Double-sided PCB board
Double-sided PCB board is a very important PCB board in the circuit board, the market has double-sided circuit board metal base PCB board, Hi-Tg heavy copper foil circuit board, flat winding double-sided circuit board, high frequency PCB, mixed dielectric base high frequency double-sided circuit board, etc. It is suitable for a wide range of high-tech industries such as: telecommunications, power supply, computer, industrial control, digital products, scientific and educational instruments, medical instruments, automobiles, aerospace defense and so on.
Double-sided PCB Sample
Double-sided PCB proofing, the most commonly used process. At the same time rosin process, OSP process, gold plating process, gold plating, silver plating these processes, in the double panel is also applicable.
Tin spray proceance, the pad is silver, the pad is easy to tin, easy to weld, low price.
Sikkim process: Stable quality, usually used in the presence of Bundin IC.ss: good appear

SMT basic process
SMT basic process elements include: screen printing (or dispensing), mounting (curing), reflow soldering, cleaning, testing, repair
1. Screen printing: Its function is to leak solder paste or patch glue onto the PCB pad to prepare for the welding of components. The equipment used is screen printing machine (screen printing machine), located at the front end of the SMT line.
2, dispensing: it is to drop the glue to the fixed position of the PCB board, its main role is to fix the components to the PCB board. The equipment used is the dispensing machine, which is located at the front end of the SMT production line or behind the testing equipment.
3. Mounting: Its function is to accurately install the surface assembly components to the fixed position of PCB. The equipment used is the SMT machine, which is located behind the screen printing machine in the SMT production line.
4, curing: its role is to melt the patch glue, so that the surface assembly components and PCB board firmly bonded together. The equipment used is the curing furnace, which is located behind the SMT machine in the SMT line.
Our Advantages:
1. Program and functional test and package by Free.
2. High quality: IPC-A-610E standard, E-test, X-ray, AOI test, QC, 100% functional test.
3. Professional service: PCB/FPC/Aluminium Making, SMT, DIP, Component Sourcing, OEM with 21 years experience.
4. Certifications: UL, 94v-0, CE, SGS, FCC, RoHS, ISO9001, ISO14001,IATF16949
