FR-4 is the code name for a flame-resistant material grade. It represents a material specification that the resin material must be able to self-extinguish after burning. It is not a material name, but a material grade. It is based on the so-called A composite material made of Tera-Function epoxy resin plus filler and glass fiber.
Main technical features and applications: stable electrical insulation performance, good flatness, smooth surface, no pits, standard thickness tolerance, suitable for products with high performance electronic insulation requirements. FR-4 base material is a low-cost material. It has excellent mechanical performance and excellent processability, making it very popular among low- and medium-cost electronic product manufacturers around the world.
Note:
1: If you have your own design files:---In order to provide you with the most effective and accurate quotation for manufacturing the equipment you need, we hope you can provide us with the following information:
*Gerber files, PCB files, Eagle files or CAD files are acceptable
*Detailed Bill of Materials (BOM)
*Required quantity and your desired lead time
*PCBA testing methods ensure 100% high-quality products.
*If functional testing is required, a schematic file of PCB design is required.
*CAD files for shell manufacturing (if required)
*Complete wiring and assembly diagrams, with instructions showing any special assembly if required
2: If you don’t have your own gerber file and BOM, then we can also provide reverse engineering, if you can send us your prototype sample, when we receive your sample, we can start our reverse engineering work, After that, we can get the correct gerber&BOM
