PCB Assembly
PCB assembly or printed circuit board assembly involves the process of assembling electronic components onto a printed circuit board to create a functional electronic device. The process includes placement and soldering of various components, including surface mount and through-hole devices, as well as testing and inspection of the assembled PCB to ensure quality and functionality.
PCB assembly can be performed by electronic manufacturing services (EMS) providers, printed circuit board manufacturers, and PCBA suppliers. These entities offer a range of services, including rapid prototyping, high-volume production, component sourcing, quality control and value-added services, to meet the specific needs of their customers.
The PCB assembly process usually includes the following key steps:
Component procurement: Purchase electronic components from suppliers based on the bill of materials (BOM) provided by the customer.
PCB production: PCB production according to design specifications, including etching, drilling, soldering mask and silk screen application of copper traces.
Solder paste application: Apply solder paste to the PCB using a stencil to define the area where components will be placed.
Component placement: Use automatic placement machines to accurately position components on the PCB, for surface mount components, and for manual or automatic insertion of through-hole components.
Reflow soldering: Pass the PCB with components and solder paste through a reflow oven to melt the solder paste and form electrical connections.
Inspection and testing: Automated optical inspection (AOI) and in-circuit testing (ICT) are performed to ensure the quality and functionality of the assembled PCB.
Final Assembly: Additional processes such as conformal coating, potting, and mechanical assembly are performed as needed.
PCB assembly is a critical stage in the production of electronic devices, and it is crucial to work with an experienced and reliable partner to ensure successful assembly of high-quality PCBs.
Q&A:
Q: What files do you use in PCBA fabrication?
A: Gerber or Eagle, BOM listing, PNP and Components Position.
Q: Is it possible you could offer sample?
A: Yes, we can custom samples for your testing before mass production.
Q: How much time could I get the quotation after sent Gerber, BOM and test procedure?
A: Within 6 hours for PCB quotation and around 24 hours for PCBA quotation.
Q: How can I know the process of my PCBA production?
A: 7-10 days for PCB production and components purchasing, and 10 days for PCB assembly and Testing.

SMT
The components will be mounted on the circuit board through SMT mounter, and online AOI automatic optical detection will be carried out if necessary. After testing, the perfect reflow furnace temperature curve is set to let the circuit board flow through reflow welding.
DIP
1,The process of DIP processing is: putting in the hole →AOI→ wave soldering → cutting pin →AOI→ correction → washing → quality inspection.
2,After wave soldering, The products will be will scanned by AOI equipment to ensure that no error occurs.
