Make the PCB cost as low as possible

In order to make the PCB cost as low as possible, there are many factors that must be considered, Blow SysPCB Shenzhen China PCB maker will give a brief idea for it.

The size of the board is naturally a key factor. The small size the board is the less it will cost. Most of the PCB size has standard for them, as long as you design PCB according to the size, the cost will naturally decrease. Some information about the standard size can be provide by your PCB supplier, China PCB manufacturers especially Shenzhen PCB manufacturers offer competitive price because they located in the biggest electronics city in China.
SMT will use less money than THT, because the parts on the PCB will be more intensive (also small).

On the other hand, if the parts on the board are very dense, it must also be finer wiring, equipment used is also high tech required. At the same time the material used should be more advanced, in PCB design must also be more careful to avoid power consumption and other issues that affect the circuit performance. The cost of these problems bring even more cost than cost reduced by saving PCB size.
The more layers, the higher costs, but fewer PCB layers usually causes an increase of PCB size.
Drilling takes time and consume the drill bit, so the through hole should be as less possible.

Buried vias is expensive than through the vias. Because buried vias must be drilled before compress process, will cause process increase like drill and Plating.
The holes in board are in accordance with the size of diameter of the components pin. If there are different types of parts with different pins, then because the PCB manufacturer can not use the same drill bit for lots of holes drilling on the same board, relatively time-consuming, also the manufacturing costs are relatively increased.
Use fly probe for the electronic test, generally more expensive than optical test for PCB. Normally optical test has been sufficient to ensure that the PCB without any errors.

In short, PCB manufacturers are introducing more complicated machines and equipments for PCB manufacturing process. Learn PCB manufacturing process is very useful, because when we compare the PCB boards from different manufacturers, the PCB performance may be different, the stability may be different, it also allows us to compare the ability of each PCB manufacturer.

Good engineer can have a view the PCB board design, tell that design quality is good or bad. You might consider yourself not so strong, but the next time you get a motherboard or video card, appreciate the beauty of the PCB design for it.
