windoze killa Posted July 22, 2006 Report Share Posted July 22, 2006 Without going into deep detail FR4 is the fire retardent level. FR4 is the most common higher quality type. FR2 is used in cheaper consumer type products.The HASL is basically tinned tracks. The other 2 are electro deposited gold or silver coatings. Much more expensive.

trigger Posted July 25, 2006 Report Share Posted July 25, 2006 And these?Black FR4, FR5, CEM1, CEM3, PTFE, Polyimide, Mixed Builds, Aluminium Substrates, Copper Core PCB and PTH?Whats the Finished Copper Weight?They are the substrate or say the materials used inside the PCB.For finished copper weight, if you are working on RF, the thickness of copper will affect the dielectric coefficient of the PCB.
