    • China Wholesale Rohs Circuit Board Quotes - 2 Layer High Tg ENIG PCB – Huihe

      China Wholesale Rohs Circuit Board Quotes - 2 Layer High Tg ENIG PCB – 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 Turnkey Pcb Quotes - 8 Layer FPC+FR4 Rigid Flex PCB – Huihe

      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 bric...

It is the best choice for low weight PCB. 3.Multilayer PCBs have smaller sizes and save space. 4.EMI is very simple and flexible. 5.Durable and powerful. Application Of Multilayer PCB Multilayer PCB design is the basic requirement of many electronic components:   Accelerator Mobile Transmission Optical Fiber Scann...
    • China Wholesale Non Printed Circuit Board Suppliers - 8 Layer HASL PCB – Huihe

      China Wholesale Non Printed Circuit Board Suppliers - 8 Layer HASL PCB – Huihe

      Why Are Multilayer PCB 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 o...

    • China Wholesale Circuit Board Manufacturers - 6 Layer ENIG Blind Vias PCB – Huihe

      China Wholesale Circuit Board Manufacturers - 6 Layer ENIG Blind Vias PCB – Huihe

      Features Of The Blind Via PCB Blind Vias are located on the top and bottom surfaces of the circuit board and have a certain depth for the connection between the surface circuit and the inner circuit below. The depth of the hole usually does not exceed a certain ratio (aperture). This way of production will need to pay special attention to the depth of the hole (the Z axis) to the right, do not pay attention to words will cause difficult hole plating so almost no factory used, can also be...

      China Wholesale Gps Tracker Circuit Board Pricelist - 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 l...
    • China Wholesale Mosfet Pcb Factories - 4 Layer ENIG Half Hole PCB – Huihe

      China Wholesale Mosfet Pcb Factories - 4 Layer ENIG Half Hole PCB – Huihe

      Half Hole PCB Splicing Method 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, ...

      China Wholesale Pcb Assembly Services Manufacturers - 4 Layer ENIG Blind Buried Via PCB – Huihe

      About The HDI PCB Due to the influence of drilling tool, the cost of traditional PCB drilling is very high when the drilling diameter reaches 0.15mm, and it is difficult to improve again. The drilling of HDI PCB board no longer depends on the traditional mechanical drilling, but uses laser drilling technology. (so it is sometimes called laser plate.) The drilling hole diameter of HDI PCB board is generally 3-5mil (0.076-0.127mm), and the line width is generally 3-4mil (0.076-0.10mm). The...
