Printed circuit boards or PCBs are the most commonly used method to electrically connect and mechanically support electronic components that use conductive routes, routes or signal traces. They are essentially made of insulation layers of one or more patterns of copper conductors. They are also known as printed circuit boards or PCB. They are used in almost all types of commercial electronic devices available in the market.
Some of the alternatives common to PCB include point-to-point construction and cable winding. These printed circuit boards must be designed and disposed of properly; Therefore they are expensive when they are made individually. However, when they are manufactured in large quantities, they can become considerably cheaper and faster to produce. The design and quality control requirements of the PCBs used in the electronics industry are determined by the IPC organization.
The manufacturing costs of printed circuit boards and PCB assembly are based on many factors that must be considered when designing them. Beginners in the field must learn how to optimize their project taking into account cost factors. There are many new designers who do not understand the meaning of spacing, basic width and other rules that greatly influence total manufacturing costs and the price per unit.
If you are a newbie in the field and want to reduce your manufacturing costs and tools, we recommend that you follow the guidelines outlined below:
Small plate size: When trying to reduce costs, you must be careful when choosing the right plate size for the circuit. A larger board size will obviously increase manufacturing costs. The cost of producing a unit is almost proportional to the area of cardboard used.
Board shapes: You should try to use only normal board shapes, such as rectangles and squares, because irregular shapes are more expensive. In addition, you should avoid using cutouts or internal slots unless it is very essential for scaling purposes. There are some PCB stores that can charge extra for irregularly shaped boards. Unless it is necessary for a specific project, we recommend that you choose square or rectangular forms of boarding to reduce costs.
Hole size: When making printed circuit boards, you must be sure to use the larger holes because small holes and annular rings mean higher costs. The reason is quite simple. Making smaller holes requires more precision and this increases the cost in several ways. There are many manufacturers that cost more if you need holes with a diameter less than 0.4 mm. As a general rule, you should talk to your manufacturer before deciding which hole size would be the most appropriate for the PCB.
Finally, the size and space between copper objects are important in determining the price of printed circuit boards. When the difference between the objects decreases, the price increases. This makes sense because a smaller space means greater precision and this increases overall manufacturing costs.
