What are the two sides of a PCB called?

(2) The Double-layer PCB is a circuit board with copper on both sides, usually called one side as the Top Layer and the other side as the Bottom Layer. Generally, the top layer is used as the component surface, and the bottom layer is used as the component soldering surface.

How do you make a double sided PCB?

Flatcam setup

1. Go to Tools>Double-Sided PCB Tool.
2. Add the location of the holes: Point/box: (0,0) Alignment holes: (5,0),(145,0) Dril diam: 3.
3. Click Create alignment drill.
4. Go back to the Project tab: a file called Alignment Drills has been created.

What is 2 layer PCB?

1 Layer PCB has only one layer of conductive material and is suitable for low density and simple design. 2 Layer PCB contains 2 layers and layout is easier for more traces. The 2-layer PCB provides more surface area for housing a conductor pattern. Its surface is two times larger than that of a 1 layer PCB.

Why are PCB green?

It is due to the solder mask, which protects the copper circuits printed on the fibre glass core to prevent short circuits, soldering errors, etc. The colour of the solder mask gives the board its appearance.

How is PCB designed?

What is PCB design? Printed circuit board (PCB) design brings your electronic circuits to life in the physical form. Using layout software, the PCB design process combines component placement and routeing to define electrical connectivity on a manufactured circuit board.

How vias are made PCB?

How Are Vias Made? Unless you are at home with a DIY via rivet gun on a 2-layer board, vias are created during the PCB manufacture process. Briefly, holes are drilled through copper pads on the PCB, a chemical is put in the hole to dissolve epoxy on the internal layers to further expose the interior layer copper pads.

What are vias in double sided PCB?

A via (Latin for path or way) is an electrical connection between copper layers in a printed circuit board. Essentially a via is a small drilled hole that goes through two or more adjacent layers; the hole is plated with copper that forms electrical connection through the insulation that separates the copper layers.

How do you Desolder an old PCB?

12 Easy Tips to Improve Your PCB Desoldering Today

1. Keep Your Soldering Iron Tip Clean and Tinned For Effective Heat Conduction.
2. Match Solder Wick Width to Solder Joint or Contact Pad.
3. Clip Used Desoldering Wick after Every Use.
4. Avoid the #1 Rookie Mistake: Lift Up Iron and Braid at The Same Time.

What is 2 layer and 4 layer PCB?

2 layers PCB has two sided traces with a top and bottom layer, while 4 layers PCB has 4 layers. If you have a better understanding of two types of PCB boards, you will find that there are many differences in how they are constructed and how to work.

How many layers should my PCB have?

Most main boards have between 4 and 8 layers, but PCBs with almost 100 layers can be made. Large super computers often contain boards with extremely many layers, but since it is becoming more efficient to replace such computers with clusters of ordinary PCs, PCBs with a very high layer count are less and less used.

What kind of plating is used for PCB?

PCB in the production process , in order to meet the requirements of the board , the need to use a variety of surface coating process , such as: hole metal , copper, nickel , gold, electroless nickel, electroless gold plating , organic flux protective film and electroplating tin-based alloys.

What is the surface treatment process for PCB?

Surface treatment process involved in the production of PCB degreasing , to stain the inner wall of the hole , the activation treatment , electroless copper plating , direct plating process , plating tin alloy , copper etching , plating, gold processes.

How big is the PCB plating industry in China?

2000 China’s PCB production value of $ 3.635 billion , accounting for 8.7 % of global PCB output value , ranking fourth in the world . In China ‘s PCB output value , accounting for 83.5 percent of Guangdong . Therefore , the Guangdong region PCB plating is a great industry .

Why is acid copper plating used in board shop?

To meet these specification requirements, the board shop is forced to seek new and advanced processes in every department in the manufacturing line. Acid copper plating comes under heavy scrutiny, as it is the process that forms the traces and the through-hole connectivity that convey the signal from end to end of the final device.
