PCB Production Process:

Quality Control:

AOI automatic optical inspection is based on optical principles, comprehensively using image analysis, computer and automatic control and other technologies to automatically detect and process PCB defects encountered in production, which can efficiently and accurately screen out defective products and avoid The defective PCB flows to the client or the next process.

Flying probe test, the test probe moves quickly point by point on the PCB circuit board to complete the test.Each test probe is controlled by the precise transmission system to control the movement position, the position accuracy can reach 0.01mm, and the circuit board with higher density and smaller PAD can be tested.

Manual inspection. The company has a strictly complete quality management system. Each link of production is equipped with professional inspectors. From the IQC inspection of raw materials, to the OQC inspection of the shipment can greatly reduce appearance defects

X-RAY inspection equipment can detect the internal structure of ultra-fine pitch and ultra-high-density PCB circuit boards, so as not to damage the PCB,such as bridges, missing pieces, poor alignment, and open circuits.

The 2D measurement uses a 2D image measuring instrument to measure the dimensions of the hole position, length, width, and position.It has become the best high-precision size measuring instrument.

FCT/ICT test, according to the PCB design provided by the customer, including test points, so we build E-test fixture to simulate the input and output of the PCB circuit, and to detect short or open defectives.


Efficient and convenient, shorten the delivery time. JLH TECHNOLOGY CO.,LTD not only has professional PCB engineers and business teams to provide quick quotation and proofing, but also a complete PCBA assembly workshop. When you choose to let Apollo do PCB, Apollo can make PCBA quotation and purchase materials at the same time. When PCB production is completed, the materials and fixtures required by PCBA are ready, and they are immediately transferred to PCBA production. The production is closely connected and there is no need to wait for the process.

Improve the service system to ensure service quality. While we continue to upgrade automation equipment, we also pay more attention to enhancing customer experience. After receiving complete information from customers, we can complete PCB quotations as soon as one hour, and provide customers with free pre-production evaluation of manufacturability, design parameters, and process materials. Suggest or improve the plan. During the production process, the sales staff will promptly report the production progress and production status to the customer, so that the customer can control the production without any worries.

The warranty is 2 year, which is rare in the industry. Strictly manage and control in accordance with IPC standards to ensure the qualified rate of shipment quality. If customers use products in a standardized process, non-PCB external factors cause bad problems, Apollo promises free maintenance within one year. All PCB circuit boards are strictly inspected. In addition to manual visual inspection, we use automatic testing and inspection equipment, such as Flying probe tester, X-ray inspection machine, FCT and AOI automatic optical inspection equipment.
