How to choose PCB thickness and what is the standard PCB thickness?

Printed circuit boards (PCBs) are the basis of most electronic products.PCBs have a simple structure and are most commonly associated with computer hardware. However, it is also used in radios, televisions, cell phones, etc. The performance of a PCB depends on a variety of factors, such as the material used to manufacture it, cost, fabrication, prototyping, and more.

In addition, the thickness of the PCB has a significant impact on the overall performance and durability, affecting the resistance and conductivity of the PCB; therefore, working with a perfect thickness is a must, and whenever we talk about "standard" features or benchmarks for certain items, we are referring to the perfect features we want to achieve. Therefore, our products have withstood and passed all performance, weight, durability, reliability and most importantly quality tests.

PCB Boards:There is no fixed standard thickness measurement for PCB boards; however, market values and preferences dictate that the standard PCB thickness is still the most commonly used thickness. For greater thicknesses, a range of prepregs and various core thicknesses can be combined.

What is the standard thickness of a printed circuit board?

Current standard PCB thicknesses are in the following ranges: 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 the user or application also determines the thickness of the board. Initially, plywood was used as a substrate, leading to greater thicknesses. As progress was made, better options emerged, such as epoxy.

PCB Copper Thickness

The most important and common metal used in PCB functions and applications is copper. The reason for this is that standard boards achieved with copper have a relatively smoother thickness of about one ounce (oz). In addition, very thin PCB thicknesses can limit the available finish options.

There are various manufacturing and design specifications and considerations, pcblink 1oz vs 2oz Copper some of which are: Design Considerations Affecting and Influencing PCB Thickness.

1) Significant Cost Factors: Determined by the following factors: Board size and number of layers.

2) PCB complexity: number of layers, number of vias

3) Materials used: Material selection is based on: operating speed, frequency and operating temperature (maximum).

4) Operating environment: manufacturing factors affecting PCB thickness, hole size and number, copper thickness and surface finish.

How to specify PCB thickness?

The Line Width Calculator is used to specify PCB thickness. It functions like a regular calculator; you enter all the details and specifications and the calculator gives you the thickness you need. To make an accurate and efficient determination, the calculator offers the ability to calculate up to one hundredth of a millimeter. However, if the application requires the thickness to stay below the measured value.

Factors to Consider When Selecting PCB Thickness

To improve durability and performance, the following factors and specifications must be considered when deciding on the thickness of a printed circuit board: weight, flexibility, impedance matching, required space components, compatibility

Design Requirements

What if I want to customize the thickness?

The boards or panels used to manufacture PCBs are readily available on the market. There are a variety of product customization service options available to develop a design and thickness according to your specifications and needs. You can make a selection of thicknesses ranging from 0.2 mm to 6.3 mm in increments of one hundredth of a millimeter. Read further to understand the factors that must be monitored more closely when choosing your own custom PCB board thickness.

Factors to keep in mind when customizing PCB thickness

1) Turnaround Time: Typically, the expected turnaround time for receiving custom PCB layer thicknesses is longer due to unusual thickness specifications. This can affect your delivery schedule and development time.how to test pcb board with a multimeter?

2)Configuration Management Device Capabilities: If you don't want to compromise on your design and modeling, be careful when selecting your configuration management. If your CM has a limited selection of equipment to fabricate and design the typical PCB thickness you are looking for, you will have to compromise and modify your PCB layout.

3) Additional Costs:Customization costs are usually high due to additional details and expectations. Using specific materials, designing and following a detailed set of instructions equates to incurring more manufacturing costs than the usual price.
