PCBA testing (AOI, ICT, FCT) catches defects early, prevents recalls & saves costs. Choose methods by risk, budget & volume. Systematically debug failures to protect

Identify AC control board warning signs like random shutdowns, understand replacement costs ($150–$700), select exact replacements, and safely source boards from China suppliers.

Understand why PCBA costs exceed PCB: component sourcing, precise assembly (SMT/THT), and rigorous testing (X-ray, functional checks) add labor, materials, and engineering expenses.

Solve faulty switches with the right PCB switch type: push-button, toggle, slide, or membrane. Learn selection criteria, design rules, and China sourcing tips for reliability.

Instant PCB prototypes without outsourcing? DIY milling saves days but demands expertise. Master waste reduction, bit selection, and workflow to avoid costly errors & bottlenecks.

Fix weak PCB wireless signals: select antenna types (monopole/shark fin), calculate dimensions using wavelength formulas, optimize materials (Rogers/PTFE), and ensure mass-production resilience.

AOI is critical for SMT assembly, detecting placement/soldering defects early. Choose 2D vs 3D AOI based on component complexity. Combine with SPI/AXI & AI for

Master critical PCB layers: signal routing, power/ground planes, substrates & materials to prevent overheating, signal chaos, and costly redesigns. Ensure reliability.

Master PCB schematics: structured workflows, avoid symbol-layout errors, use hierarchical design. Transform logical concepts into manufacturable boards efficiently.

Master PCB heatsink selection: calculate heat output, optimize placement/layout, and choose active/passive cooling. Prevent overheating failures and boost device reliability.
