China Wholesale Pcb Service Pricelist - 6 Layer HASL Blind Buried Via PCB 13699 – Huihe
Features of the Buried Via The manufacturing process cannot be achieved by drilling after bonding. Drilling must be performed at individual circuit layers. The inner layer must be partially bonded first, followed by electroplating treatment, and then all bonded finally. This process is usually used only on high-density PCBs to increase the available space for other circuit layers The basic process of making HDI blind buried Via PCB Equipment display Automatic Plating Lin...

China Wholesale Multilayer Pcb Board Pricelist - 4 layer Medium TG ENIG PCB 13270 – Huihe
About High Tg PCB High Tg means high heat resistance. With the rapid development of the electronic industry, especially the electronic products represented by computers, the development of high functionalization and high multilayer requires the higher heat resistance of PCB substrate materials as an important guarantee. With the emergence and development of high density installation technology, such as SMT and CMT, PCB is increasingly dependent on the support of high heat resistance of t...

China Wholesale Custom Circuit Board Printing Suppliers - 4 Layer FPC+FR4 Rigid Flex PCB 20 – Huihe
Design rules and precautions of Rigid Flex PCB The design of rigid flex PCB is much more complex than the traditional PCB design, and there are many places to pay attention to. In particular, the rigid flexible transition area, as well as the related wiring, through-hole design, all need to follow the requirements of the corresponding design rules. 1. Through hole position In the case of dynamic use, especially when the soft plate is often bent, the through holes on the soft plate should...

China Wholesale Universal Pcb Pricelist - 4 Layer FR4+Rogers PCB 29166 – Huihe
About High-frequency mixed-voltage PCB High-frequency mixed-voltage circuit boards are pressed using different laminated materials to optimize electrical performance and improve system reliability. The biggest challenge in manufacturing this type of high frequency PCB is to match the thermal expansion coefficient (CTE) of the different materials to fit the PCB manufacturing and component assembly. Typically, such circuit designs include a combination of FR-4 materials and PTFE laminated ...

China Wholesale Single Circuit Board Factories - 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 Fast Turn Pcb Factories - 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%...

China Wholesale Multilayer Flex Circuits Manufacturers - 4 Layer ENIG Impedance Control PCB 9115 – Huihe
About the impedance control In the case of transmission of high frequency signals, the controlled impedance helps to ensure that the signal does not decay significantly during transmission. In essence, controlled impedance refers to the matching of the material properties of the substrate to the characteristics of the line/dielectric layer to ensure that the impedance value of the line signal is within the tolerance of the reference value. Controlled impedance PCBs provide reliable and c...

China Wholesale Rigid Printed Circuit Board Manufacturers - 8 Layer ENIG Impedance Control PCB – Huihe
Impedance is the combination of capacitance and inductance to hinder the circuit under high frequency signal. Impedance is an AC characteristic, which means it is frequency dependent. In the case of transmitting high-frequency signals, the controlled impedance helps to ensure that there is no significant attenuation of the signal during transmission. In essence, the controlled impedance means that the material characteristics of the substrate match the characteristics of the line / dielectric...

China Wholesale Flex Printed Circuit Board Manufacturers - 8 layer HASL PCB circuit board – Huihe
Why are multilayer boards mostly even? Due to the lack of a layer of medium and foil, the cost of raw materials for odd PCB is slightly lower than that for even PCB. However, the processing cost of odd layer PCB is significantly higher than that of even layer PCB. The processing cost of the inner layer is the same, but the foil/core structure significantly increases the processing cost of the outer layer. Odd layer PCB needs to add non-standard lamination core layer bonding process on th...

China Wholesale Universal 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...
