An unbelievably simple approach to order from us.
Just two steps from you
Step #1: You- Send Gerbers with quantity, specifications, destination, etc. View details
Step #3: You- Confirm your order and pay. View payment term
All in advance (preferred, it will save bank charges)
30% deposit and balance before delivery against pcb reports and photos of bare pcb, packages and packing list (OK). View reports and photos format
Step #4: We- PCB layout check and fabrication. View engineering query format
Step #5: We- Reports of fabrication status. View fabrication reports format
Step #6: We- Deliver and send you delivery note. View delivery note format
FR4 PCB starts out as a thin, non-conducting sheet of glass fiber epoxy laminate material. A thin layer of copper is then chemically deposited on each side of this material. Fiberglass is one of Copper Clad Laminate (CCL) raw materials, and be made from glass fiber yarn. Its cost is about 40% of the cost of CCL (thick) and 25% (thin plate) ofglass fibercircuit board.FR-4, is a widely acceptable international grade desination for fiberglass reinforced epoxy laminated that are flame retardant (self extinguishing). Printed circuit board using FR4 as core material will be named as "FR4 PCB".
Rigid FR4 PCB: Only FR4, it is rigid for whole board;
Rigid-flex PCB: Rigid FR4 plus flexible circuits;
Normal Tg FR4 PCB: 130, 135, 140 centigrade
Medium Tg FR4 PCB: temperature 150
High Tg FR4 PCB: Value 170, 180;
Normal: < 300 Mhz
High Radio Frequency: 300MHz ~ 3GHz,or even bigger
Extra Thin: 0.10~0.30mm;
In a word, according to different standard, FR4 PCB can be divided into different classifications. Please contact us for more information about the glass filber circuit boards.
