1. Remove components on single-side printed circuit boards [jlcpcb](jlcpcb.com/m): toothbrush method, screen method, needle method, tin suction device, pneumatic suction gun, and other methods can be used. Most of the simple methods of disassembly of electronic components are only suitable for single-side boards, which has a poor effect on double panel and multi-layer board.
2. Remove components...
# **What is PCB?** #
[PCB](jlcpcb.com/m) also is known as the Printed Circuit Board, is an important electronic component, the supporting body of electronic components, and the carrier of electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.
[JLCPCB](jlcpcb.com/m) is the first and the largest professional PCB prototype...
For electronic engineers, the manufacture of [the circuit board](jlcpcb.com/m) is a necessary step, but the # shortcut of the circuit board # is a much common problem during the manufacture of the circuit board.
A shortcut for the [Printed Circuit board](jlcpcb.com/m) may cause components to burn out and the system to fail, so we must pay attention to it.
Today we would like to analyze the main r...
PCB now is everywhere almost all electronic products show in our life need [PCB Board](jlcpcb.com/m), while nothing will last in good condition forever, when the PCB board get problems, we have to repair it.
Today we will discuss **[how to repair the PCB Board](jlcpcb.com/m)**.
Almost all [PCB repair](jlcpcb.com/m) without drawing materials, so a lot of people are skeptical of circuit board main...
For Electronic amateur, especially for beginners, knowing well for PCB layout is the first step for PCB design or product design. So there are few basic principles here for reference.
A. Follow the layout principle of "big one before small one, difficult one before easy one", that is, important unit circuits and core components should be laid out in priority.
B. The layout shall refer to the pri...
As we can see that increasing number of PCB suppliers appear in our searching engine when we are looking for a suitable [PCB Prototype](PCB Prototype), it may be confusing us which one is the reliable one, here I would like to help with the how to choose the proper PCB prototype supplier;
Fist of all, before you take one long term cooperation PCB prototype company as your partner, you have to fi...
As we know that PCB Prototype is not an emerging industry, so that may cause more PCB prototype companies to get involved in a rat race.
To seize Market share, the most popular way is the price war. So today I would like to recommend [JLCPCB](JLCPCB) as the Winner to provide [the Cheapest PCB Prototype](the Cheapest PCB Prototype). I made a comparison for the most popular 2 PCB prototype companie...
