Resin plugging process 1. Definition Resin plugging process refers to the use of resin to plug the buried holes in the inner layer, and then press, which is widely used in high-frequency board and HDI board; it is divided into traditional screen printing Resin Plugging and vacuum resin plugging. Generally, the production process of the product is traditional screen printing resin plug hole, which is also the most common process in the industry. 2. Process Pre process — drilling resin hole — e... -
China Wholesale Circular Circuit Board Suppliers - 16 Layer High TG ENIG PCB – Huihe
High Tg PCB circuit board is basically defined as PCB raw material or designed to withstand high heat resistance in high temperature PCB, high Tg is usually higher than 170 ° C. Therefore, the PCB with TG greater than or equal to 170 ° C is high Tg PCB, which can also be called glass transition temperature. High heat resistance, commonly used in lead-free process. Our advantage 1. Own factory, factory area 12000 square meters, factory direct sales 2. Product 100% test (AOI scanning, 100%... -

HDI PCB material HDI PCB materials are RCC, LDPE, FR4 RCC:Resin coated Copper is short for resin coated copper foil. RCC is composed of copper foil and resin with rough surface, heat resistance and anti-oxidation treatment (used when the thickness is more than 4mil) The resin layer of RCC has the same processability as FR4 adhesive sheet (prepreg). In addition, it should also meet the relevant performance requirements of the laminate, such as: At the same time, because RCC is a new type ... -
China Wholesale Order Printed Circuit Board Pricelist - 8 Layer FPC+FR4 Rigid Flex PCB 4 – Huihe
The Rigid Flex PCB plays a key role in the automotive market The Rigid Flex PCB is becoming more and more important in automotive electronics, which is beyond PCB operators’ original imagination. The reason is that we did not think that the technology used in mobile phone lens module would have the opportunity to extend to the ADAS lens module for car, and further attract the auto component industry to introduce the Rigid Flex PCB into the module products such as photar, and become the entry ... -

China Wholesale Bluetooth Pcb Board Manufacturers - 2 layer High TG ENIG PCB 11590 – Huihe
About High Tg material Tg is the mechanical property that specifies the glass transition temperature, the maximum temperature at which the glass remains rigid.Normal PCB FR4-TG is 130-140 degrees, medium TG is greater than 150-160 degrees, high TG is greater than 170 degrees. Compared with standard FR4, high FR4-TG has better mechanical and chemical heat resistance and moisture resistance.The higher the Tg value, the better the heat resistance of the material, so, especially in the lead-... -
China Wholesale Speaker Circuit Board Factories - 6 Layer ENIG Impedance Control PCB 7736 – Huihe
Why PCB to do impedance? PCB impedance refers to the resistance and the parameters of the reactance, which acts as a barrier to the alternating current. Impedance processing is essential in PCB. Here’s why: 1, PCB to consider the plug installation of electronic components, SMT patch plug also needs to consider the conductivity and signal transmission performance, so it will require the lower the impedance, the better. 2, PCB in the production process through copper deposition, electroplating ... -
China Wholesale Redboard Pcb Factories - 8 Layer ENIG Impedance Control PCB 16978 – Huihe
Deficiencies of the blind buried vias The main problem of blind buried via is the high cost. In contrast, buried holes cost less than blind holes, but the use of both types of holes can significantly increase the cost of a board. The cost increase is due to the more complex manufacturing process of the blind buried hole, that is, the increase in manufacturing processes also leads to the increase in testing and inspection processes. Buried Via Buried vias are used to connect differen... -
