Just start learning computer hardware maintenance technology, only know the melting point of tin is 230 degrees Celsius, if the PCB board unloading capacitor resistors and other components, then the hot air gun should be transferred to a few degrees Celsius will not damage the PCB board?
As the printed circuit board is not a general terminal product, so the name of the definition of a little confusion, such as: personal computer motherboard, called the motherboard, and can not be directly called the circuit board, although the motherboard board there is a circuit board, but Is not the same, so the assessment of the industry when the two can not say the same. For example: because there are integrated circuit parts loaded on the circuit board, so the news media called him IC board, but in essence he is not the same as the printed circuit board. Generally speaking, the printed circuit board refers to the bare board - that is, no upper components of the circuit board.
According to the number of circuit board can be divided into single-sided, double-sided, four-tier, six-board and other multi-layer circuit boards.
Its development has been 100 years of history; its design is mainly layout design; the main advantage of using the circuit board is to greatly reduce the wiring and assembly errors, improve the level of automation and production labor rate.
Printed circuit board {PCB circuit board}, also known as printed circuit board, is the electronic components of the electrical connection provider.
