not use it anyway, as we have lead-free BGA's, LGAs, component with Solder Charged Terminations... It's became almost normal practice to solder it with leaded solder pastes. In this case peak re

YES there is an IPC target/acceptable spec In general terms the barrel thickness in the hole should be 1 mil (thou). IPC has an allowable limit lower around .75 with some other factors. I have been checking barrel plating on all incoming boards since

OP here Everything you have said makes sense. However, sanity check me on this. The one thing that IPC-A-600 does not discussion is inspection sampling or frequency, which is discussed in section 4 of IPC-6012. Table 4-3 lists all these different

The my700 can dispense 1 million dots per hour. It's not an exaggeration either. It literally never stops moving, and is dispensing without contacting the board. It uses the same type of mathematical calculations that a plane dropping a bomb uses in

Is below the correct interpretation of IPC 610/JSTD requirements for FLAT LUG LEADS (seen on USBs and Diodes mainly) For class 1 or 2, no toe wetting would be required as minimum side joint is only 'evident wetting' and no actual length or fillet he

As Tom said, we assign internal P/Ns and list all the "approved sources". If the customer BOM includes their own internal part number, we simply add the Customer Prefix, and use their number. If they don't, we utilize 'CUS-R0001' format. This can be
