PCB manufacturing and PCB Assembly Services
PCB manufacturing ：
PCB is a printed circuit board. A printed circuit board (PCB) is a covered sandwich design of conductive and insulating layers. PCB supports electronic parts of the circuit mechanically by utilizing conductive cushions in the shape designed to accept the component’s terminals and electrically connects them utilizing traces, planes, and different provisions scratched from at least one sheet layer of copper covered onto or potentially between sheet layers of a non-conductive substrate. Components are solder on PCB are electrically connected to each other and are mechanically working more efficiently. PCBs are generally used in all electronic products to connect different objects which are being used for the circuit.
PCBs can be single-sided (one copper layer), twofold-sided (two copper layers on the two sides of one substrate layer), or multi-layer (external and internal layers of copper, exchanging with layers of the substrate), 6 layer PCB manufacturing. Multi-layer PCBs take into account a lot higher part thickness because circuit traces on the inner layers would otherwise take up surface space between components. The rise in popularity of multi-layer PCBs with more than two, and particularly with more than four, copper planes was simultaneous with the reception of surface mount innovation and we also offer 6 layer PCB 製造. Notwithstanding, multi-layer PCBs make repair analysis and field adjustment of circuits substantially more troublesome and generally unfeasible.
A fundamental PCB comprises a level sheet of protecting material and a layer of copper foil, covered to the substrate. Synthetic scratching with chemicals divides the copper into independent leading lines called tracks or circuit traces. The tracks work as wires fixed set up, and are protected from one another via air and the board substrate material. The outer layer of a PCB might have a covering that shields the copper from erosion and lessens the odds of binding shorts between follows or undesired electrical contact with stray uncovered wires. This coating is called solder resist as it helps in preventing solder shorts.
The working of PCB is mostly dependent upon the design of PCB. It is a very important step to make your board work more efficiently.
At first, PCBs were planned physically by making a photomask on a clear mylar sheet, normally at two or multiple times the genuine size. Beginning from the schematic graph the part pin pads were spread out on the mylar and afterward, traces were directed to interface the pads. Rub-on dry exchanges of normal part impressions will increase its efficiency. Traces that have to be made on the board are drawn by sticky tapes.
But now modern PCBs are designed by using automatic software. This software is firstly used to draw a schematic diagram of a required circuit and then convert that diagram to a PCB layout. PCB CAM performs the following functions,
- Input of the fabrication data.
- Verification of the data
- Compensation for deviations in the manufacturing processes
- Output of the digital tools
Dimensions of the PCB board are selected according to the design of the PCB and the design of the machine in which it has to be placed. The position of the components is also decided according to the design of the product.
Two complimentary functions of PCB are,
1-The first is to fasten electronic parts in assigned areas on the external layers through soldering.
2-The second is to provide reliable electrical connections and also reliable open circuits between the terminals of the components in a controlled manner.
1- Design schematic diagram and convert it into PCB layout.
2- Print out your PCB layout on glossy paper.
3- Cut the copper plate according to the size of your print and components to be used in the circuit.
4- Rub your copper plate with any steel wool to remove the top oxide layer of copper as well as the photoresists layer.
5- Transfer the print from the paper to your PCB board by using iron as e iron heat melts ink printed on glossy paper and get transferred to copper plate.
6- Place the board in lukewarm water for 10 minutes and remove the paper gently.
Etching should be done very carefully so that solution does not harm your skin. This process is done by dissolving 2 or 3 spoons of ferric chloride in warm water and dipping the PCB board into it for at least 30 minutes. FeCl3 reacts with unmasked copper and removes an extra amount of copper from the PCB board. Now take it out with a holder as the solution is harmful to the skin.
The reaction of copper is given as:
Cu + FeCl3 = CuCl3 + Fe
Check your product if all extra copper is etched or not and repeat the step accordingly for 2,3 minutes.
8- Drill holes where needed and fix all the components according to the desired circuit.
Individuals deal with issues while making a circuit on a breadboard like a circuit might work sometimes and may not work other times.
Either connection is not proper or free or may get damaged while working or conveying the circuit on a breadboard.
PCB makes breadboard connections super durable.
