Can provide customized functional testing to ensure product quality

Online AOI, online SPI equipment for testing

What is the difference between high-volume PCB assembly and small-batch PCB assembly?

The difference between large quantities and small batches can be distinguished from the following points：

High-volume PCB assembly essentially means that more than 10,000 pieces can be assembled and produced, while small-batch assembly and production can be purchased from 1 piece.

Large-batch PCB assembly is mainly used in high-end electronic manufacturing organizations, while small-batch PCB assembly is mainly used in industries with low technical requirements.

The process of high-volume PCB assembly is mainly automated to ensure high efficiency. Small-batch PCB assembly allows you to be creative and make your own designs according to your requirements.

Knowledge guide for high-volume PCB assembly and processing

What are the advantages of high-volume PCB assembly?

1. Quality consistency

Since the manufacture of large-scale PCBs uses the same production specifications, this ensures the consistency of PCB assembly products. For large-scale PCB assembly, product testing is carried out in the same batch, so the product quality of large-scale PCB assembly can be consistent.

2. Fast turnover cycle

Through large-scale PCB assembly, products can enter the market faster, which is extremely beneficial for customers competing for a large market share, and helps OEMs speed up production and marketing.

3. Effective cost savings

In Bangyan, we can purchase the required materials in bulk, and we can assemble and produce very quickly. Large-scale PCB assembly can save time and cost.

4. Reduce design costs

Choosing high-volume PCB assembly can carry out one-time PCB design and PCB production process, which can reduce unnecessary PCB design costs.

5. Shorten the assembly time

Due to the use of high-volume PCB assembly, the time required for manufacturing is reduced in the design and prototyping process, and the entire process of high-volume PCB assembly is also automated, reducing manual intervention to save time and energy.

What are the application areas of high-volume PCB assembly?

If you want to enter the high-volume PCB assembly market, you need to reserve knowledge about high-volume PCB assembly. For example, high-volume PCB assembly is usually used in the communications industry, the automotive industry, the aviation industry, and the medical and health industries. Large-volume PCB assembly can be used in large quantities.

What are the processes for high-volume PCB assembly?

Step 1: PCB cleaning

For the first large-scale PCB assembly, the PCB needs to be cleaned to prevent residues or dust on the PCB board from affecting the quality of the PCB assembly products in the later stage.

Step 2: Solder paste printing

You will perform a large-volume assembly process by printing solder paste on the PCB stack. In this process, scrapers and templates will be used to help the welding and printing process, or you can choose jet printing.

Step 3: SPI detection

After the solder paste printing is completed, the solder paste inspection (SPI) should be used to check the entire process, mainly to check the amount of solder paste printing, the height of solder paste printing, the area/volume of solder paste printing, the flatness of solder paste printing, etc.

Step 4: Patch

The process is to accurately place the surface mount components on the PCB pad by moving the mounting head. Since the computer controls everything according to the design, the speed of the process is very fast.

Step 5: Reflow soldering

After using solder paste to connect one or more electronic components to the contact pad, the solder is melted by controlling the heating to achieve permanent bonding, in order to achieve the electrical connection of the connection.

Step 6: Online AOI detection

Through this process, the occurrence of defective welding conditions such as wrong parts, air welding, virtual welding, short circuit, and monument after reflow soldering can be detected to ensure product quality.

What other tests are required for high-volume PCB assembly?

In addition to online AOI testing and online SPI testing, circuit testing and functional circuit testing, X-ray testing, etc. are also required.

Circuit testing (ICT)

In circuit testing, you can use the most detailed test methods to check the quality and integrity of the PCB, and a machine will be used to detect errors in the PCB for correction.

Functional circuit test

Here, you will use a computer with test pins or test probes to test the functional integrity of the PCB. You only need to compare the results with the design specifications to determine whether the circuit board has passed the test.

X-ray inspection

You will use X-ray inspection to detect welding problems that cannot be seen by the naked eye on the PCB. You only need to use X-ray inspection to detect components on the circuit board and errors in welding.

How to choose a suitable high-volume PCB assembly service provider?

There are many high-volume PCB assembly service providers on the market. In order to choose a suitable high-volume PCB assembly service provider, you can start from the following angles: the ability to meet expectations, PCB manufacturing costs, certifications and standards, manufacturing experience, PCB quality turnaround time, responsiveness, etc., choosing the right high-volume PCB assembly service provider can reduce time costs and help products go online quickly.
