How to improve the lamination quality of multilayer PCB? PCB has developed from single side to double side and multilayer, and the proportion of multilayer PCB is increasing year by year. The performance of multilayer PCB is developing to high precision, dense and fine. Lamination is an important process in multilayer PCB manufacturing. The control of lamination quality is becoming more and more important. Therefore, in order to ensure the quality of multilayer laminate, we need to have ... -
China Wholesale Flex Pcbs Suppliers - 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... -
China Wholesale Speaker Pcb Board Factories - 6 Layer ENIG impedance half hole PCB – Huihe
About Metallized Half Hole PCB The metallized half hole is a half hole at the edge of the plate and is electroplated. Metallized semi-holes are mainly used for the direct connection between plates. They are mainly used to weld together two printed circuit boards with circuit design technology. The whole system takes up much less space than a PCB system using a row pin connector. Design parameters of half hole PCB Min. Hole Diameter Minimum pad Minimum pad spacing The distance betwee... -

China Wholesale General Pcb Board Quotes - 8 Layer FPC+FR4 Rigid-Flex PCB – Huihe
The birth and development of FPC and PCB gave birth to the new product of Rigid-Flex PCB. Therefore, the combination of flexible PCB and Rigid PCB is a kind of circuit board with FPC characteristics and PCB characteristics, which is formed by combining flexible circuit board and Rigid circuit board together according to relevant process requirements through pressing and other processes. Because Rigid-Flex PCB is the combination of FPC and PCB, the production of FPC and PCB should be equipped ... -
China Wholesale Stabilizer Circuit Board Suppliers - 10 Layer Impedance Control Resin Plugging PCB 3 – Huihe
The difference between electroplating plug hole and resin plug hole 1. Surface difference: The electroplating plug hole is filled by copper plating, and the inner surface of the hole is full of metal. The resin plug hole is filled with epoxy resin after copper plating on the hole wall, and finally copper plating on the resin surface. The effect is that the hole can be conducted, and there is no dent on the surface, which does not affect the welding. 2. The process is different Electroplating ... -
China Wholesale Pcb Stripboard Manufacturers - 8 Layer High TG Impedance Control Fine Pitch PCB 16 – Huihe
Advantages of high Tg PCB 1. Higher stability: if the Tg of PCB is increased, it will automatically improve the heat resistance, chemical resistance, moisture resistance and device stability. 2.Withstand high power density design: if the device has high power density and fairly high calorific value, then high Tg PCB will be a good solution for heat management. 3.When reducing the heat generation of ordinary boards, larger printed circuit boards can be used to change the design and power ... -
China Wholesale Surface Mount Prototype Board Factories - 4 Layer FR4+Rogers PCB 28848 – Huihe
The difficulty of laminated structure of mixed press PCB One of the major challenges in RF/microwave applications is how to ensure that the actual tolerances are within the design tolerances, so as to achieve the desired operating frequency. One of the biggest challenges in the lamination design of mixed-pressure structures is to have uniform thickness between different panels or even between different pieces. Due to the existence of a variety of substrate material types, there are a variety ... -

It includes two forms of laser blind via drilling directly from the surface layer to the third layer, and laser blind... -
China Wholesale Fast Turn Pcb Pricelist - 2 layer ENIG Heavy Copper PCB 15872 – Huihe
Difficulties in drilling heavy copper PCBs With the increase of the copper thickness, the thickness of the heavy copper PCB also increases. heavy copper PCB is usually more than 2.0mm thick, drilling production due to the thickness of the thickness of the plate and copper thick factors, production is more difficult. In this regard, the use of a new cutter, reduce the service life of the drill cutter, section drilling has become an effective solution to the heavy copper PCB drilling. In a... -
China Wholesale Pcb Circuit Manufacturers - 4 Layer ENIG impedance half hole PCB 13633 – Huihe
Half hole splicing mode By using the stamp hole splicing method, the purpose is to make the connecting bar between the small plate and the small plate. In order to facilitate the cutting, some holes will be opened on the top of the bar (the diameter of the conventional hole is 0.65-0.85 MM), which is the stamp hole. Now the board has to pass the SMD machine, so when you do the PCB, you can connect the board too many PCB. at a time After the SMD, the back board should be separated, and th...
