Double sided Fast PCB PCB prototyping quick turn around PCB production
PCB model, the foremost normally surface treatment is HASL. At constant
time, OSP, gold plating, immersion gold, immersion silver, is equally
HASL- sensible appearance, simple to weld tin on the pad, easy welding, low price.
ENIG- stable quality, sometimes employed in the case of boding IC.
two sided board, using through hole within the middle connects
two-sided traces, and there are 2 more processes than single aspect
board, that is Electroless Copper and plating.
Double sided boards are wide used and relatively easy, each manufacturer can do, that the competition is usually on the price.
Some makers use low grade CCL, soldermask ink is also comparatively low cost, even the surface plating is skinny, leading to price variations.
At Rocket PCB, we have been using top-grade materials, never cut corners, quality is first-class, our strategy is tiny profits but fast turnover, therefore within the premise of quality assurance, our PCB price is extremely competitive, you're welcome to inquiry here to get quick quotation!

1, Cutting Material: Cut out easy-to-process dimensions from the whole sheet of copper clad laminate (CCL) with a certain thickness and foil thickness
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 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

Rocket PCB supply chain meticulously practices all-around quality management and actively introduces and implements multi-domain system management. We have successively obtained ISO9001, ISO14001, IATF16949, OHSAS18001, ISO/IEC27001, ISO13485 and AS9100 certifications.
Due to the circuit board industry manufacturing level is uneven, if accidentally selected to the low-end manufacturing plant, there will be poor engineering data processing, old equipment, management confusion, poor parameter control, improper operation of personnel and other process issues, such as the following quality defects.
