2、Mature process of PCB technology and rich production experience

High-frequency board performance and production process is special, in order to produce the best products, the manufacturer must have rich experience in processing production. PCBONLINE high-frequency PCB manufacturing is controlled from the following points

A、High frequency microwave board is used to transmit high frequency signals. The impedance control requirements of finished PCB wires are strict. The line width tolerance of the printed circuit board is usually ±0.02mm (even ±0.015mm).Therefore, from the perspective of engineering data, our engineers will compensate the line width according to different copper thickness, and the etched board will measure the line width 100% to confirm whether it is within the tolerance range.
B、The high-frequency signal PCB design transmits high-frequency signal rather than current. Pit, notches, pinholes and other defects in the circuit line will affect the transmission effect, and any such minor defects are not allowed in the high-frequency PCB layout. Therefore, after the film is drawn, it must be checked to ensure that there are no pinholes or gaps in the film. The most difficult procedure of high-frequency board fabrication is chemical copper sinking. All holes must have copper and no blank. PCBONLINE adopts Plasma method, which is to inject carbon tetrafluoride (CF4) or argon (Ar2) nitrogen (N2) and oxygen (O2) gas between two high-pressure electrodes under the vacuum environment. The printed board is placed between two electrodes, and the Plasma is formed in the cavity, so as to remove the drilling dirt and dirt in the hole.
C、Solder resistance thickness is also strictly controlled and lines solder mask too thick or too thin for several microns can be disqualified.
D、The final destructive test must be carried out in manufacturing: thermal shock 288℃, 10 seconds, 1~3 times, to ensure no separation of hole wall.

3、Superb process capability, tailor-made for you exclusive technology

4、Advanced production equipment to ensure the processing accuracy of each piece of HF PCB
