The five major influencing factors in high-precision PCB assembly

1.high-precision PCB assembly–PCB cost

-(high-precision pcb assembly)Type of board:FR-4、HDI、FPC、Rigid++Flex、IC substrate、aluminium、ceramic
-Layer and Pnl size:Multi-layer boards (＞4 layers) are more complex more than 1/2Layer boards.
If the PCB size is too large ,or too small , it will affect the utilization rate and increase the cost.
-Special process:Buried/Blind hole、Heavey copper、Goldfinger、ENEPIG and so on

2.The types and QTYs of components

-Types of components:Conventional resistors and capacitors have low costs.
However, BGA, QFP, 01005 small components, high-precision ICs, etc.,
Due to the high difficulty in soldering and the high procurement costs, will drive up the prices.
Imported components are more expensive than domestic ones, and they are also supply chain fluctuations affect them.
-Number of components:The more solder joints there are ,
the longer the SMT assembly time will be,and the higher the equipment wear and the labor costs will be.

3.Assembly process and manufacturing requirements

-welding process:The cost of conventional SMT surface mounting is relatively low.
However, if special processes such as BGA welding, selective wave soldering, and nitrogen reflow soldering are involved,.
the equipment and consumables costs will increase.
the high proportion of manual welding will increase costs.
-testing process:The basic AOI optical inspection has a low cost.
However, if X-RAY non-destructive testing, ICT online testing, and FCT functional testing are required,
the more inspection processes there are, the higher the cost will be.

4.Order volume and delivery request

-quantity demanded:For small batches, due to the frequent need for line changes and machine adjustments,
the cost per individual PCB assembly is higher; for large batches ,
the fixed costs such as machine adjustments and stencil cost can be spread out, resulting in a lower unit price.
-D/D request:Urgent orders will incur an urgent cost.

5.Additional services and quality standards

Component procurement model:Bear the risk of component wear and tear
-Quality Certification:Our company has obtained certifications such as lSO and lATF13485, and ourquality inspection process is even more rigorous.
