Rapid PCB Prototyping
What Is Rapid PCB Prototyping?
Rapid PCB prototyping is the pre-production of printed circuit boards before mass production, usually requiring PCB prototype manufacturers to quickly produce 5 to 100 pieces to help speed up the design and testing process. It is mainly used for electronic engineers to deliver the designed PCB files and BOM to the manufacturer after they have completed the circuit board. It needs to be analyzed from multiple perspectives to ensure that there is no delay in the project cycle and reduce the risk of product release.
What Are the Benefits of A Rapid PCB Prototyping?

How to provide documents for rapid PCB prototyping
What should be noticed in the rapid pcb prototyping documentation?
- File format: Normally need to provide Altium/Gerber/Eagle files. For the Gerber file, (for now we only accept RS-274-X format), double layers are shown below:
GTL- top copper layer
GBL- bottom copper layer
GTS- top solder mask layer
GBS- bottom solder mask layer
GTO- top overlay layer
GBO- bottom overlay layer
DRL -drill layer
GM1- mechanical 1
GKO- keep-out layer
4 layers need the extra layer order, eg:
TOP-VCC-GND-BOT 、TOP-GP1-GP2-BOT、 TOP-G1-G2-BOT、 art001-art002-art003-art004
- PCB parameters: there are general the number of layers, material, thickness, surface finish, color of solder mask, copper thickness, and other specific requirements, the following to understand the main parameters of this part.
Materials:It is best to consult in advance to explain what kind of materials are required for the manufacture of rapid PCB prototyping. At present, the most common material is FR4, FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios.
Layers:The price of PCB board varies with the number of layers
Solder Mask: There are many colors about rapid PCB prototyping, green, black, white, blue, red, yellow, matt black and matt green (We support all of the above color). It is worth mentioning that considering efficiency and cost, UETPCBA regards green as a conventional color.
Silkscreen: The silkscreens printed on the PCB is usually matched with the solder mask color.
Copper:Generally according to the current of PCB circuit to scientific calculation of the thickness of copper, generally the thicker the better, but the cost will be higher, so it needs a reasonable balance (we support 1 to 10oz).
Via Process:Tenting vias, Plugged vias and Vias not covered
Surface Finish:Currently we support Electroless Nickel Immersion Gold (ENIG), Hot Air Solder Level (HASL, Lead and Lead‐free), OSP, Immersion Tin, Immersion Silver, ENEPIG Gold Fingers, Flash Gold, Full Body Hard Gold, Wire Bondable Gold, etc.
Quantity: The number of PCB prototypes to be made must be clearly stated.
Other Special Requirements: if there are any other special requirements for PCB manufacturing, you should also inform to your PCB manufacturer, like impedance control, custom stack-up and other special production process.
