The PCBA test plan not only affects the quality of debugging, but also affects the improvement of test work efficiency. PCBA testing needs to formulate detailed plans in advance according to requirements.
How to develop a PCBA test plan
The test plan refers to the development of a set of content and methods suitable for the debugging of a certain type of electronic product, so that the test work can proceed smoothly and achieve good results. It should include the following basic content:
a. The content of the test should be specifically formulated according to the standards promulgated by the country or enterprise and the grade specifications of the product to be tested.
b. Selection of test equipment (including various measuring instruments, tools, special test equipment, etc.).
c. Test methods and specific steps.
d. Test conditions and related precautions.
e. Test safety operating procedures.
f. Data and record forms required for testing.
g. The amount of man-hours required for the test.
h. Signature of the person in charge of the test and handover procedures.
All the above contents should be reflected in the relevant process documents and tables as far as possible.
Basic principles for formulating PCBA test plan
For different PCBA products, the test plan is different, but the principles and methods formulated have commonality.
a. According to the product specifications, grades and the main trend of the product, determine the test items and main performance indicators.
b. On the basis of understanding the working principle and performance indicators of the product, focus on understanding the role, parameters and allowable range of key components and components in the circuit that affect the product performance. This will not only ensure the focus of the test, but also improve Test work efficiency.
c. Consider the adjustment of each component itself and the coordination between each other, especially the coordination of each part, because this often affects the realization of the performance of the whole machine.
d. When testing the PCBA prototype, consider the mass production conditions and requirements, that is, to ensure the consistency of product performance indicators within the specified range, otherwise it will affect the product's qualification rate and reliability.
e. It is necessary to consider the existing equipment and conditions, make the debugging methods and steps reasonable and feasible, and make the operator safe and convenient.
f. Try to use advanced technology to improve production efficiency and product quality.
g. During the debugging process, do not let go of any abnormal phenomena, analyze and summarize in time, take new measures to improve and improve, and provide valuable experience and data for the new debugging process.
h. For the formulation of PCBA test plan, the more specific the debugging content, the better, and the operability is strong. The test conditions should be written carefully and clearly, the debugging steps should be organized, and the test data should be tabulated as much as possible to facilitate observation, understanding and comprehensive analysis. The content of the safety operation regulations should be specific and clear. Selection and configuration of debugging instruments.
