Which IC packages dominate modern electronics?

Master IC package selection: BGA for high-speed/high-pin, QFP for cost efficiency. Unlock chiplet/3D performance gains and conquer signal/thermal challenges with proven PCB strategies.
What is BGA soldering?

Master BGA soldering: Prevent bridging/voids with precise temp control, baking & flux. Essential tools: stencils, reflow ovens, X-ray inspection ensure reliable high-density connections.
What is a blind via?

Blind vias save space in dense PCBs by connecting outer to inner layers selectively. Essential for HDI designs like smartphones, they optimize routing & thermal management, but increase cost 15-30%. Combines with microvias.
What are the most common PCBA testing methods?

PCBA testing (AOI, ICT, FCT) catches defects early, prevents recalls & saves costs. Choose methods by risk, budget & volume. Systematically debug failures to protect reputation & profits.
What are the signs an AC control board is failing?

Identify AC control board warning signs like random shutdowns, understand replacement costs ($150–$700), select exact replacements, and safely source boards from China suppliers.
Why Does PCBA Cost More Than PCB?

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.
What Is a PCB Switch?

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.
