What are the differences between different PCB materials?
Comprehensive guide on PCB flammability ratings (HB vs V0), material types (94HB to FR-4), and high-Tg PCBs. Explains Tg benefits, fire standards, and key criteria for substrate materials.
What are some common types of ceramic substrate PCBs?
Ceramic PCBs bond copper to alumina/AlN substrates, offering exceptional thermal conductivity, insulation & durability. Ideal for high-power LEDs, electronics, and demanding heat dissipation applications.
What are the differences between FPC and PCB?
Flexible PCBs enabling bendable, lightweight designs for smartphones, wearables & drones. Offer thinness, high density, & durability vs rigid PCBs. Future driven by innovation.
Why do PCB warp?
PCB warping causes assembly errors, machine damage, & post-solder defects. Driven by material CTE mismatches, uneven copper, lamination issues & stress. Prevention requires design symmetry, material control, specific lamination techniques & post-bake processes.
Is PCB “edge wrapping” important?
PCB edge wrapping adds protective plating/coating to board borders. Prevents corrosion, boosts mechanical strength, enhances solderability, improves EMI shielding & extends lifespan. Vital for reliability.
What problems can occur with PCB soldering?
Common PCB soldering problems (open circuits, shorts, cold joints, etc.): causes include wrong parameters, equipment, materials, technique, & design defects. Solutions provided.
How much do you know about single-sided aluminum PCBs?
Aluminum PCBs excel in heat dissipation for high-power electronics via metal-core structure (circuit, dielectric, aluminum base), offering efficient cooling, insulation, and cost-effective machinability.
