  H igh frequency pcb , High frequency pcb low dielectric constant, high transmission rate, high frequency pcb low dissipation factor, less dielectric loss,   high frequency pcb material  apply to 5G, rail transport and internet of things industry. HUIHE CIRCUITS high frequency PCB has passed ISO9001/ ISO13485 /IATF16949 /UL /RoHS/REACH certification.   FR4 Circuit Board, How To Distinguish Between Ordinary Board And High Frequency PCB   P roduct ? The high-frequency board is pressed with a whole piece of epoxy glass cloth, and the color of the whole board is relatively uniform and bright; at the fracture, you can easily see the white powder with the color of rice by scraping it with your hand or other tools. White. The density is higher than that of ordinary FR4 board, and the weight is heavier.   Ordinary FR4 PCB Board  is made of glass fiber board (composite board). The color of the back substrate is different. Large stripes can be seen on the back ...

  Via In Pad   PCB  board, using copper plating or epoxy to fill holesfor circuit board factor, prevent solder paste or flux from flowing into the via in pad, avoid solder ball getting into via or solder mask cover on pad and cause false soldering. HUIHE CIRCUITS Via In Pad   FR 4 PCB   S heet  has passed ISO9001/ISO13485/IATF16949/UL/RoHS/REACH certification.   What Is A Hole-In-The-Panel Circuit Board? The hole in the disk is an important part of the multi-layer PCB. It is not only responsible for the main functions of the PCB, but also the cost of drilling usually accounts for 30% to 40% of the fr4 circuit board manufacturing  cost. In short, the holes pressed on the pads on the PCB can all be called holes in the disk. Processing Requirements For Hole Plugs In The Disk No solder mask ink entering the hole There should be no tin beads hidden in the hole No explosive oil, ink pads, making it difficult to mount components, etc. Common Sense Of P r...
