China Wholesale Flexible Pcb Prototype Manufacturers - 4 Layer ENIG Blind Buried Via PCB – Huihe
About the HDI 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 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 board is generally 3-5mil (0.076-0.127mm), and the line width is generally 3-4mil (0.076-0.10mm). The size of pad... -
China Wholesale Ic Pcb Board Factories - 6 Layer High TG Leadless Golden Finger PCB – Huihe
When need high temperature PCBs? If the working temperature of the product is higher than 130 ℃, a high Tg PCB is required to ensure safety. The main reason for using high Tg PCB is that the PCB needs to comply with RoHS directive, and the temperature required for lead-free solder flow is high, resulting in the substrate of printed circuit board needs to be high Tg material. Application of the High Tg PCB TG PCB is used in electronic industry which can run at higher temperature. By ... -

China Wholesale Quick Turn Flex Circuits Factories - 6 Layer ENIG via-in-pad PCB 16842 – Huihe
The advantages and disadvantages of plugging and no plugging? In terms of plug holes, they have the following advantages 1. the plug hole can prevent PCB through the wave soldering tin from the through hole through the component surface caused by short circuit; That is to say, within the scope of the wave soldering design area (generally the welding surface is 5mm or above) there is no hole or hole to do plug hole treatment. 2. The plug hole protects against possible short circuits caused by ... -
China Wholesale Rf Pcb Quotes - 6 Layer ENIG Blind Vias PCB 27809 – Huihe
Features of the Blind Via 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 connecte... -

China Wholesale Cpu Pcb Suppliers - 4 layer Taconic ENIG PCB 53 – Huihe
About PTFE PCB PTFE (commonly known as Teflon) is an ideal dielectric for RF applications, but it is not easily compatible with the conventional dielectric FR4 in PCB manufacturing. Ceramic dielectric is the most commonly used dielectric material in multilayer PCB. It can be used as a separate dielectric layer in special applications and as an inner dielectric layer in FR4 laminated structure in conventional applications. Many RF signal layers of RF design have large non copper filled ar... -

About Via-In-Pad PCB The Via-In-Pad PCBs are generally blind holes, which are mainly used to connect the inner layer or the secondary outer layer of HDI PCB with the outer layer, so as to improve the electrical performance and reliability of electronic products, shorten the signal transmission wire, reduce the inductive reactance and capacitive reactance of the transmission line, as well as the internal and external electromagnetic interference. It’s used for conducting. The main problem... -
China Wholesale Custom Pcb Board Quotes - 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 Pcb Board Power Supply 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...
