HUIHE CIRCUITS high frequency pcb company has passed ISO9001/ ISO13485 /IATF16949 /UL /RoHS/REACH certification. FR4 circuit board, how to distinguish Between Ordinary PCB And High Frequency PCB? The high-frequency printed circuit board is pressed with a whole piece of epoxy glass cloth, and the color of the high frequency circuit 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 pcb, and the weight is heavier. Ordinary FR4 PCB is made of glass fiber board (composite board). The color of the back substrate is different. Large stripes can be seen on the back of the entire board. Check for different types of PCBs. What Failure Phenomenon Will Occur When The Performance Of The High-Frequency Printed Circuit Board Is Poor The poor performance of the high-frequency printed circuit board is mainly due to the low dielectric constant value which affects the working stability of the high-frequency circuit. It may cause signal attenuation, frequency offset drift, and severely stop vibration. The overall electrical performance index is reduced.

The Heavy Copper PCB plating process must achieve the following aspects: 1. HUIHE Circuits heavy copper pcb manufacturer adds a certain value according to the area value calculated by the computer and the empirical constant accumulated in the actual production to ensure the integrity of the plating layer in the hole. 2. When the heavy copper PCB is electroplated for 5 minutes, take out the substrate and observe whether the copper layer on the surface and the inner wall of the hole is intact. It is better that all the holes have a metallic luster. 3. A certain distance must be maintained between the substrate and the substrate. 4. When the heavy copper PCB reaches the required electroplating time, a certain amount of current must be maintained during the removal of the substrate to ensure that the surface of the substrate and the hole will not be blackened or darkened. 5. HUIHE Circuits heavy copper pcb manufacturer according to the mechanical processing floppy disk for trial processing, the first part pre-inspection is carried out, and all the workpieces are processed after meeting the technological requirements. Heavy Copper PCB Manufacturer Quality Control 1. HUIHE Circuits heavy copper PCB manufacturer Strictly implements the first article inspection system to ensure that the product size meets the design requirements. 2.

Applications Of Heavy Copper PCB Heavy copper PCBs shine in applications that demand high power and efficient heat management. Here are some key areas where they are widely used:
Through hole circuit board & half hole PCB, no copper burr residue or warpage in half hole, reduce connectors and save space, apply to Bluetooth module and Signal receiver products. HUIHE CIRCUITS PCB with holes apply to Bluetooth module and Signal receiver products. Our PCB products have passed ISO9001/ISO13485/IATF16949/UL/RoHS/REACH certification. Production process of metallized half-hole PCB For the front inversion, to prevent the quality of the product and the need to make corrections in the later process, the production process of this type of board is processed according to the following process: a drilling (drilling, gong groove-plate surface plating-external Optical imaging-pattern plating-co-drying-half-hole processing-film stripping, etching, tin stripping-other processes-shape Main points of metallized half-hole PCB production The specific metallized PCB half hole are processed in the following way: all metallized half-hole PCB holes must be drilled in the pattern after plating, and one hole at the intersection of the two ends of the half-hole should be drilled before etching. The engineering department formulates the MI process according to the process The metal half-hole is the second-drilled half-hole drilled during the first drilling (or gong), after the image is plated, and before the etching. It is necessary to consider whether the copper will be exposed when the gong groove is shaped, and move the drilled half-hole into the unit. he right hole is drilled first, and then the board is turned over (or mirrored) and the left hole is drilled to reduce the pulling of the copper of the inner hole of the half hole by the drill, resulting in the lack of copper of the hole. The size of the drill nozzle for drilling the half hole depends on the spacing of the contour lines. Draw the solder mask film, use the gong space as a stop point and open the window to increase 4mil treatment. The designer's suggestion when designing the circuit Change the distance from the edge line to the hole center. The general design is to place the hole center on the edge line and move the control center down. For example, the diameter of the hole is 1.4mm, the distance between the two holes is 2.54mm, and the board edge The distance between the line is 0.33mm from the center of the through hole, and the thickness of the plate is 0.6mm. The angle between the tangent to the cut point of the wall and the track of the milling cutter was 90 degrees before, but this time it is about 60 degrees. Because the board edge line is at a certain distance from the center of the through hole, the cutting angle of the milling cutter is changed, and the board thickness is extremely small, so the copper in the hole is not easily pulled out. The simultaneous improvement of small batch pcb design and production can greatly improve the production yield of PCB half-hole boards.
