4 Layer Prototype Multilayer PCB Stackup and Manufacturing

4 Layer Prototype Multilayer PCB More layers it is, more complex & difficult the manufacturing will be, and more expensive the cost will be. The lead time of multi-layer PCB is different from normal one, please contact us for a exact lead time.

Structure of Multi-Layer PCB

• Top silkscreen/Legend: to identify name of each PAD, board part number, data, etc;
• Top Surface finishing: to protect exposed copper from oxidation ;
• Top Soldermask (overlay): to protect the copper from oxidation, to be not soldered during SMT process;
• Top Trace: copper etched according to design to carry on different function
• Substrate/Core material: Non-conductive such as FR4, FR5
• Prepreg (PP)
• Middle Layers, such as GND, VCC, Inner 3, Inner 4, etc.
• Prepreg (PP)
• Bottom trace (if any): (same as above mentioned)
• Bottom soldermask (overlay):(same as above mentioned)
• Bottom surface finishing: (same as above mentioned)
• Bottom silkscreen/legend: (same as above mentioned)

• Microsection report and Tin testing board are put together with PCB in cartons.COC (Certificate of Conformity)  will be sent to customer by email in PDF.
• Several layers of thick EPE(Expand aple poly ephylene) are filled fully in gaps between PCBs and cartons. Thickness of 1 layer EPE is 10mm.
• Neutral Packing is adopted if no special requirements. Strong and thick cartons(Thickness:10mm,7 layers). Different sizes of cartons are designed to meet demand of different PCB size. All package are within weight limit of cartons. For mass production order, no exceed 21kg per carton normally.
• All cartons sealed with strong adhesive tape should be sealed twice so as to make them more durable.
• Solid PP/PET strapping is used outside of cartons. 
• Shipping mark, fragile mark and postcode label are all pasted clearly.
