SMT Assembly Process
1. Place (curing)
Its role is to melt the patch glue so that the surface mount components and the PCB board are firmly bonded together.
The equipment used is a curing oven, located behind the placement machine in the SMT line.
2. Re-soldering
Its role is to melt the solder paste, so that the surface mount components and the PCB board are firmly bonded together. The equipment used was a reflow oven, located behind the pads.
Mounter on SMT production line.
3. SMT assembly cleaning
What it does is remove solder residues such as ux
The assembled PCB is harmful to human body. The equipment used is a washing machine, the location may be
Not fixed, it may be online or offline.
4. SMT assembly inspection
Its function is to check welding quality and assembly quality
The assembled PCB board.
The equipment used includes magnifying glass, microscope, in-circuit tester (ICT), needle tester, automatic optical inspection (AOI), X-RAY inspection system, functional tester, etc.
5. SMT assembly rework
Its role is to rework the failed PCB board
Fault. The tools used are soldering iron, rework station, etc.
anywhere on the production line. As you know, there are some small issues during production, so hand rework assembly is the best way.
6. SMT assembly packaging
PCBMay provides assembly, custom packaging, labeling, cleanroom production, sterilization management and other solutions to provide a complete custom solution for your company’s needs.
By using automation to assemble, package and validate our products, we can provide our customers with a more reliable and efficient production process.
Electronic manufacturing service provider for Automotive, we cover numerous applications:
> Automotive camera product
> Temperature & humidity sensors
> Headlight
> Smart lighting
> Power modules
> Door controllers & door handles
> Body control modules
> Energy management
Third, the prices are different due to complexity and density.
PCB will be different cost even if materials and process are the same, but with different complexity and density. For example, if there are 1000 holes on both circuit boards, the hole diameter of one board is larger than 0.6mm and the hole diameter of the other board is less than 0.6mm, which will form different drilling costs. If two circuit boards are same in other requests, but the line width is different also results in different cost, such as one board width is larger than 0.2mm, while the other one with is less than 0.2mm. Because boards width less than 0.2mm have higher defective rate, which means the production cost is higher than normal.
Fourth, the prices are different because of various customer requirements.
The customer requirements will directly affect the non-defective rate in production. Such as one board accords to IPC-A-600E class1 requires 98% pass rate, while accords to class3 requires only have a 90% pass rate, causing different costs for the factory and finally lead to changes in product prices.
