There is high requirements for the shape of aluminum entry board for PCB drill. It is a difficult problem needing to be solved in the production of aluminum drilling entry board. The shape processing methods of aluminum sheet for PCB are: milling, V-cut, shearing and punching.1. Milling. It is suitable for the processing of the sample of aluminum PCB sheet. Ordinary milling cutters can be used, but the speed is slower than milling FR4 circuit boards. During the milling process, it generates a lot of heat. If necessary, add a little water to the surface of the board.2. V-cut. Each unit (single board) can be arranged closer when designing the panel to make full use of the space of aluminum base plate. V-Cut requires a special V-Cut knife for aluminum and the speed should be low. V-Cut knife angles are 30, 45 and 60 degree.3. Shearing. It is applicable to make square or rectangular shape, but the shape tolerance of the shear is large, so it is not suitable for those aluminium entry boards with trict shape tolerance requirements.4. Punching. It is the most commonly used processing method for the mass production of aluminum PCB sheet. It requires to correct the punching die and the die is made of special die steel.After punching the shape, the warpage of the circuit board is very strict, usually 0.5%, and some customers require 0.2% or even 0.15%. The aluminum base plate is absolutely not allowed to be concave, because only the aluminum sheet surface is slightly convex, the heat can only be dissipated.There are also many requirements in this processing such as small punching hole diameter tolerance. Making a qualified die is also very important for making quality aluminum PCB board. These no only require the technologies, but also needs the rich experience of the workers. Haomei is a professional manufacturer of aluminum sheet with 30 years experience, so we can provide you best aluminum drilling entry board.

Both the aluminum substrate and the copper substrate are of excellent heat dissipation performance when used for making PCB entry sheets. But due to the difference in the nature of the two metals, the performance of the aluminum substrate and the copper substrate is different under the same conditions, and the thermal conductivity of the copper substrate is higher than aluminum drilling entry sheet.Thermal conductivity difference between copper substrate and aluminum substrate: Copper substrate: about 400 W / M.KAluminum entry board: 200 W / M.KThe difference of copper substrate and aluminum entry sheet in processability:1. The metal base can get a fine pattern by etching the circuit. Copper substrate can be processed into a convex shape, and the components can be directly pasted on the convex surface, realizing heat dissipation effect.2. Due to the PCB processing technology itself, metallization cannot be directly realized on the aluminum base surface (such as a single aluminum substrate), and the copper base can be processed into metallized holes, so that the corresponding single panel or multi-layer copper substrate has excellent grounding performance.Since copper itself can be welded, so that the final installation of the designed structural parts can be welded,which has better heat dissipation.3. Due to the difference in the elastic modulus of copper and aluminum (the elastic modulus of copper is about 121000MPa, the elastic modulus of aluminum is 72000MPa), the corresponding warpage and expansion and contraction of the copper substrate will be smaller than that of the aluminum substrate, and the overall performance is more stable.With the increasing density of PCB electronic components and the density of integrated circuits, the speed of signal transmission is accelerating. The corresponding power consumption also increases accordingly.In the future era led by 5G networks, radio frequency signals require excellent grounding performance, and heat dissipation requirements will also be greatly improved. The performance of ordinary rigid PCB boards will not meet their requirements. The demand for aluminum drilling entry board and copper substrates will be larger.Although copper substrate has better performance, aluminum PCB sheet is more easily accepted by the public and has broader application prospect in terms of processing cost.
