Electricity Circuit Component BOM Turnkey PCB Assembly BGA X Ray Inspection
The printed circuit board is abbreviated as PCB, also known as printed circuit board, printed circuit board, etc. It is a circuit board that forms point-to-point connections and printed components on a common substrate according to a predetermined design. Printed circuit boards are an indispensable basic component of electronic information products and are known as "the mother of electronic products". There are many kinds of printed circuit board products, and their classification methods are different. According to the number of layers, printed circuit boards can be divided into single-sided, double-sided, multi-layered boards, etc.; according to different softness, printed circuit boards can be divided into rigid printed circuits. Board (RPC), flexible printed circuit board (FPC) and rigid-flex printed circuit board three categories.
CESGATE stores enough raw materials in our warehouse for a long time to shorten the lead time and reduce the waiting time of customers, Common materials are: KB, Shengyi, Iteq, Nanya, Rogers, Isola, Arlon, Taconic, Ventec, Dupont, Tellon, Panasoic, Berquist., etc.

FAQ
| Q: Why choose us? CESGATE: Professional and experienced R&D team. Advanced production equipment, scientific and reasonable process flow. Reliable and strict quality control system. We test all our products before shipment to make sure everything is in perfect condition. |
| Q: How long does it take for PCB quote? CESGATE: Normally 12 hours to 48 hours as soon as receive internal engineer evaluate confirmation. |
| Q: The Wire Bonding process is required when the circuit board is
printed. What should I pay attention to when making the circuit
board? CESGATE: When making circuit boards, the surface treatment options are mostly "nickel palladium gold ENEPIG" or "chemical gold ENIG". If the Al aluminum wire is used, the gold thickness is recommended to be 3μ”～5μ”, but if the Au gold wire is used, the gold thickness should preferably be more than 5μ”. |
| Q: The lead-free process is required when the circuit board is
printed. What should I pay attention to when making the circuit
board? CESGATE: The lead-free process during printing is higher than the temperature resistance requirements of the general process, and the temperature resistance requirements must be above 260 °C. Therefore, it is recommended to use a substrate above TG150 when selecting the substrate material. |
| Q: Can your company provide the serial number when making circuit
board text? CESGATE: Serial numbers can be provided, and in addition to text serial numbers, QR-CODE can also be provided for customers to query. |
