How is the motherboard (board) manufactured?
PCB manufacturing process by glass epoxy (GlassEpoxy) or PCB "substrate" made of similar materials begins. The first step in the production is to light the wiring between the parts, using negative transfer (Subtractive)
The transfer method "prints" the printed circuit board of the printed circuit board onto the metal conductor.
The trick is to lay a thin layer of copper on the entire surface and remove the excess. If a double panel is made, the substrate of the PCB will be covered with copper foil on both sides. The multi-layer board can be used to "press" the two double-sided panels with special adhesives.
Next, you can drill and plate the required components on the PCB. After drilling the machine according to the drilling requirements, the hole must be plated (plated through hole technology, Plated-Through-Hole
Technology, PTH). After metal treatment inside the hole, the internal layers can be connected to each other.
Before starting the plating, the debris in the hole must be removed. This is because the resin epoxy will have some chemical changes after heating, and it will cover the inner PCB layer, so it must be removed first. Both the removal and plating operations are done in the chemical process. Next, it is necessary to cover the solder resist (solder resist ink) on the outermost wiring so that the wiring does not touch the plating portion.
Then, the various component markings are printed on the circuit board to indicate the position of each part. It cannot cover any wiring or gold fingers, otherwise it may reduce the solderability or the stability of the current connection. In addition, if there is a metal connection, the “golden finger” part is usually plated with gold, so that a high-quality current connection can be ensured when inserted into the expansion slot.
Finally, it is tested. Test the PCB for shorts or open circuits and test it optically or electronically. Optical scanning is used to find defects in each layer, and electronic testing is usually done with a Flying-Probe to check all connections. Electronic tests are more accurate in finding short circuits or open circuits, but optical tests can more easily detect problems with incorrect gaps between conductors.
After the circuit board substrate is completed, a finished motherboard is equipped with various components on the PCB substrate as needed. Firstly, the SMT automatic placement machine is used to "weld" the IC chip and the chip component, and then manually connect it. Insert some of the machines that can't do the work, and fix these plug-in components on the PCB through the wave/reflow soldering process, so a motherboard is produced.
In addition, if the board is to be used as a motherboard on a computer, it needs to be made into different boards. The AT board type is one of the most basic board types, characterized by simple structure and low price. Its standard size is 33.2cmX30.48cm. The AT board needs to be used together with the AT chassis power supply and has been eliminated. The ATX board is like a large AT board. This makes it easy for the ATX chassis fan to dissipate the CPU. Many of the external ports on the board are integrated on the motherboard, unlike many COM ports on the AT board. The print port must rely on the connection to output. In addition, ATX also has a Micro
The ATX small form factor supports up to four expansion slots, reducing size and power consumption and cost.
