A carton of bare boards lands on a customer’s receiving dock in July. Still, the box looks fine. Inside, one panel has a cracked corner. The pads on a second panel have dulled past their solderability window. And the bag that should have shielded the assembly turns out to be pink poly with no metal […]
A stack of bare boards arrived flat, passed incoming checks, and then bowed after the first lead-free reflow. The BGA coplanarity failed, the placement head scraped a panel, and the line stopped for two hours. PCB bow and twist is the measurement that catches this before it happens: for any board carrying surface-mount parts, IPC-A-600 […]
A customer once sent a drawing marked only “IPC standard, high quality.” Their assembler built to Class 2, the industry default, and the first field returns came from a ventilator program that should have been Class 3 from day one. IPC-A-610 Class 3 is the high-reliability workmanship standard: it demands 100% inspection, complete solder wetting, […]
A procurement lead forwarded a quote that looked 30% below the field. Two weeks later the invoice arrived with a stencil charge, an expedite fee, and a component overage they had never seen. An accurate PCBA quote starts long before the price — it starts with the files you send. Send four things upfront and […]
A buyer emailed at 4 p.m.: the microcontroller on their bill of materials just jumped to a 45-week lead time, and their launch date sits 14 weeks out. PCBA component shortages turn a stable build plan into a fire drill overnight. We have lived this more times than we care to count. In practice, the […]
A BGA sits on a medical control board with 400 balls hidden under the body. The AOI vs X-ray inspection question stops being academic the moment a line operator waves the board past the optical camera and it passes — while a 22% void sits inside ball 137, invisible to any lens. We have watched […]
Preserving a solid IC local ground plane beneath high-speed processors is one of the most effective ways to suppress EMI at the source. A 0.5 mm pitch BGA sits on your top layer, and a critical clock trace needs to reach a connector on the opposite side. Do you route directly underneath the package body to save […]
A 0402 capacitor sits 2 mm from the board edge. During SMT assembly, the conveyor rail clamps down and crushes it before reflow even starts. This happens more often than you’d think. In our builds, we see this failure when designers treat the PCB process edge design as an afterthought rather than a first-order constraint. The fix […]
