How to draw a PCB circuit board from a PCB manufacturing company and know the colors of the PCB circuit board? PCB.
Understanding different series of PCB circuit boards and basic PCB circuit boards can help more developers complete more tasks.
What do people who understand different series of PCB circuit boards know about PCB circuit boards? The advantages of PCB circuit boards and their performance are also important. Do people familiar with FR4 circuit boards know when they need PCB circuit board sampling? On the PCB.

The first characteristic of PCB circuit board production is batch production. With the continuous development of society and electrification, electronic products are constantly updated.
PCB circuit boards are structural components formed by insulation materials supplemented by conductor wiring. When making the final product, its terminal formation refers to the arrangement.
The PCB circuit board we usually see is a component matter, and component layout is required during circuit design. PCB board is a printed circuit board, usually used in engineering.
PCB circuit boards have many different names and can be classified according to their functions: single panel, double-sided board, multi-layer board, and HDI board.

Classified by the size of the insulation layer of copper clad panels: single-sided insulation, double-sided panels, and multi-layer panels. Common types are polyimide, flame retardant and flame retardant.
The cladding substrate for double-sided boards includes: FR-4; Flame retardant and epoxy based materials; Flame retardant and flame retardant substrates.
Double sided board substrate: FR-4; Flame retardant substrate, with a single panel dielectric constant of ≥ 18; Flame retardant grade 94V-0; High frequency board manufacturer and ordinary.
Single sided PCB thickness: 04mm FR-4; Copper thickness: 1oz FR-4; Flame retardant grade UL94-V0;
CEM-3; HDI(+ °C); MELF(+ °C); MCPCB;
(+ °C)。 Z: 65% HDI±15%; J: - > ±10% ±15%; V/f±07%;
DFG: 3-8GHz (maximum 10Gbps); LDO: 10~20 μ A(10GHz。
