Have you noticed that now more and more of our lighting is using led lighting.What is LED? Compared to the traditional light bulbs, LEDs have lower power consumption, longer lifetime and higher energy efficiency. In the PCB industry,when we say LED PCB, it refers to the pcb used for LED lighting, if you are looking for a suitable LED PCB for your lighting system, this article may bring you something. WHAT ARE LEDS COMPOSED OF?LED is an initial light-emitting diode that produces light when an electric current passes through. LEDs typically have negative and positive electrodes, which generate light in the visible light region.The LEDS are glued to the PCB by soldering process and have electrical connections for lighting.Since light-emitting diodes dissipate a lot of heat when they are in use, when you are designing LED, the metal core is usually the best choice for LED PCB, it is because that it dissipates heat more faster. Among them, the metal material aluminum is the most widely used
Copper circuit boards mainly consist of the following parts: 1. Substrate: usually fiberglass cloth impregnated with epoxy resin or other synthetic resins to form a hard composite material. 2. Copper foil: A thin layer of copper covering the surface of the substrate, typically ranging in thickness from a few micrometers to tens of micrometers. 3. Circuit pattern: A conductive path formed on copper foil through processes such as etching and electroplating, used to connect various electronic components. The process of manufacturing copper circuit boards mainly includes the following steps: 1. Design and plate making: Use computer-aided design (CAD) software to design circuit patterns and create photo plates. 2. Lamination: The copper foil and substrate are bonded together by hot pressing. 3. Exposure and development: Use photosensitive resin and photoresist to expose and develop, forming a mask for circuit patterns. 4. Etching: By chemical etching or laser cutting, unwanted c

Printed Circuit Board (PCB) is one of the essential core components in modern electronic devices. It achieves electrical connections and signal transmission between electronic components by etching fine copper wires on insulating substrates. Copper printed boards are widely used in various fields such as computers, communication equipment, consumer electronics, and medical instruments, playing a crucial role. Firstly, copper printed boards have excellent conductivity and stable chemical properties. The low resistance and high thermal conductivity of copper make it an ideal material for making circuit boards. By coating a thin layer of copper foil on the substrate, followed by a series of processes such as exposure, development, and etching, complex circuit patterns are formed to ensure the efficient operation and heat dissipation requirements of electronic devices. Secondly, copperplate printing has a high degree of integration and flexibility. Modern electronic products pursue m
1、 The materials used for PCB circuit boards are different Taking ordinary double-sided boards as an example, the board materials generally include FR-4, CEM-3, etc. The board thickness ranges from 0.6mm to 3.0mm, and the copper thickness ranges from? Oz to 3 Oz are different. In terms of solder mask ink, there is also a certain price difference between ordinary thermosetting oil and photosensitive green oil. 2、 Different production processes are used for PCBs Different production processes will result in different costs. Products such as gold-plated plates and spray tin plates, as well as gongs (milled) and beer (punched) plates used for shape production, and the use of silk screen and dry film circuits will result in different costs. 3、 The difficulty of PCB circuit boards themselves varies Even if the materials are the same and the processes are the same, the difficulty of the PCB itself will result in different costs. If there are 1000 holes on both types of circuit boards
