The processing method for printed board shapes involves milling, punching, “V” groove opening, and drilling, selected based on customer needs and batch size, with attention to cutting point selection and tube hole placement for efficiency and optimal shape processing.
Aluminum PCBs, renowned for their exceptional heat dissipation and durability, feature a metal core composed of copper foil, a thermally conductive insulating layer, and a metal substrate. They offer optimal heat dissipation, high current-carrying capacity, and robust electrical insulation, making them ideal for various applications without the need for radiators, thereby enhancing heat dissipation and maintaining superior performance.

Various methods such as drilling, winding, and wire crossovers are used to prevent cross circuits in printed circuits, while components can be installed vertically or horizontally with different hole spacing. The connection points of circuits at the same level should be close, and a hierarchical order must be followed for grounding arrangements to prevent interference and self-excitation. Strong current leads should be wide to reduce resistance and voltage drop, while high impedance wiring should be kept short to prevent instability.
Flexible circuit manufacturing involves fewer fabrication steps than rigid PCBs, including adhesive/seed finishing, adding copper foil, drilling, through-hole plating, etch-resist printing, etching and stripping, coverlay or covercoat, cutting out the flex, and component assembly. WellCircuits offers a comprehensive range of flexible PCB prototyping and assembly services, specializing in meeting high-quality and fast-paced demands in the electronics industry.
Cross circuits in printed circuits are prohibited; use “drilling” and “winding” techniques for potential crossings, and simplify complex designs when necessary, allowing wire connections. Components like resistors, diodes, and tubular capacitors can be installed vertically for space efficiency or horizontally for enhanced mechanical strength.
