Analysis of difficulties in the production process of aluminum substrate

*Oxidation disposal of aluminum plate：Strong oil flushing - Neutralization of dilute nitric acid - Coarsening - oxidation - Acid-base neutralization - Sealed bake. Each process must ensure the quality, otherwise it will affect the cohesive force of the aluminum substrate.

*The whole production process should not wipe the base surface of the aluminum substrate, nor touch the aluminum base.Otherwise, it will affect the adhesion of the aluminum substrate.

*The insulating layer of the aluminum substrate must be kept clean and dry, impurity affects its compression function, And wetting can easily be stratified. 

*Protective film needs smooth, and no idle or bubble will be invented.Otherwise, the aluminum substrate will rot, discolor and darken in the processed process.

*No burr is allowed on the edge of the hole in the hole after drilling when machine processing. Milling is not easy, but stamping molding requires advanced mold and mold production. It is also very difficult for aluminum substrate.After stamping, the edges are very neat and no burrs. Do not encounter the welding layer on the edge of the plate.

* The aluminum base surface must not be scratched in the whole production process.The surface of aluminum is darkened by hand touching or by some chemicals, and customers do not accept. Therefore, the whole process of bumping or not touching the aluminum substrate is one of the difficulties in the production of aluminum substrate.
