Aluminum substrate quality appraisal

aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single panel consists of a three-layer structure, which are circuit layer (copper foil), insulation layer and metal base layer. Aluminum substrate is a type of PCB board, which is an aluminum-based metal plate. Aluminum substrates are widely used in the electronic field due to their good thermal conductivity, electrical conductivity and mechanical strength. Aluminum substrates can be used in power modules, controllers, etc. in automotive electronics to improve the stability and reliability of automotive electronic systems.

GB/T 31988-2015 Aluminum-based copper-clad laminate for printed circuit

quality product dispute situation:
According to the information provided by the client, the supplier provided the "aluminum substrate" involved in the case to the demander, but the two parties only conducted the transaction through oral agreement and did not sign a written purchase and sale contract. The two parties also did not agree on the technical requirements, material requirements, implementation standards, etc. of the "aluminum substrate" involved. During the
period, the demander discovered that the "aluminum substrate" provided by the supplier was not thick enough, the copper coating (i.e., the protective layer) was prone to bubbling and falling off, and the circuit was easily broken down by current during use, causing economic losses to the demander.
In order to find out the facts, the buyer proposed to conduct quality appraisal of the "aluminum substrate" involved.
quality analysis results: The
appraisal expert group discussed and comprehensively analyzed the relevant information, on-site investigation and product testing data of the "aluminum substrate" involved in the case, and made the following appraisal opinions:
1) The thickness of the "aluminum substrate" involved in the case does not meet the requirements of the "Delivery Order" and GB/T 31988-2015 "Aluminum-based copper-clad laminates for printed circuits".
2) There is no obvious causal relationship between the "aluminum substrate" involved in the case and the LED dead light problem.
