Before going ahead and placing order for a high volume PCB for the next circuit design, it is wise on the part of electronic manufacturers and businesses to first order a prototype or a small batch of PCB. The purpose behind doing so is to make those prototypes or samples go through testing in order to detect any potential errors which may hinder or interrupt the production during the final stage.

This is what the PCB prototype method of manufacturing is all about. It tests the product beforehand to give the makers an assurance that they won’t be out of huge finances, in case something goes wrong during final phase of production and manufacturing. Any technical trouble or problems with the schematics during the end phase can cost huge finances, especially if the assembly is going to take place in-house.  That is why companies prefer to outsource prototyping to specialized companies before ordering larger volumes of circuit boards.
