Quality Assurance
Quality Assurance for Incoming Raw Materials or Components at MorePCB
Quality confirmation and inspection of raw materials, components, and products purchased from suppliers is known as incoming inspection. Sampling is used to verify the quality of the supplied items at their point of origin, and a determination will be made on whether or not the batch should be accepted.
Opting for a reliable platform is key to obtaining top-notch components that precisely meet customer requirements. The parts must also go through a rigorous testing process before being delivered for use.
Incoming Quality Control
Free Design for Manufacturing (DFM) Check
Free Design for Manufacturing (DFM) Check at MorePCB
At MorePCB , we offer a free DMF check to our clients. This includes five aspects: signal and mixed layer checks, power/ground checks, drill checks, solder mask checks, and silkscreen checks.
Our engineers will send engineering queries to the clients when they encounter any discrepancies between the provided information and original files, ensuring that all details are correct.
FAI - Quality Assurance Through Inspection of Initial Unit
First Article Inspection (FAI) is a quality assurance system that provides advanced testing and data platforms to ensure your products meet their design specifications.
Simply enter the bill of materials into the system and it will automatically test the first sample, eliminating potential human errors while saving time, effort and money.
With FAI systems, you can rest assured knowing that all future production will stay within quality standards.
First Article Inspection
Automated Optical Inspection (AOI)
Automated Optical Inspection (AOI)
Automated Optical Inspection (AOI) test is very common in the SMT industry and is suitable for all circuit board production and PCB assembly.
This technology detects soldering issues on components based on their appearance characteristics, the color of each component and the silkscreen information etched onto the ICs.
AOI test is an essential part of SMT production lines and often involves investing in at least one or two pieces of equipment for optimal results.
Automatic X-ray inspection
X-ray inspection is a critical process for circuit boards with certain BGA-packaged components. X-rays have the ability to penetrate materials and were one of the first instruments used in inspections.
The perspective view can provide precise thickness, shape and quality of solder joints as well as solder density which can reveal open circuits, short circuits, hole copper, internal bubbles and insufficient tin.
This helps to make sure that welding quality covers all aspects and can be quantitatively analyzed.
Automatic X-ray inspection
Auto E-Tester
Automatic Fixture Tester
Auto fixture testing is a common procedure used for mass production of PCBs, as it allows for high test efficiency and good results.
However, these tests can be expensive to set up as each circuit board needs its own fixture that is only good for one year.
MorePCB understands the need to reduce labor costs and has purchased several automatic test fixtures to make sure customer requirements are met in terms of quality and delivery.
Burn-In Test
Burn-in tests simulate a product’s daily environment by combining high temperatures, low temperatures, temperature changes and electrical power to identify any defects on the PCBA board.
This can help eliminate or improve problems such as bad soldering or mismatched components, as well as stabilize parameters for defect-free boards.

In-Circuit Test
In Circut Test is usually used on models that have been mass-produced, and the amount of production is usually relatively large, and the test efficiency is high, but the manufacturing cost is relatively large.
Each type of circuit board requires special fixtures and the test cost is very high.
The test principle is similar to the flying probe test. It also measures the resistance between two fixed points to determine whether the components on the circuit have short circuits, empty soldering, and wrong parts.
Function Test
This test method is usually used on some more complicated circuit boards.
The circuit boards that need to be tested must be soldered and passed through some specific fixtures to simulate the formal use of the circuit board.
Place the circuit board in this simulation. In the scene, after turning on the power, observe whether the circuit board can be used normally.
This test method can accurately determine whether the circuit board is normal. But there are also problems of low test efficiency and high test costs.
