OEM 22F Single-Sided Aluminum PCB Prototype 1.2mm Factory

single-sided aluminum pcbs are a smart choice when the circuit is straightforward but thermal stability is important. the aluminum base helps move heat away from the working area, improving long-term reliability and reducing hot spots in small enclosures. the “22f” and thickness details you provided point to a standardized build style that can be repeated consistently for both prototypes and volume orders.

as a Dongguan, China pcb manufacturing factory, we manufacture bare aluminum substrate boards with disciplined control over the fundamentals: stable dielectric thickness for predictable thermal transfer, flatness control for mechanical fit, clean solder mask definition, and reliable drilling/plating when holes are required. copper thickness such as 35um can be maintained for consistent conductivity, and surface finish options like HASL or ENIG can be selected based on cost, storage, and solderability needs. for oem b2b programs, we also support panelization guidance, 100% electrical testing, and protective packaging to keep boards clean, flat, and ready for downstream manufacturing.
