What is a rigid circuit board?

Explore rigid PCB types (single-sided, double-sided, multi-layer), cost factors, rigid-flex alternatives for bendable designs, and essential reliability testing methods.
What is Breadboard and Protoboard?

Breadboards enable quick solder-free prototyping. Protoboards create permanent soldered circuits. Master both for seamless electronics development from testing to final builds.
What are the different types of PCB connectors?

Learn PCB connector types: board-to-board, wire-to-board & wire-to-wire + rugged options. Select by environment, space, assembly to prevent failures & save troubleshooting time.
Which is better, HASL or ENIG?

HASL is cheaper upfront for simple PCBs. Choose ENIG for fine-pitch HDI designs, long-term reliability, or high-speed signals to avoid costly reworks and signal loss.
How to Quick Turn a PCB?

Master rapid PCB strategies: factors affecting quotes, manufacturing timelines, China’s cost edge. Simplify designs, leverage instant quotes to slash lead times and costs.
What is AOI used for?

AOI detects surface PCB defects visually, ICT tests electrical function, X-ray inspects hidden solder joints. All three are essential for comprehensive quality control.
Why do solder pads come off?

Learn why solder pads lift, how heat/stress/quality cause failure & effective fixes. Prevent PCB damage with temperature control, gentle handling & material upgrades.
Efficient PCB Repair: A 5-Step Method

Pro 5-step PCB repair method: inspect, clean, remove, fix, test. Fix burned traces, multilayer boards & solder joints. Save devices without costly replacements.
Why is FR4 the material of choice for most PCBs?

FR4 PCB material balances cost, durability & fire safety. Crucial to know Tg for heat resistance and key design rules to avoid failures like delamination or warping.
What is the difference between aluminum and FR-4 PCB?

Aluminum PCBs excel in heat management for LEDs/power systems. FR-4 suits complex circuits without extreme heat. Choose correctly to avoid failures and extend project life.
