  • Special requirements for the production of halogen-free PCB
    • August 13, 2019

    Based on the relative particularity of the base material, halogen-free PCB also has special requirements in fabrication. The main performance is as follows: Lamination Lamination parameters will be different because of different based materials. Take the raw substrate and PP as the multi-layer board mentioned above, in order to ensure the sufficient flow of the resin and the good bonding force , t...

  • Halogen-free PCB, how much do you know?
    • August 13, 2019

    Within the classification of board, we have a type of pcb circuit board called halogen-free board. So, how much do you know about halogen-free PCB. What is a halogen-free base material? According to the JPCA-ES-01-2003 standard: a copper clad laminate having a chlorine (C1) and bromine (Br) content,which respectively less than 0.09% Wt (weight ratio), It is defined as a halogen-free copper clad la...

  • Why the lines on the PCB board are not straight, but various turns?
    • August 13, 2019

    The lines are commonly showed on our conventional pcb boards ,which are dominated by straight lines. But why are some lines on the PCB board not straight, sometimes are with various turns? This blog will explain the specific reasons through example. The pic shown above is the DDR memory module which belongs to high-speed PCB. The design of high-speed PCB must ensure the integrity of the signal in ...

  • Process and equipment needed for PCB production
    • August 02, 2019

    The production of circuit boards is a relatively complicated process. In each production process ,It basically requires corresponding equipment for processing, which need to put a lot of energy and cost. This blog is going to introduce you the the process and equipment needed for PCB production. During the PCB manufacturing process, the following production equipment is needed: 1. Engineering prod...

  • The short out inspection method for PCB circuit board
    • August 02, 2019

    There are many kinds of faults that can occur during the assembly process of PCB boards. Short out is one of the common situations. So how do we check the board for a short circuit? Here are some of the methods we use: 1. If it is artificial welding, it is necessary to develop a good habit. First, visually inspect the PCB board before soldering, and use a multimeter to check whether the critical c...

  • What is the specific difference between PCB and FPC?
    • May 05, 2019

    PCB (Printed Circuit Board) is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made by electronic printing, it is called a "printed circuit board". FPC: flexible circuit board (flexible PCB): referred to as "soft board", also known as "flexible circuit board", also known as "soft circuit board...

  • How to distinguish the quality of the circuit board
    • April 22, 2019

    With the rapid development of mobile phones, electronics and communications industries, it has also contributed to the continuous growth and rapid growth of the PCB circuit board fabraction industry. But the question that comes with it is, how do we distinguish the quality of the PCB circuit board? We can mainly start from two aspects; the first method is to judge from the appearance; on the other...

  • Why we choose multi-layer design in high-speed PCB boards?
    • April 22, 2019

    As we all know, multilayer pcb boards are recommended for high speed PCB boards. But why is that? This blog tells you the reasons. Firstly, the multi-layer board distributes the inner layer exclusively for power and ground. Therefore, It has the following advantages: ·The power supply is very stable; ·The circuit impedance is greatly reduced; ·The wiring length is greatly shortened. In addition, f...

  • The common fault dialysis for PCB printed circuit board
    • April 22, 2019

    During a series of PCB fabrication processes, there are a lot of matching points. If you are not careful enough, the board will be flawed and the quality of the PCB will end up in an endless stream. Let's share with you the failure of the PCB board and its solutions. 1. PCB board often stratifies in service the reasons: (1) materials or process issues (2) inappropriate design and poor copper distr...
