Instead of you spend money on AOI,my recomendation will be to install SPI machine ( solder paste inspection machine)since most of your defect are solderability issues.AOI only will ensure no escapee to backend/human escapee but SPI will help to to en

Is there any official or in-official in-house standard for ICT pin maintenance on volume boards? Like, how many test can or should one pin do? Currently we just change when we get contact problems. That probably after 5000 tests or so. But I guess
