Mini led, also known as millimeter led, refers to the LED with grain size of about 50-200 μ m, and its grain size and point spacing are between the traditional small spacing led and micro led. As the outpost of micro led, mini led was put forward after micro led. Due to the key technical bottlenecks such as miniaturization process, massive transfer and full-color and high cost problems in micro led, it is necessary to develop Mini led with larger grain size, traditional process technology and lower technical difficulty. Combined with flip chip cob or IMD

In order to maintain the best performance of the steel mesh, it is necessary to clean the steel mesh from time to time in the process of using. Generally, 3-5 pieces of steel mesh are printed online, and the steel mesh must be wiped and cleaned. With the improvement of the precision of electronic products and the reduction of the distance between devices and lines, some even need to clean the steel mesh every time it is printed. What kind of solvent and equipment is very important, we collect some cleaning solvent and equipment information, hope to help you. What solvent is used for cleaning SMT steel mesh? 1. The water-based solvent needs to change the filter element and cleaning agent regularly, which is safer, fireproof and explosion-proof. 2. High concentration alcohol, purity at least 95%, easy to do fire and explosion-proof measures, pay attention to ventilation 3, IPA solvent

SMT steel mesh manufacturer is specialized in providing steel mesh for SMT SMT SMT industry. The main purpose of SMT steel mesh is to make solder paste printed on circuit board, and then paste components through SMT machine. After reflow soldering, SMT chip processing is completed. Steel mesh is the first process in SMT industry, so the steel mesh produced by steel mesh manufacturer has a direct impact on the quality of SMT chip processing plant Today, let's learn about the production process of SMT steel mesh manufacturer, and compare laser SMT steel mesh with other ordinary SMT steel mesh. SMT steel mesh manufacturer production process: SMT steel mesh manufacturers generally have two processes: etching SMT steel mesh process, laser SMT steel mesh process; because of the ring

BGA: ball grid array package. Compared with TSOP, BGA has smaller volume, better heat dissipation and electrical performance; its storage capacity per square inch has been greatly improved, and its volume is only one third of that of TSOP package under the same capacity. In order to improve the efficiency of GBA placement, we summarize some BGA welding defects and solutions in SMT surface mounting process, and share them with you. The following figure shows the normal BGA welding process and effect, which can be compared with the defects described below. BGA welding process and effect in SMT processing

SMT steel mesh is the necessary consumables in SMT chip production, and its quality directly affects the pass through rate of SMT. How to produce high-quality SMT steel mesh is the direction that every SMT steel mesh enterprise will always explore. Today, there are many SMT equipment used for the first time in Linchuan precision, and the working environment requirements of SMT production equipment are not very well understood. Based on this, Shenzhen Zhichi technology has collected some environmental requirements for your reference: 1. Requirements for bearing capacity, vibration and noise of the workshop: 1 SMT production equipment is a high-precision mechatronics equipment. The equipment and process materials have certain requirements for environmental cleanliness, humidity and temperature. The bearing capacity of plant floor should be greater than 8kN / m2, and the vibration should be controlled within 70dB;

The printing templates used in the printing press of SMT mountings are collectively referred to as SMT steel mesh. Due to the different use field, manufacturing process and name, we will classify the SMT steel mesh for you now. SMT steel mesh is classified by printing materials: 1. Solder paste steel mesh: as we all know, it is used to brush solder paste on the steel plate with holes corresponding to the printed circuit board pad The solder paste is then transferred to the printed circuit board through the steel mesh. When printing solder paste, put the circuit board under the SMT steel mesh, apply the solder paste on the steel mesh, and then scrape the solder paste evenly on the steel mesh with a scraper (the solder paste will flow down from the steel mesh and cover the circuit board during extrusion) to paste the chip components, evenly reflow and solder the plug-in components manually.

SMT steel mesh is a kind of mold specially used for printed circuit board. SMT steel mesh mounting technology refers to the surface assembly technology of circuit assembly, that is, surface assembly components without pins or short leads are installed on the surface of printed circuit board or other substrates, and are welded and assembled by reflow soldering or immersion welding. Uneven solder paste is often found in the production. The following is to share with you the specific reasons for this problem and solutions. SMT stencil printing paste effect what are the causes of insufficient and uneven solder paste in SMT stencil: 1. The fixing clip of circuit board in SMT stencil printing machine is loose. 2. Solder spatula or SMT steel mesh is damaged. 3. SMT stencil printing machine can not make up solder paste in time

SMT steel mesh is an essential consumable in the production process of our SMT assembly enterprises. Generally, we need to make one when there are new models. Although the price of SMT steel mesh accounts for a small proportion in the cost of a batch of products, many customers will ask you how much a piece of SMT steel mesh is, and what factors determine the price of SMT steel mesh. Today, Lin Chuan analyzes the answers for you. How much is SMT steel mesh? The price of SMT steel mesh is generally between 100 yuan and 400 yuan per piece, some special steel mesh will be more expensive, such as ladder steel mesh generally more than 400 yuan, nano steel mesh more than 1000 yuan and so on.

Seeing this title, a friend may ask: "it's all made by laser machine. What's the difference in accuracy?". It's true that the precision of SMT steel mesh produced by laser machine is relatively high, and the allowable tolerance in the line is within 0.01mm. However, if the SMT steel mesh manufacturer lacks technology and is not strictly controlled, the tolerance range can not be controlled. Next, we introduce the precision function of SMT steel mesh and the control method of precision of SMT steel mesh.

Mini LED is a micron sized LED chip, each chip can be controlled and lit independently. Each mini LED circuit board usually has thousands of chips and tens of thousands of solder joints to connect RGB Tri Color chips. At present, such a large amount of solder joints can only be solved by printing, and the most important SMT steel mesh (template or mask) in printing is very important. Its technology and maturity directly affect the through rate of mini led. The following is to introduce the SMT steel mesh Mini led nano steel mesh produced by Linchuan precision specialty for mini LED packaging
