ZF Electronics, As One Of The Top Pcb Assembly Supplier In China, Can Provide Customers With Single-sided PCB, Double-sided FR4 PCB, Metal Core PCB, Heavy Copper PCB, Rigid PCB And Rigid-flex PCB. It Provide Pcb Board, Single Layer Pcb, Multi Layer Board, Rigid Flex Pcb, Aluminum Pcb,etc.

PCBs Are Usually Bonded To A Layer Of Copper Foil On A Glass Epoxy Substrate, The Thickness Of Which Is Usually 18µm, 35µm, 55µm And 70µm.

The Most Commonly Used Thickness Of Copper Foil Is 35µm. The Use Of That In China Is Generally From 35 To 50µm While There Are Also Thinner Ones Than This Such As 10µm And 18µm And Thicker Ones Than This Such As 70µm. The Thickness Of Copper Foil On 1 ~ 3mm Thick Substrate Is About 35µm; That On Less 1 Mm 18µm And That More Than 5mm 55µm.

If The Thickness Of The Copper Foil On The PCB Is 35µm And The Conductor Width Is 1mm, Then Its Resistance Value Is About 5mO And Its Inductance Is About 4nH For Every 10mm Length. When The Di/dt Of The Digital Integrated Circuit Chip On The PCB Is 6mA/ns With The 30mA Working Current, The Resistance And Inductance Contained In Each 10mm Printed Line Which Are Used To Estimate The Noise Voltage Generated By Each Part Of The Circuit Are Relatively 0.15mV And 24mV.
