What is Single-Sided PCB?
Base Material: The base materials used in Single Sided PCBs are FR4, CEM-1, CEM-3 (FR1/XPC,).
Thickness: 0.4 mm to 3.2 mm
Copper Weight: 1 to 2 oz/ft² minimum
Lines and Spaces: low cost 200um, minimum 100um
Layer Count: 1
Surface Finish: LF HASL, OSP, Im Tin, Im Silver, ENIG. (Recommended LF HASL or OSP due to price.))
Solder Mask: Green, White, Black, Blue, Red, Yellow.
Single-Sided PCB Materials
CEM-1 is a composite material composed of woven glass fabric and a paper core combined with epoxy resin. With the properties of easy punching, excellent electrical properties, and higher flexible strength, the CEM-1 provides excellent mechanical and electrical properties and punches well up to 2.36 mm (0.093″).
The CEM-3 is very similar to FR4 but instead of woven glass fabric throughout, a composite of a non-woven glass core and a woven glass surface is used. CEM-3 has a milky white color and is very smooth. It is a complete replacement for FR4 and has a very large market share in Asia. It is a type of flame-retardant epoxy, copper-clad, plate glass material, and is generally used in electronics for double sided-PCB boards.
