When is controlled impedance required?
Controlled impedance is typically specified for signal paths whose electrical behavior depends on trace geometry and dielectric construction, such as high-speed…
Read answer →How should surface finish be selected?
Surface finish should be selected according to assembly process, component pitch, solderability requirements, storage conditions, reliability expectations, cost…
Read answer →What PCB materials can be reviewed for my application?
Material selection starts with electrical, thermal, mechanical, reliability and compliance requirements. Common projects may use FR4, while high-frequency, meta…
Read answer →How do copper weight and finished thickness affect manufacturability?
Higher copper weight changes achievable line width, spacing, etching balance, plating and thermal behavior. Finished thickness interacts with drill diameter, as…
Read answer →What is the difference between HASL, ENIG, OSP and ENEPIG?
These surface finishes protect exposed copper and support different assembly or connection needs. HASL is common and economical but has surface-flatness limits;…
Read answer →When should HDI, blind vias or buried vias be used?
HDI structures are considered when routing density, fine-pitch packages, board size or electrical performance cannot be achieved with conventional through-hole…
Read answer →What panelization information should I provide?
Provide the finished board outline, preferred array, rail requirements, tooling holes, fiducials, breakaway method and any orientation restrictions. If you do n…
