What is PCBA? What is the importance of PCBA testing?

Speaking of PCB Everyone is familiar , Then everyone knows what is PCBA Do you ？PCBA It means to be PCB Board proceed SMT Patch 、DIP Plug in and test assembly , Make a finished product , We can understand it as a finished circuit board .PCBA The test is right pcba The board conducts conductivity and output input value detection , that PCBA Why should we do the test ？ Now let's have a brief analysis by muwo technology editor ：
PCBA The production and processing technology of is very complex , Include PCB Fabrication of board 、 Procurement and testing of electronic components 、SMT Patch 、DIP Plug in and other processes , In the process of production , It may cause a series of problems for various reasons , Therefore, professional testing equipment is needed , For example, use a multimeter to detect , To confirm PCBA Whether the board design is perfect .PCBA The importance of testing is reflected in the following points ：
1、 Improve the production capacity of enterprises ：PCBA The higher the passing rate of the test , It will make the qualified rate of products higher and higher , Improve the quality of the product , Promote the production capacity of the enterprise .
2、 Enhance the economic benefits of enterprises ： Only products that stand the test , Users will like , During the test , Find mistakes in time , Adjustment , Make the product more perfect , In this way, the product will be favored by customers when it is put into the market , So as to stimulate the development of economic benefits of enterprises .

PCBA The test generally passes the following forms ：
1、ICT test ： Test circuit 、 electric current 、 Voltage, amplitude and noise .
2、FCT test ： test PCBA The function of , For example, after pressing the key LED Whether the light can be on , Whether the factory settings can be restored .
3、 Fatigue test ： Sampling for high frequency and long-term operation , Observe whether there will be malfunction , To determine the probability of failure , Thus understand PCBA Board performance .
4、 Extreme environmental testing ：PCBA The board is placed in a harsh and extreme environment , Like high temperature 、 severe cold 、 Fall, etc , Pass the test results , Extrapolate PCBA Board Reliability .
Muwo technology believes PCBA Testing is an indispensable part to ensure the quality of product delivery , It determines the performance of the product , Control the quality of products , Reduce the after-sales and repair rate , Let customers trust more , It promotes the win-win cooperation between enterprises and customers .
