Cheerise Circuits supports aluminum and metal-core PCB projects for lighting, power electronics, thermal-management assemblies, prototypes, and production orders. Our published metal-core PCB capability covers normal aluminum PCB, COB MCPCB, and copper-base board structures. Final material choice, stack-up, manufacturability, and schedule are confirmed from the project data.

These figures are a capability reference. The applicable build is confirmed according to the board structure, copper requirement, design geometry, surface finish, testing needs, quantity, and end-use conditions.
What to Include in an Aluminum PCB RFQ
Clear production inputs help the engineering team evaluate the correct process route and prepare a practical quotation. Please provide:
- Gerber RS-274X files and required quantity
- Board outline, finished thickness, copper weight, and any slot or cut-out requirements
- Aluminum, metal-core, or copper-base preference where specified by the design
- Surface finish, solder mask, marking, panelization, and packaging requirements
- Thermal, assembly, inspection, testing, or delivery requirements relevant to the project
For an assembly project, please also include the BOM, pick-and-place data, assembly drawing, and test requirements.
Engineering Review Before Production
Metal-core PCB manufacturing depends on more than a board outline. Before release, the project should be reviewed for the finished thickness, copper construction, feature spacing, drilling and routing requirements, surface finish, panelization, and inspection scope. When a design approaches a process limit or needs a special control, Cheerise Circuits confirms the feasible manufacturing route with the quotation.
Quality and Process Support
Our published capability includes in-process inspection during drilling, plating, etching, and solder-mask stages, together with final electrical testing where applicable. AOI and manual visual inspection provide additional checks based on the project and acceptance requirements. See our PCB quality and manufacturing capability page for the full published capability table and process overview.
