Hi Daan, What we did in the time was pareto analyses on all board designs to determine the critical areas (mainly design errors) and only inspect those specific problem areas. Every batch had a copy of the PC board with problem areas marked and only

I have a question about inspection, touch-up, and how far you need to go to get a product that meets the required IPC-spec. According to some reports (i.e. "New Study Reveals Component Defect Levels" by Stig Oresjo of Agilent) the average defect leve

My 2 cents... Screen printing may very well have a leg up on deciding SMT defects... however if you pay attention to your stencil (aperture size ratio etc..) and inspect your prints... I believe its a much lesser number... (paste MFG also plays a ro

When using X-ray to inspect BGAs, what different types of defects are found, and where in the production process does each type of defect tend to occur?

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
