About PCBA test instructions
PCBA test refers to the abbreviation of comprehensive tests on PCBA boards for IC programming, line on-off conditions, current, voltage, and pressure. PCBA has many uncontrollable factors in the production process. PCBA testing is a key quality control link in the entire PCBA processing process. PCBA testing standards need to be strictly followed. PCBA testing is a necessary link to strictly control the quality of shipments. Next, I will introduce PCBA test instructions to you

There are currently five main forms of PCBA testing: ICT testing, FCT testing, aging testing, fatigue testing, and testing under harsh environments.

Among them, the ICT (InCircuit Test) test mainly includes the on-off, voltage and current value, fluctuation curve, amplitude, noise and other related circuit tests of the circuit;

The FCT (Functional Circuit Test) test requires IC program firing, simulates the function of the entire PCBA board, finds problems in the hardware and software, and is equipped with necessary production fixtures and test racks for cooperative operation;

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 burn-in test, the electronic products can be sold in batches, mainly for the life of the finished product. The test guarantee; the fatigue test is mainly to sample the PCBA board and perform functional high-frequency and long-term operation to observe whether the product fails, such as clicking the mouse for 100,000 times or turning on and off the LED light 10,000 times, and the test appears The probability of failure to feed back the working performance of the PCBA board in the electronic product;

The test under severe conditions (SevereConditions) mainly exposes the PCBA board to the extreme working environment, and obtains the test results of random samples under continuous operation by adjusting the temperature, humidity, drop, splashing, and vibration, thereby inferring the entire PCBA board Reliability of batch products.

After the final product has undergone a series of PCBA tests, the PCBA board with no problem can be affixed with a qualified label, and finally it can be packaged and shipped.
quality assurance
iPCB has passed ISO9001:2008, ISO14001, UL, CQC and other quality management system certifications, and produces standardized and qualified PCB products. We master complex process skills and use professional equipment such as AOI and Flying Probe to control production, X-ray inspection machines, etc. . Finally, we will use double FQC inspection of appearance to ensure shipment under IPC II standard or IPC III standard.
