When you're looking for prototype PCB fabrication, it's important to work with PCB service providers who can quickly turn around your PCB design resources. These sample boards help you verify your design before you start full production, thus avoiding costly errors. Rocket PCB is a PCB manufacturer with fast response capability.
The circuit of double sided PCB & two layers PCB is in two sides of PCB board, and the circuit of double sided PCB board is connected by via in the middle. Double sided PCB is a very important PCB in the circuit boards, which is classified according to the number of layers. There are 4-layer boards, multi-layer boards, high-level multi-layer boards and so on. Of course, if classified according to the PCB application, PCB copper thickness and structure, it also includes double-sided antenna PCB, double-sided metal-base PCB (aluminum substrate / copper substrate / ceramic substrate), high TG double-sided board, thick copper PCB, high-frequency material double-sided PCB, double-sided flexible PCB board, etc.
Double-sided PCB from Rocket is very common in both PCB production and PCB prototype circuits allowing a higher density between components and it makes the layering of tracks an easier process. Compared to the multilayer PCB, double layer PCB do not need laminating but need plating in order to realize the function of vias.
It is widely used in high-tech industries, such as telecommunications, power supply, computer, industrial control, digital products, scientific and educational instruments, medical devices, automobiles, aerospace defense, etc.
Double sided PCB manufacturing flow
1, Cutting Material: Cut out easy-to-process dimensions from the whole sheet of copper clad laminate (CCL).
2, Drilling: Drilling a conductive hole or plug-in hole on the board according to the computer drilling program.
3, PTH: A thin layer of chemical copper is deposited in the drilled hole, with the aim of sinking a layer of copper through chemical methods in non-conductive epoxy glass cloth substrates (or other substrates), making it easy for the rear plating guide to form the circuit pattern;
4, Full Plate Copper Plating: The main purpose is to protect the thin layer of chemical copper from oxidation in the air, forming no copper or holes in the holes.
5, Circuits (graphics transfer) is pasted with dry film/wet film on board. After exposure and development, circuit graphics are made.
6, Pattern plating: Wire copper thickening plating on pattern circuit, so that the hole and pattern copper thickness reached a certain thickness, can load a certain amount of current
7, Etching: Fade The graphics ink or dry film, etching off the excess copper foil to obtain conductive line graphics. Remove the pattern ink or dry film, etch out the excess copper foil to get the conductive graphics
8, Remove tin: The tin layer on the formed graph is removed to reveal the required pattern
9, Silk screen soldermask or paste soldermask dry film: Printing a layer of soldermask ink on the board, or affixed with a layer of soldermask dry film, after exposure, development to form soldermask layer, the main purpose is to prevent short circuit between the lines at the time of soldering
10, Immersion Gold/HASL: Immersion gold or spray a layer of tin on the board where it needs to be welded, making it easy to solder, while also preventing oxidation of the copper surface at the place
11, Silkscreen: printing some iconic words on the board, mainly convenient for customers to install components
12, Routing: Process the profile of the Board
13, Electrical test: Detecting whether there is an open short circuit in the PCB by means of a closed loop
