Frequently Asked Questions
In short, an appropriate amount of solder paste is coated on the solder pad of the PCB, and then the chip component is placed on the printed circuit board at the specified position, and finally the printed circuit board with the attached component is welded through the reflux oven.
"Yes". We strive to provide customers with fast turnaround PCBA services in various ways to meet your needs for fast turnaround PCBA
Standard quickturn times vary depending on the type and number of PCB components. Here are some examples.
1) Fast transfer PCBA service time is 1-5 days.
2) PCB assembly alone takes 1 week.
3) Turnkey PCB assembly or mass production time is 2-3 weeks.
4) Take 4 to 10 weeks for turnkey box assembly.
Below is a brief overview of some of the factors that affect the cost of PCB assembly.
1) Technology used: The assembly process can use surface mounting or through hole technology. Sometimes, some components may require the use of both technologies, but this increases the cost.
2) The number of layers of the board: The cost of a single-sided PCB component is usually lower than the cost of a double-sided or multi-layer PCBA.
3) Component size: Usually, using smaller components and making densely assembled boards will increase the cost.
4) The total number of components.
5) Compliance: Frequent multiple testing to ensure assembly compliance also adds to the cost.
6) Required process: Some PCB components may require a series of processes, such as wave soldering, X-ray inspection, automatic optical inspection, manual welding and other processes. These can add significantly to costs.
7) Flexible or rigid PCB components: Generally, the cost of flexible PCB components is higher than the cost of rigid PCB components.
8) Conformal coating: Cost is also affected by conformal coating requirements. The number of layers of conformal coating affects the cost.
9) Testing: From thermal cycling to circuit testing, many tests need to be carried out before shipping.
10) Packaging requirements: Special packaging requirements may lead to increased costs. Delivery: Costs may increase if expedited delivery times are required.
We can follow these steps to find a reliable PCBA supplier with the best PCB assembly services:
1) Find 5-10 PCB assemblers, view their experience, certification and customer reviews, and then narrow down to 3;
2) Send documents to 3 PCBA suppliers, check their prices, and understand their services after communication;
3) Select the best PCBA manufacturers to start trial orders.
Do you offer testing and inspection services for PCB assemblies?
Yes, we do all kinds of tests and inspections for printed circuit board assembly.
1) First piece inspection
2) Solder paste inspection
3) Automatic Optical Inspection (AOI)
4) Visual inspection
5) BGA X-ray examination
6) Incoming quality control
7) Process quality control
8) Quality assurance
9)ICT(Online Testing)
10)Functional Testing (FCT)
11) PCB on/short test
12) Flying probe test

5) Laminating machine
6) LDI exp
As mentioned above, PCB is short for printed circuit board. It is the carrier of electronic components. All components are connected via PCB to achieve electronic functions. PCB assembly is short for printed circuit board assembly. It refers to the process of welding components to the PCB. PCBS and components have their functions, but they only work as fully functional products after they are all soldered together.
