Aluminum PCB is the most common type of all Metal Core PCB (MCPCB) also known as IMS (Isolated Metal Substrate). Aluminum Board are a unique metal-based copper clad laminate excellent thermal conductivity, high mechanical strength and dimension stability.

PCB Plating for Chip on Board Assembly must be planned in advance to ensure manufacturability of the device. This planning begins with design rules and selecting the wire bond method to be used. Common wire bond materials include aluminum or gold wire.
Aluminum Wedge Wire Bonding and ENIG...
There are several techniques to minimize distortion including:
1. Proper PCB layout design
For example, keep analog and digital signal traces separate to avoid crosstalk and so on.
2. Design PCB traces with controlled impedance
3. Use a solid ground plane to provide a low-impedance return...
Countersink
A countersink is a cone shaped hole cut into the laminate. It is typically used to allow the tapered head of a screw to sit flush with the top of the laminate. By comparison, a counterbore makes a flat-bottomed hole and its sides are drilled straight down. This is usually used to...
Traces are used to connect the components, but how wide should the traces be?
The trace width for different nets depends on the below three possible factors:
1.Manufacturability:
Traces cannot be too thin,otherwise,the board will be unmanufacturable. The trace width need much larger than the...
Oscilloscopes are one of the most important tools used by electronic engineers. It is useful in multiple fields of studies, such as RF design, electronic circuit design, electronic manufacturing, servicing and repairing of electronic devices. Here are three important factors of an ideal...
Do you know how to choose the thickness of stencils?
If you do not know, just tell us your production requirements, we can provide the appropriate advice for you reference.
Stencil thickness should meet the minimum spacing QFP, BGA , taking into account the smallest chip components.
QFP...
What is a metal core PCB?
Metal Core PCBs are printed circuit boards that use copper or aluminum as a core material. The purpose of the metal is to divert this heat away from critical board components and towards less crucial areas such as the metal heatsink backing or metallic core.
Compared...
Trace width, the impedance trace width is inversely with the impedance value, the thinner the trace is, the larger the impedance value.
Space, not only the space between the impedance traces will affect the impedance value, but the ground copper around the impedance traces. Impedance traces...
