For a PCB sample, please prepare the following information in advance to inquire about it. Being straightforward and not talking nonsense can save you valuable time. More importantly, we are also experts in preparation, and pricing is not at a loss. The PCB circuit board manufacturer has summarized the following points and hopes to help you.

Material: What kind of material is required for the design of PCB circuit boards? Currently, FR4 is commonly used, and the commonly used material is epoxy resin peeled fiber cloth board.

Board layer: The number of layers for designing PCB circuit boards (the design layers for PCB sampling may vary in price, and the PCB sampling process is similar)

Solder resistance color: There are many colors available, which can be selected according to the company's needs, with the commonly used color being green.

Screen printing color: The font and border color for screen printing on PCB circuit boards, often selected as white.

Copper thickness: Scientific calculation of copper thickness is based on the current of PCB circuit boards. Generally, the thicker the copper, the better. However, the investment cost will be higher, so a reasonable balance needs to be made.

Whether the through-hole is covered with solder mask: Oversolder mask will insulate the through-hole, otherwise it will make the through-hole uninsulated.
