Reflow semiconductor
WebFlip-Chip Flux. The flip-chip process involves taking the singulated die from a wafer mounted on a wafer dicing tape, inverting ("flipping") them and placing them onto a substrate. The substrate may be a printed circuit … WebPre-reflow: Use visual inspection to verify solder paste dispense location and quantity. Pick and place: Use machine vision as necessary to ensure proper component placement. Post reflow: Use electrical testing to verify solder joint formation (100% post-reflow visual inspection is not recommended). 4. Cleaning Recommendations
