PCB Board manufacturing can be a very complex or detailed process. Each stage of circuit board assembly needs to be performed in the correct order to ensure maximum efficiency and continuous function of the pcb board.

This will not change when outsourcing the circuit board assembly to the circuit board proofing manufacturer. Moreover, before starting to manufacture printed circuit boards,

Here are some PCB Board manufacturing tips to ensure that everything goes smoothly.

  1. Plan ahead: Before starting to send any PCB design to a reliable circuit board proofing manufacturer, make sure you have planned all aspects of the ordered design. This includes:
  • contacting the PCB manufacturer and
  • explaining the assembly time.

Some printed circuit board manufactures provide a general delivery time of 5 days or less, which is 75% faster than the pcb industry average production capacity.

  1. Triple check design:to ensure that the design meets the standards of the final product. A PCB Board manufacturingshould include multiple rounds of modifications to ensure that the design meets the requirements. For example, a printed circuit board with a complex design and a large number of through holes for high-tech products are important.
  2. Full label design:Even if the design has been checked many times before being sent to the circuit board proofing manufacturer, it may accidentally forget the correct label. Similarly, ensure that all components are properly labeled to reduce misinformation.
  3. Keep in touch:keep in touch with manufacturing partners throughout the PCB manufacturing process. This ensures that something in the design needs to be changed. And the manufacturer can be notified quickly.

Furthermore, communication is an important part of the entire process and can help ensure satisfaction with the final product.

ways to assemble DIY circuit boards for projects- PCB Board manufacturing

There are several different ways to assemble DIY circuit boards for projects. Each of which has its own advantages and disadvantages. Punch cards and other similar products can be used for PCB Board manufacturing projects. That do not require a professional look, and breadboard models Suitable for building prototype circuits.

When a project requires a more professional look, it is also possible to make printed circuit boards with your own hands from:

  • suitable materials
  • proper equipment.

Generally, the best way to build this type of circuit board with your own hands is to print the design on the workpiece using a laser printer. Which is onto a piece of copper workpiece. And then etch the workpiece with a solution of iron chloride. Similar results can be achieved with a finished PCB, if any.

Why designing is important in PCB Board manufacturing?

Pcb board manufacturers design Printed circuit boards to provide electrical communications and support for electronic components. Simultaneously, usually they use copper to electrically connect the components. And they also use several non-conductive substrates.

Commercially made printed circuit boards are usually etched. Although some are created by adding copper tracks to a non-conductive substrate. There are several ways of PCB Board manufacturing:

 It includes a method that can lead to engraved boards that have a pretty professional look.

To make a better printed circuit board with your own hands, you should consider a specific project. The easiest option for constructing the circuits yourself is simply to use a commercial “layout”. Since these devices are designed to quickly prototype new circuits.

Punch cards are another option that allows you to quickly mount the cards yourself, although the results usually do not have a professional appearance.

One way to make a professional-looking PCB with your own hands is to use a ready-made PCB. This is usually a computer numerical control (CNC) device that uses automatic design instructions (CAD) to automatically change the circuit on a piece of copper billet. Similarly, if the PCB mill is not available, you can also use the pickling process to maintain a PCB Board manufacturing process.

The importance of etching in PCB Board manufacturing


Materials and equipment needed for etching a printed circuit board with your own hands include:

  • a laser printer
  • glossy paper
  • Iron
  • copper blanks and
  • a solution of iron chloride.

This process involves printing a mirror image of the circuit. And transferring it to a piece of copper billet with heat from iron. Then the paper can be removed with water. And you can place the copper billet in a solution of iron (III) chloride. It will take place on the surface smoothly.

One of the important tips for maintaining this type of PCB Board manufacturing is to look for glossy paper that is not waterproof. Magazine paper is usually a good choice. Since magazines are usually printed with ink instead of toner.

Analysis of PCB circuit board wiring skills


PCB is also known as a printed circuit board. Which can realize the circuit connection and function realization between electronic components. And is also an important part of the power circuit design in PCB Board manufacturing.

The general principle of multi-layer PCB circuit board layout and wiring are as follows:

PCB Board manufacturing rules for setting the distance between printed traces of components

The spacing constraint between different networks is determined by the:

  • electrical insulation
  • manufacturing process, and
  • Componentspacing of printed traces for components.
  • Size and other factors.

For example, the pin spacing of a chip component is 8mil. The Clearance Constraint of the chip cannot be set to 10mil. And the PCB designer needs to set a 6mil PCB design rule for the chip separately. Furthermore, at the same time, the setting of the distance should also take into account the production capacity of the manufacturer.

In addition, an important factor that affects components is electrical insulation. If the potential difference between two components or the network is large, pcb board manufacturer should consider electrical insulation.

In PCB Board manufacturing the gap safety voltage in a general environment is 200V / mm. Which is 5.08V / mil. Therefore, when there are both high-voltage circuits and low-voltage circuits on the same circuit board, it is necessary to pay special attention to the sufficient safety distance.

When there are high-voltage circuits and low-voltage circuits, it is necessary to pay special attention to the sufficient safety distance.

Anti-interference and electromagnetic shielding of printed wires in PCB Board manufacturing

The interference on the wire mainly includes the interference introduced between:

  • the wires
  • the interference introduced by the power cord
  • the anti-interference and
  • electromagnetic shielding of the printed wires.
The interference on the wire mainly includes the interference introduced:
  • between the wires
  • the crosstalk between the signal lines, and
  • the crosstalk between the signal lines.

The reasonable arrangement and layout of wiring and grounding methods can effectively reduce the source of interference. And make the PCB design the circuit board has better electromagnetic compatibility performance.

In PCB Board manufacturing, for high-frequency or other important signal lines, such as:

  • clock signal lines
  • on the one hand the traces should be as wide as possible, and
  • for high-frequency or other important signal lines,

How to maintain corner alignment in PCB Board manufacturing?

The choice of line corner alignment

In order to make PCB Board manufacturing process easy and beautiful, it is necessary to set the corner mode of the circuit. And the choice of the form of the corner routing of the circuit during PCB design. You can choose 45, 90 and arc.

Generally, sharp corners are not used, and it is better to use arc transition or 45 transition. And avoid 90 or more sharp corner transition. The connection between the wire and the pad should also be as smooth as possible to avoid the appearance of small pointed feet. Which can be solved by the method of supplementing teardrops.

When the center distance between the pads is less than the outer diameter D of a pad, the width of the wire can be the same as the diameter of the pad. If the center distance between the pads is greater than D, the width of the wire should not be greater than the pad diameter.


When the wire passes between the two pads and does not communicate with it, it should maintain a maximum and equal spacing with them. Similarly, when the wire and the wire of the wire pass between the two pads without communicating with it, it should maintain the maximum with them.

And the equal spacing, the spacing between them should also be even and equal and keep the maximum. The spacing between them should also be uniform and equal and keep the maximum.

Conclusion- PCB Board manufacturing

The above is the general principle of PCB Board manufacturing layout and wiring. But in actual operation, the layout and wiring of components is still a very flexible work. The layout and wiring of components are not unique. And the results of layout and wiring are very to a large extent still depends on the experience and ideas of PCB designers.

It can be said that there is no standard to judge the right and wrong of the layout and wiring scheme. Only the relative advantages and disadvantages can be compared. Therefore, the above layout and wiring are only for PCB design reference, and practice is the only criterion for judging the merits.
