PCBA testing is an extremely important procedure in the entire electronic manufacturing services (EMS). It is able to strictly control the boards quality in the final stage, find problems in time so as to adjust the previous processes such as SMT and DIP, optimize the process flow, and make quality controllable as a result. Obviously, a good PCBA test fixture will make the entire PCBA process more effective. Here is the common PCBA test fixture to be used in PCBA:
1. ICT Fixture
The ICT mainly includes circuit continuity, voltage and current values, fluctuation curves, amplitude and noise.
2. FCT Fixture
FCT requires IC program firing, simulation testing of the entire PCBA board function, finding problems in hardware and software, and providing necessary production fixtures and test racks.
3. Fatigue Test Fixture
The fatigue test is mainly to sample the PCBA board and perform high-frequency and long-term operation of the function to observe whether there is failure and determine the probability of failure in the test, so as to feedback the working performance of the PCBA board in the electronic product.
4. Environmental Test Equipment
The test in harsh environments is mainly to expose the PCBA board to extreme temperature, humidity, drop, splashing, and vibration, and obtain the test results of random samples to infer the reliability of the entire PCBA board batch product.
5. Burn-In Test Equipment
The burn-in test is mainly to energize the PCBA board and electronic products for a long time, keep them working and observe whether there are any failures. After the aging test, the electronic products can be sold in batches.
Four Reasons Why Choosing Grande To Do SMT
1. Strength Guarantee
▪ SMT factory: With imported SMT machines and multiple optical inspection equipment, which is able to produce 4 million points per day. Each process is equipped with QC personnel who will keep an eye on product quality.
▪ DIP production line: Two wave soldering machines and more than 10 employees who have worked for over three years. That’ s to say, these workers are highly skilled and can weld various SMT & DIP components.
2. Quality Assurance With High Cost Performance
▪ High-end equipment can paste precision special-shaped parts, BGA, QFN, 0201 package. It can also be soldered prototype pcba via SMT machine and placing bulk materials by hand.
▪ Both samples, small and large batches can be produced. And there is no SMT Machine starting cost.
3. Rich Electronic Products SMT Soldering Experience With Stable Delivery
▪ Accumulated services to thousands of electronics companies, involving SMT soldering services for various types of automotive equipment and industrial control motherboards. Furthermore, PCBA products are often exported to Europe and the United States, and the quality is able to be affirmed by new and regular customers.
4. Strong Maintenance Ability & Reliable After-Sales Service
▪ The maintenance engineers have sophisticated experience so that those defective boards caused by all kinds of smt soldering can be repaired. Meanwhile, ensuring the connectivity rate of each circuit board also make sense.
▪Order problems feedback will get response, solution and solved as soon as possible.
