@pcbsync: One of the costliest mistakes in PCBA is assuming everything is fine just because visual inspection passed. #pcbsync #PCB #pcbdesigner #PCBA #Soldering #x-ray The solder joints appear shiny and perfect, yet the product fails after delivery. This scenario is more common than many realize. A frequent culprit: 👉 Hidden solder joint defects invisible to standard inspections. Especially for BGAs, QFNs, and similar components, issues like internal voids or poor wetting often go undetected. I recall a recent project where all inspections cleared pre-shipment—only for failures to surface during customer testing. That’s when true costs hit: rework, project delays, and sometimes, irreparable damage to customer trust. This is why our standard practice includes: • X-ray inspection for critical components • Rigorous control of the reflow process • Avoiding reliance solely on visual checks Yes, these measures add a bit of upfront cost—but they prevent far bigger losses down the line. I’m curious—how do you approach inspection? Do you rely exclusively on visual methods, or combine several techniques? Let’s discuss best practices for quality assurance.
