Before approval, suppliers must be assessed by Aoshuo's supplier evaluation team. In addition, we will evaluate and rank every supplier once a year to ensure that they offer materials that satisfy our standards. In addition, we continually develop suppliers and encourage them to enhance their quality and environmental management based on ISO9001 standards.

Before moving to the warehouse, all materials in Aoshuo must be verified and approved. To manage the incoming, Aoshuo implements tight verification methods and operating instructions. Aoshuo also has a variety of precision inspection instruments and equipment to ensure the capacity to accurately assess whether the verified material is excellent or not.

First Article Confirmation is an essential step in the testing and verification of a Printed Circuit Board Assembly (PCBA). This process involves comparing the actual components that are used in the assembly with the reference design to check for accuracy in terms of size, Quantity, type, and specification. This enables the manufacturer to quickly and accurately identify any discrepancies or incorrect components that may have been used in the assembly. Additionally, it also helps to ensure that the products match the customer's requirements and specifications. First Article Confirmation is an important step in quality control and a vital part of the process for PCBA manufacturing.

Automated X-ray inspection uses X-ray technology instead of visible light, to automatically inspect features which are typically hidden from view.The increasing usage of ICs with packages such as BGAs, for which the connections are underneath the chip and not visible, means that ordinary optical inspection is impossible. AXI is able to find faults such as opens, shorts, insufficient solder, excessive solder, missing electrical parts, and mis-aligned components. These inspection systems are more costly than ordinary optical systems, but they are able to verify all the connections.

Automated Optical Inspection (AOI) Testing is a critical component of quality control in PCBA Manufacturing. AOI Testing uses an automated visual inspection of the printed circuit in order to detect any irregularities, defects, or inaccuracies. This process uses an advanced camera system that autonomously scans the device to detect any problems that human eyes cannot see, thereby saving time and resources in detecting any problems on the PCB board. AOI Testing can detect discrepancies in size and shape, component skew, missing or incorrect pads, and missing components. This type of testing helps to identify any problems before mass production begins, thus improving the quality and reliability of the final product.

Function Test for PCBA manufacturing is a critical step in the overall quality assurance process. The purpose of this test is to identify any problems or issues in the board's functionality, before the product is released. The test can include a range of tests such as functionality testing, power-on testing, and current consumption testing. If any issues are detected, the manufacturer can address them before product shipping, resulting in a more reliable product and greater customer satisfaction. With the Function Test for PCBA manufacturing, manufacturers can ensure that their products are of the highest standard and meet their customers' expectations.
