Common forms and operating steps of PCBA testing

(Summary description)In PCBA production and processing, testing is an indispensable link. The purpose is to ensure reliable production and delivery quality, normal operation of product performance, and to find out poorly assembled circuit boards. This kind of test is generally performed by simulating the assembly of the circuit board into a complete machine for full-function testing, which can effectively avoid the situation where a defective circuit board is found after assembly into the complete machine and then disassembled and reassembled, so as to avoid waste of working hours and other material losses.
However, PCBA testing is also divided into various forms, the following Sanjing will let everyone know about it.
First of all, the first is the ICT test. This kind of test is mainly to detect the voltage and current values of the test points after the PCBA is energized. It does not involve function keys or input and output tests. It mainly includes circuit on and off, voltage and current values and fluctuation...

Information

In PCBA production and processing, testing is an indispensable link. The purpose is to ensure reliable production and delivery quality, normal operation of product performance, and to find out poorly assembled circuit boards. This kind of test is generally performed by simulating the assembly of the circuit board into a complete machine for full-function testing, which can effectively avoid the situation where a defective circuit board is found after assembly into the complete machine and then disassembled and reassembled, so as to avoid waste of working hours and other material losses.

 

However, PCBA testing is also divided into various forms, the following Sanjing will let everyone know about it.

 

First of all, the first is the ICT test. This kind of test is mainly to detect the voltage and current values of the test points after the PCBA is energized. It does not involve function keys or input and output tests. It mainly includes circuit on and off, voltage and current values and fluctuation curves, amplitude, noise, etc.

 

 

The second is the FCT test. This kind of test requires IC program firing, simulation test of the function of the entire PCBA board, discovery of problems in the hardware and software, and equipped with necessary patch processing production jigs and test racks.

 

So what are the specific steps for this test? Sanjing will give you a brief introduction.

 

First, the first step is to make FCT test fixtures according to the test points, procedures, and test steps designed by the customer.

 

Secondly, connect the test points on the PCBA test rack through the FCT test rack to form a complete path.

 

3. Connect the PCBA board to the computer and the burner, upload and run the MCU program.

 

4. Observe the voltage and current values between the test points on the FCT test frame, and verify whether it is consistent with the design, so as to complete the test of the entire PCBA board.

 

The above is about the common forms and operation steps of PCBA testing, I hope it can be helpful to everyone!
