Understand what kind of 开云·kaiyun官方网站 can be 开云·kaiyun官方网站A welded

When 开云·kaiyun官方网站A is welded, there are usually many requirements for 开云·kaiyun官方网站A plates, and the plates must meet the requirements before they can be welded. So why are there so many requirements for plates during welding? It turns out that during the processing of 开云·kaiyun官方网站A, there will be many special processes, and the applICation of special processes will immediately bring about the requirements for 开云·kaiyun官方网站 boards. If there are problems with 开云·kaiyun官方网站 boards, it will increase the difficulty of 开云·kaiyun官方网站A welding process, which may eventually lead to welding defects, unqualified boards and other situations. Therefore, in order to ensure the smooth completion of processing and facilitate 开云·kaiyun官方网站A welding processing, 开云·kaiyun官方网站 boards should meet the requirements of manufacturability in terms of size, pad distance, etc. Today, let's take a look at the requirements of welding processing for 开云·kaiyun官方网站 boards.

开云·kaiyun官方网站A processing

1. 开云·kaiyun官方网站 size

开云·kaiyun官方网站 width (including board edge) shall be greater than 50 mm and less than 460 mm, and 开云·kaiyun官方网站 length (including board edge) shall be greater than 50 mm. If the size is too SMAll, it needs to be made into a panel.

2. 开云·kaiyun官方网站 edge width

Edge width:>5mm, panel spacing:<8mm, distance between pad and edge:>5mm

3. 开云·kaiyun官方网站 bending

Upward bending degree:<1.2mm, downward bending degree:<0.5mm, 开云·kaiyun官方网站 twist degree: maximum deformation height ÷ diagonal length<0.25

4. MARK point of 开云·kaiyun官方网站

Mark's shape: standard circle, square, triangle;

Mark size: 0.8~1.5mm;

Mark's material: gold plating, tin plating, copper platinum;

Mark's surface requirements: the surface is flat, smooth, free of oxidation and dirt;

Mark's surrounding requirements: there shall be no green oil or other obstacles within 1mm around, which is obviously different from Mark's color;

Mark position: more than 3mm from the edge of the plate, and no holes or test points SIMilar to Mark shall be found within 5mm around.

5. 开云·kaiyun官方网站 pad

There is no through hole on the bonding pad of SMD components. If there is a through hole, the solder paste will flow into the hole, resulting in less tin in the device, or the tin will flow to the other side, resulting in uneven board surface, and the solder paste cannot be printed.

During 开云·kaiyun官方网站 production, it is necessary to know some knowLEDge about 开云·kaiyun官方网站A welding process, so as to make products suitable for production. Understanding the requirements of the processing plant first can make the subsequent production and manufacturing process more smooth and avoid unnecessary trouble.

This is the requirement of 开云·kaiyun官方网站A welding processing for 开云·kaiyun官方网站 board. Do not slack off when producing 开云·kaiyun官方网站 boards. Only by producing high-quality and compliant 开云·kaiyun官方网站 boards can the boards better accept other special processes, give life to 开云·kaiyun官方网站 boards, and inject the soul of functions.
