SMT yield can look healthy and balanced while malfunctioning assemblies still reach clients. This overview explains which KPIs reveal that void and just how to attach printer, SPI, AOI, examination, and field-quality information.
A legitimate SPI calibration timetable need to control prejudice, repeatability, software application changes, ecological drift, and reference-artifact integrity. This overview supplies a risk-based confirmation structure, approval standards, rise regulations, and an audit-ready routine for SMT production.
Fine-pitch placement depends on more than machine precision. This overview explains the procedure manages that prevent QFP and TSSOP soldering flaws.
