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 …
Single-sided Printed Circuit Board Manufacturing Process Single-sided copper clad laminate –> blanking –> (brushing, drying) –> drilling or punching –> screen printing circuit anti-etching graphics or use dry film –> curing inspection repair board –> etching copper –> Resist printing material removal, drying –> Brushing, drying –> Screen printing impedance pattern (commonly used green oil), …
What is the Thermoelectric Separation Substrate? The circuit part and the thermal layer part of the substrate are on different circuit layers, and the thermal layer part directly contacts the heat dissipation part of the lamp bead to achieve the best heat dissipation (zero thermal resistance) effect. And the material of the substrate is generally …

There are a lot of parameters to be confirmed when making PCB. It’s easy to understand the parameters such as size, quantity, plate materials, thickness, solder resist color and silk screen color. But there is some parameters that are not so easy to understand, such as copper thickness, minimum line width / line distance, minimum aperture, through-hole …
The company uses dry film in the PCB production process, combined with various problems and solutions in production. This article introduces the characteristics and application technology of dry film for your reference. Composition of Dry Film Dry film consists of the following parts Polyester cover film: It is a carrier of photosensitive emulsion with a thickness of 1mil, …

PCB circuit board exposure includes circuit exposure and solder resist exposure. The function is to solidify the irradiated local area through ultraviolet irradiation, and then develop it to form circuit pattern or solder resist pattern. The process of line exposure is to paste the photosensitive film on the copper clad laminate first, and then expose …
Refer to PCB manufacturing process, after the PCB has been PTH(plated through hole) & PP(Panel Plating), it is time to do Membrane Pasting. A layer of blue dry film is pressed on the laminated circuit board. The dry film is a carrier and is very important in the circuit process. The dry film process is …
There are many types of metal-based printed boards. Aluminum PCB is one of most used metal PCB. Today we will introduce the produce process of single-sided aluminum PCB. Single-sided Aluminum PCB Produce Process Cutting Generally, a base material with a protective film on the aluminum surface is used. After cutting, the board does not need to be …
Before leaving the manufacturer, the bare PCB (printed circuit board) and PCB assembly (PCBA) must pass the electrical test to ensure that the circuit board has high performance and high reliability in the final product. Conduct electrical tests to find electrical and circuit problems, such as short circuits, open circuits, resistance, capacitance, etc. All these …
