The company uses dry film in the production process, combined with various problems and solutions in the production. Now on the dry film characteristics and application process for an introduction. For your reference in the work. The Composition of Dry Film Dry film also known as dry film photoresist. Dry film, composed of the following…
PCB prototyping is a key part of the hardware product development process, directly affecting the efficiency and quality of product development. Especially for electronic engineers, PCB prototyping is not only an important means of confirming the design drawings, or plan to produce large quantities of PCB boards the initial steps. In this article, we will analyze…
Ordinary PCB is usually made of copper foil and substrate, and the substrate material is mostly fiberglass (FR-4), phenolic resin (FR-3), and other materials. The adhesive is usually phenolic, epoxy, etc. During the PCB processing process, due to thermal stress, chemical factors, improper production processes, etc., or due to the asymmetry of copper paving on…
The currently available PCB cleaning processes include water-based cleaning, semi-aqueous cleaning, solvent cleaning, and no-clean process. We have discussed the first 3, today we will introduce no-clean process. What is a No-clean Process? The no-clean process refers to the quality and process control of raw materials such as printed circuit boards and electronic components. The alternative…
Soldering is an important step in the production of electronic equipment. After soldering, there are always varying degrees of flux residues and other types of contaminants on the circuit board surface, even if a low-solid content, halogen-free, no-clean flux is used. There will still be more or less residue. In order to prevent circuit failure…

The standard thickness of a printed circuit board (PCB) can vary based on the specific application, type of PCB, and the industry standards followed. However, some common standard thicknesses exist. Here are a few examples: Standard Thickness for Single-Sided PCBs: 1.6 mm (0.063 inches) is a commonly used standard thickness for single-sided PCBs. Standard Thickness…
Printed circuit board (PCB) manufacturing involves several steps to create a functional PCB that can be used in electronic devices. Below is an overview of the typical PCB manufacturing process: Design and Layout The process begins with the design of the PCB. Engineers and designers use PCB design software to create a schematic diagram and…
Flexible Circuit boards are generally customized products with widely varying shapes and performances. They can be divided into the following types according to the number of layers. 1. Single-sided Flexible Board Lowest cost. When the electrical performance requirements are not high and single-sided wiring is possible, a single-sided flexible board should be selected. This most…
