Product Description

LED Pcb Board Aluminum Base 1.0mm 1.2m 1.5m Circuit Board Mcpcb


•  Thick Copper Foil Etching


Aluminum PCBs are usually applied in power devices with high power density so copper foil is relatively thick. When copper foil is 3oz thick or more, copper foil etching requires trace width compensation. Otherwise, trace width will be out of tolerance after etching. Therefore, to guarantee optimal trace width/spacing and impedance control that are able to meet design demands, the following work has to be finished in advance.
a. Trace width compensation should be appropriately designed.
b. The effect of trace manufacturing on trace width/spacing should be eliminated.
c. Etching factors and agent parameters should be rigorously controlled.


•  Solder Mask Printing


Solder mask printing is regarded as a manufacturing difficulty of aluminum PCB fabrication due to effect of thick copper foil. If trace copper thickness is extraordinary after image etching, a large difference will be generated between trace surface and base board and solder mask will become difficult. To ensure smooth solder mask printing, the following principles should be conformed to:
a. Solder mask oil should be picked up with high-quality performance.
b. Two-time solder mask printing is used.
c. When necessary, the manufacturing method of resin filling first and solder mask second is relied on.


•  Mechanical Manufacturing


Mechanical manufacturing of aluminum PCBs contain mechanical drilling, milling and molding and v-scoring and burr tends to be left on internal via, which will reduce electric strength. Therefore, to ensure high-quality mechanical manufacturing, the following principles should be stuck to:
a. Electric milling and professional milling cutter should be picked up for low-volume production.
b. Control technique and pattern should be noticed in the process of die molding.
c. Drilling parameters should be appropriately adjusted on thick-copper aluminum PCBs to prevent burr from generating.
