Some Tips on PCB Design for Cheap Manufacturing

PCB Design for Cheap Manufacturing

The continuous development of electronic science and technology on the printed circuit board puts forward higher requirements, requiring designers to consider the manufacturability of printed circuit boards throughout the design.In the fierce competition in the electronics industry, almost all companies want to maximize the economic benefits. Therefore, low costs and high outputs in PCB manufacturing and assembly are essential to companies.

About 60%-75% of the manufacturing costs of the PCB or other products (quality of materials, production processing, product assembly, etc.) are determined by design decisions. So it makes the designs so important for your projects in a cost-effective way.
So there are some guidelines or tips which can be considered. For any designs for manufacturing, the important design principles or rules are to help the designer or developer reduce their cost or reduce the difficulty of manufacturing the PCB。 The following are some suggestions or tips for designers to make cost-effectively printed circuit boards.

Reduce the Amount of Parts

Reduction of the number of parts or components is a good chance for reducing the manufacturing cost, fewer parts means less purchases, processing time, assembly difficulty, testing, etc. It eases the processing process and at 90% it can reduce the assembly cost. In general, it reduces the intensity of all the processes involved in the processing of the final product.

Use Industry Standard Sizes & Components

We need to stick to industry-standard sizes and components. Essentially, it opens up the possibility of automation and makes everything simpler and more efficient. If our PCBs are designed to use standard dimensions, then PCB manufacturers will not have to use as many resources to manufacture boards with customized specifications.

Use Industry Standard Sizes & Components

This also applies to the components on the board. Surface mount components require less drilling than through holes, which makes these components perfect for cost and time savings.

Design for Ease Fabrication

Some designs have special requirements with many slots or v-cut lines, In general, excessive tolerance, surface-finish requirement, very small hole size, small track space, heavy copper weight, and so on are common problems that result in higher than necessary production costs. Take a look at the following example:Hole: normally 0.3mm is the standard hole size and a hole below 0.3mm will lead to higher cost. Any buried vias, blind vias, or half holes will also cause higher costs.Track space: The standard is 6/6mil, 5/5mil or below will increase the cost.Surface finish: HASL with lead is the cheapest. If made in immersion gold, it will have an extra cost of $22-$23.Solder mask color: green solder is the most commonly used color for PCB, therefore it is the cheapest, and other colors, like Matt black, red, and yellow will increase the cost.

Quality Materials

Cheaper materials will cost more money in the long run. Inferior materials create inferior products. Cheaper materials are also more likely to fail. Therefore, choosing high-quality materials is very important to the ability to save money in PCB manufacturing.

Optimized Layout

Optimizing the layout can help reduce manufacturing costs. Try to put components in a way that minimizes the amount of board space required and reduces the number of required vias. Also, try to group components in a way that reduces the length of the alignment.
Hopefully, the above information is helpful for those designers who are new and want to learn more about cost-effective PCB manufacturing.
