It depends on the flux type. If it's water soluble, it should be cleaned soon after reflow because OA flux remains active after reflow. If it's rosin or no-clean (low-residue), then the only concern is the longer wait time, the more difficult it will

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

Hi you there, Do you have any experience upon the shelf life of PCBA which passed 100 cycles of liquid to liquid thermal stress test, 125 to -35 centigrade for 15 minutes and 5 seconds of transfer time from 125 to -35 centigarde. Will apprecia

Hi, I have a bad experience whenever assembling the PCBA that using SMD film capacitor as I encountered a lot of non wetting and tombstone. I did experiment on my reflow profile and stencil design and the result was improved but not totally solved.

Just for your reference. If you need to check for surface contamination, then we shall go for microscope inspection at different modes. But this will not reflect on actual PCB performance. Solderability test will still a good option if PCBA is expe

Hi, We design electronic equipment that ends up in a fairly dirty environment (i.e. lots of dust bunnies, dirt, debris, etc...), and I was wondering if there were any detrimental affects of having no clean residue on our boards. I don't think it wo
