PCB Technical - What is the difference between PCB manufacturing and proofing?

PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.

Introduction to PCB proofing

In terms of quality assurance, the regular factory is definitely better than the model company. The model company is a one-shot deal and collects money when the sample is sent. You don't need to do the flying probe test. If the quality is not good, you have to call again and pay again; Regular factories generally do flying probe tests, and they are careful and professional from materials to processes, so the quality is often successful in one shot.

There are two ways of proofing: a regular PCB factory and a professional model company., They survive by charging for proofing, and will definitely accept your request for only two items.

The purpose of the formal factory proofing is to have bulk orders, so of course I hope to return the order; the proofing company itself only makes prototypes or small batches, and he can't do it if you have a large order for him.

There is a big difference between PCB manufacturing and proofing

Different prices

The price of PCB board and the price of proofing are different

Different uses

PCB manufacturing was discovered in 1946 as a physical phenomenon. It is mainly used in the fields of physics, chemistry and biology, and its main function is to carry out qualitative and quantitative research on materials and spatial positioning. In 1973, Lauterbur et al. first reported the imaging technique using the principle of magnetic resonance.

Proofing is a new diagnostic method that uses atomic nuclei to resonate in a magnetic field to generate magnetic resonance signals to build images. It is used to detect hydrogen proton density, hydrogen proton movement flow rate, T1 relaxation time, T2 relaxation time, and various scanning parameters. Can generate MRI signal and affect the intensity of MRI signal.

Different quality

In terms of quality assurance,PCB manufacturing must be a regular factory better than a prototype company, while the quality of proofing is relatively poor.
