1. 在薄板方面没有绝对标准。在电路板行业中，如果板的厚度低于0.6mm，就可以称为薄板://www.wellcircuits.com/wp-content/uploads/20230105/c66b7982-b419-11ee-9621-705ab6a7e753/1770e30ba80f971e23fd2a7bb77c3bb4.jpg”/>
The normal thickness of a PCB board is usually between 1.0 mm and 2.0 mm. Ultra-thin PCBs refer to printed circuit boards that are thinner than regular PCBs. Typically, PCBs smaller than or equal to 0.6mm are considered thin PCBs, while those with a thickness of 0.1mm-0.4mm can be classified as ultra-thin PCBs.
At times, due to space or margin limitations, or for design purposes, thinner thicknesses (such as 0.25mm, 0.20mm, or even 0.1mm) are required to make PCBs suitable for SIM and sensor cards. Thus, very thin or ultra-thin PCBs have emerged. With the increasing demand for thinner devices in the market, there is a growing trend towards making designs more portable, lightweight, and flexible, leading to a widespread application of ultra-thin PCBs.
For FR-4 ultra-thin PCBs, we can produce them at 0.15 mm, 0.20 mm, 0.25 mm, and 0.3 mm, with or without solder mask, and with copper thicknesses of 1/2 oz, 1 oz, 2 oz, and 3 oz.
Thin PCBs with various thicknesses, ranging from 0.075mm to 0.6mm, are available in different materials such as flexible core materials, FR4 core materials, BT core materials, and other PCB materials.
Ultra-thin FR4 PCBs can be as thin as flexible PCBs and can be bent like flexible circuits, but they are stronger and more cost-effective. Of course, flexible materials and BT materials can also be used to produce very thin PCBs. If the thickness of the circuit board required is less than 0.1mm, flexible circuits should be used. For 1L FPC, its thickness can be 0.6 millimeters, while for 2L FPC, the thickness can be 0.10 millimeters.
When choosing a very thin PCB thickness, the selection of available surface treatments may be limited. Each surface treatment has different manufacturing processes based on material characteristics and production methods. Our standard gold-plated surface treatment does support PCBs with a minimum thickness of 0.1 millimeters.
The production of ultra-thin PCBs requires specialized equipment, such as specialized cutting machines, production sheet racks, horizontal conveyors, etc., all of which require specialized fixtures.
FR-4 ultra-thin PCBs are made from thermosetting or thermoplastic plastics and are widely utilized in electronics, automobiles, and aerospace, replacing metals and glass in many industrial applications. They can also perform well under harsh conditions such as high temperatures.
The most common types of FR-4 ultra-thin PCBs in the current market are as follows:
Pure Polyamide
Third-generation ultra-thin
Ultra-thin filling
Low-flow polyimide
Traditional PCB boards usually have a thickness of 2mm or 3mm, but using FR-4 ultra-thin PCBs can reduce processing costs, improve quality, and significantly reduce production costs.
