How to choose PCB thickness
Printing circuit board (PCB) is the basis of most electronic products. The PCB structure is simple. The most common connection of PCB is computer hardware. However, it is also used for radio, TV, mobile phone, etc. The performance of PCB depends on various factors, such as manufacturing materials, costs, manufacturing, prototypes, etc.
In addition, PCB thickness also has a very important impact on the overall performance and durability, which affects the resistance and conductivity of PCB; therefore, it is necessary to work in perfect thickness. Whenever we talk about "standard" features or some projects, we talk about the characteristics of "standards" or some projects. When the benchmark is measured, we refer to the perfect feature we want to achieve. Therefore, our products have undergone and passed all performance, weight, durability, reliability and the most important quality testing.
PCB slices: PCB sheets do not have a fixed standard thickness measurement value; however, market value and preferences determine the standard PCB thickness is still the most commonly used. In order to obtain a larger thickness, a series of pre -immersion plates and various core materials can be combined.
What is the standard PCB thickness?
The current standard PCB thickness is within the following range: 0.031 inches (0.78 mm), 0.062 inches (1.57 mm) and 0.093 inches (2.36 mm). However, the most commonly used thickness is 157 mm or 0.063 inches. But it should also be remembered that users or applications also determine the thickness standard of the circuit board. Initially, the plywood was used as a substrate, and the thickness was greater. With progress, better choices, such as epoxy resin.
The most important and most common metals in PCB functions and applications are copper. This is because the thickness of the standard board is relatively smooth using copper, which is about one ounce (OZ). In addition, a very thin PCB thickness limits available surface treatment options.
There are various factors that are manufactured and design specifications and need attention; some of them are: design factors that affect and affect the thickness of PCB:
1) Major cost factors: determined by the following factors: circuit board size and number of layers
2) PCB complexity: number of layers, holes
3) Materials used: The selection of materials is based on: operating speed, frequency, work temperature (highest)
4) Operating environment: manufacturing factors, the size and quantity of the hole that affects the thickness of PCB, the number and quantity of the hole, the copper thickness, and the surface treatment
The width calculator is used to specify the PCB thickness. Its function is similar to ordinary calculators; you need to enter all details and specifications, and the calculator will provide you with the required thickness. In order to make accurate and effective judgments, the calculator provides up to one percent of a millimeter computing power. However, if the application requirements should be kept under a measurement value.
Factors that remember when choosing PCB
The following is the factors and specifications that need to be kept in mind when determining the thickness of the PCB board to obtain better durability and performance: weight, flexibility, impedance matching, required space components, compatibility compatibility
What if I want to customize thickness?
The board or panel used to make PCB is easy to buy in the market. There are many customized options that can provide design and thickness according to your specifications and needs. You can choose the thickness range from 0.2 mm to 6.3 mm, with an incremental amount of one mm. Further reading to understand the factors that must be supervised when selecting the thickness of the custom PCB board.
Factors to be remembered when customized PCB thickness
1) turnover time: Generally, due to the uncommon thickness specifications, the expected turnover time of the custom PCB layer thickness is received. This will affect your delivery plan and development time.
2) CM's device ability: If you don't want to compromise on your design and model, be careful when choosing your CM. If your CM selects limited devices to manufacture and design the typical PCB thickness you are looking for, you will have to compromise and modify your PCB layout.
3) Additional cost: Due to additional details and expectations, the customization cost is usually high. The use of specific materials, design, and obeying a detailed description is equivalent to an additional manufacturing cost compared to the usual price.
Using custom thickness can increase design attraction and output, providing them with unique performance and value. However, due to additional treatment, manufacturing steps and materials, multi -layers may be very expensive.
With the perfect manufacturing partner, you can successfully achieve the required thickness. The first step of customized is usually determining the common core pre -immersed thickness, and it perfectly combines it with copper plating, copper foil and welded layer.
