Hi John, It depends on what equipment and resources you have at your disposal - if you have an antique wave with crap adjustment & hand sprayed flux, no debridging/air knife system on a tightly packed board with a multitude of fine pitch connectors

hi, there is an IPC standard, IPC-A-610 - Acceptability of Electronic Assemblies. According to this manual, solder in the bends of a lead does not matter, but solder touching the body of a component is a defect. I cannot find a specific reference in

After an in depth examination, I found that the problem was not a defective connector as I thought in the first place. Actually is a broken through-hole on the Quad Align sensor. I requested a spare part to PPM. Mr. Bobpan, thank you again.

Hi Aurther, Thanks for a prompt reply. I agree but unfortunately our AOI is 2D and misses a lot of solder defects especially on connector terminals which are surface mount. We are also dependent on operator at AOI to mark the defect if caught by AOI

I'm curious why would you have a solder defect on a connector like the one you show, even if you were putting it down with tweezers. If you are getting lots of such defects, its really not inspection you should be looking at, its the cause.

This one's got me stumped, so I thought I'd throw it out for discussion: I have a 20 pin SMT ribbon connector by Molex that I've been using for about a year without problem, but recently things aren't looking so good. The solder is pulled up off of

We process a double-side reflow board (10 ups). Chips and IC's on the bottom side while chips, IC's plus thru-hole connectors and IC sockets on top side (bottom side first then top side reflow). In the past, we were not encountering any soldering pro

In production,we are seeing high defect for Hair Line Solder Shorts for PTH connector and the Hair Line is too tiny that X-Ray and ICT could not detect.Any suggestion on how we can resolve or at least detect this upfront.

I am looking for defect rates on hand soldering. Specifically - I have a large number of wire jumpers that need to be hand soldered across two boards (connectors are not an option). I am looking for a defect rate so I can perform a cost analysis in
