We begin choose PCB manufacturer after a PCB be finished layout. What jobs do we need to do before we choose the factory? 1. Outputs gerber file and drilling file Some engineer designed the PCB files and sent them to the PCB board factory directly. The PCB board factory has to transform the Gerber files…
Conflict Minerals Sourcing Policy Columbite-tantalite (coltan), cassiterite, wolframite and gold, or their derivatives, including tantalum, tin, and tungsten, originating from the Democratic Republic of the Congo (DRC) and adjoining countries are sometimes mined and sold by armed groups to finance unfair labor practices or human rights violations. Some of these minerals and/or derivatives can make…
Via, through hole, blind hole, buried hole, partial depth hole, countersink hole, back drilling and press-fit hole, is it very dizzy? I will take you to know all kinds of holes in PCB. PCB via PCB via is an important part of PCB. It is the electrical connection guide hole between different layers, joined the…
In the early PCB manufacture, HASL is the most widely used surface treatment, which has excellent welding performance and low cost.With the high precision PCBs developing, it is difficult to below the surface to smooth of HASL, which brings difficulties to SMT mounting. In addition, the service life of HASL board is very short, and…

Explore the key materials used in the fabrication of Printed Circuit Boards (PCBs). Learn about FR-4, metal core PCBs, flexible PCB materials, and more. Discover the advantages and applications of different PCB materials for your electronic design needs.
Ceramic circuit boards are actually made of electronic ceramic materials and can be made into various shapes.Among them, the ceramic circuit board has the characteristics of high temperature resistance and high electrical insulation performance, and has the advantages of low dielectric constant, low dielectric loss, high thermal conductivity, good chemical stability, and similar thermal expansion…
In the design of the circuit board, with the rapid increase of frequency, there will be many interferences different from the design of the low frequency PCB. As the frequency increases and the contradiction between the miniaturization and cost reduction of PCB boards becomes more and more prominent, these interferences are more and more complicated. In…
PCB raw materials will continue to increase in price in 2021 PCB raw materials include copper foil, fiberglass, resin and other related materials have been reported of price adjustments in Q1 of 2021.Recently, from CCL factory to PCB factory, we have received notices about product price increase.Even PCB industry has fired the first shot, pointing out that the…

Do you know the advantages of PCB pouring copper on the surface of the PCB? In the whole process of PCB design, engineers want to ignore the link of pouring copper on the bottom of the PCB in order to save time. Is this right? Is it necessary for the PCB to pouring copper on the bottom of the surface? What are the…
