Making a PCB is a complex process involving many steps. Here, we will introduce you to the entire PCB manufacturing process at our factory.

The publication is available on the https://www.wellpcb.com/special/pcb-fabrication-process.html section of the company’s website for free.

Among the key subjects on PCB Fabrication Process include:

1. PCB Design and Layout: This section outlines the precautions for PCB layout, precautions before PCB fabrication, and an introduction to pre-production engineering.

2.Production Prepare: This section briefly introduces the production preparation process, including Cut Lamination and Drying.

3.Inner Layer:

(1) Inner Layer Imaging: This section briefly describes the Inner Layer Imaging consisting of three steps: Inner Film, Inner Exposure, and Inner Layer Development.

(2) Inner Layer Etching: This section briefly describes the Inner Layer Etching consisting of two steps of etching and unloading the film.

(3) Inner Layer AOI:

This section briefly describes Inner Layer AOI is an automatic optical inspection,

To check whether the core plate after etching has an open or short circuit, and the print is clean or not.

4.Lamination:

This section mainly introduces the definition of Lamination.

1. Drilling: This section introduces mostly Drilling.

6.Electroless copper deposition: This section describes the copper primarily in the base plate, and the copper in the hole can be thickened to 5-8um by electron transfer reaction.

7.Horizontal Electrolytic Plating: This section focuses on the copper in the base plate, and the copper in the hole can be thickened to 5-8um by electron transfer reaction.

8.Outer Layer Imaging: This section mainly describes the Outer Layer Imaging consisting of three steps: Outer Layer Film, Outer Layer Exposure, and Outer layer development.

9. Graphic Plating: This section focuses on the three levels of Graphic Plating, which consists of thick copper plating, tin plating, and film removal.

10.Outer Layer Etching: This section mainly describes the composition of Outer Layer Etching.

11.Solder Mask: This section briefly describes the role of the Solder Mask.

12.Silkscreen: This section briefly introduces Silkscreen.

13.Surface Finish: This section briefly describes the part of surface treatment.

14.Profile: This section describes the engineering department to create a shape program based on the border provided by the customer.

15. Other Surface Finishing Process: This section focuses on the two processes of the Other Surface Finishing Process are V-CUT and Gold Finger.

16.Electrical Testing: This section focuses on the role of Basic electrical reliability testing and the introduction of Flying Probe Testing.

17.Final Visual Inspection (FQA, FQC): This section mainly describes Final Visual Inspection (FQA, FQC) by professional quality control group for testing.

18.Package&Delivery: This section describes mostly the PCB packaging method and delivery time.

Besides, The focus of this article is Let you know more about the details of the PCB manufacturing steps and how to solve them.
