Hello, since some days we are facing strange problem with SMT component reflow paste on one side of the component is reflowed correctly while the other side is 10%-70% non-reflowed (same component on 3 positions per module, alwyas the same land pad)

hello, we are profiling with the pcb each day - results are very good with a small delta we made another test board with TC only in the problem places - same good result we tried 500-600 boards on 12 zone machine - zero defects while on standard 6

Having some issues with 56 contact TQFN. This is low-run prototype situation so no second chances - unfortunately. Part is 5mm X 11mm with .30X .63 perimeter lands and 2.5 X 8.5 thermal pad in center. Issues noted are intermittency at test (basica

We recently got a job where (after placing SMT parts) we have to solder LED dot-matrix 8x8 display modules manually on the pcb. Due to the PCB design, it has to be TH type (also, it's the only type available) and soldered manually (or using selective
