How to improve solder paste printing yield?

图片
 To improve solder paste printing yield, you can start from the following aspects: I. Quality control of solder paste Select high-quality solder paste: In addition to selecting solder paste from a reliable manufacturer, the shelf life and batch stability of the solder paste should be considered. Select specialised solder pastes for different application requirements (e.g. high temperature, high humidity, high frequency, etc.). Storage and use environment: Set up a special solder paste storage room to maintain a constant temperature and humidity environment. Follow the "first-in-first-out" principle to ensure the use of the latest production of solder paste. Stir the paste thoroughly before use to eliminate particle settling and agglomeration. Equipment and process optimisation Equipment calibration: Perform regular equipment maintenance, including cleaning, lubrication and adjustments. Use precision measuring tools to calibrate the printing machine to ensure that the accu...

Explain the principle and advantages of laser solder paste

图片
 Laser solder paste technology, as an advanced means of soldering, has shown significant advantages in the field of electronics manufacturing.Its principle and advantages are detailed below: I. Principle The principle of laser solder paste is based on the application of laser light as a highly efficient heat source, and the soldering is achieved in the following steps: Paste application: First, a specially formulated solder paste is applied precisely to the area of the solder joint to be soldered. Laser heating: Next, the solder paste is rapidly and precisely heated using a laser beam, causing the solder particles to melt in a very short time. Solder flow and solidification: The molten solder flows and fills the solder joint area under the action of the laser, and then quickly cools and solidifies to form a stable and reliable solder joint. In this process, the laser beam generates a localised high temperature on the solder paste coating, which enables non-contact he...

How the price of solder paste is calculated

图片
 The price of solder paste is indeed calculated in a variety of ways, based on a number of factors such as purchase volume, usage, recycling and special customisation needs.Below is a detailed summary of these calculations: I. Basic Price Factors Brand and model: There are differences in the price of different brands and models of solder paste, and well-known brands and high-end models usually cost more. Composition and environmental requirements: The composition of the solder paste (e.g. leaded or lead-free) and whether it meets environmental requirements (e.g. RoHS certification) will affect the price. Lead-free solder pastes are usually more expensive due to higher raw material costs and stricter environmental requirements. Packaging specifications: The packaging specification of the solder paste (e.g., jar, syringe, etc.) also affects the price. Small packages are usually used for retail, the price may be slightly higher; large packages for bulk purchases, the unit p...

What is wafer microbumping packaging?

图片
 Wafer microbumping packaging, more commonly expressed as Wafer Microbumping or Wafer Bumping, is an advanced semiconductor packaging technology.The following is a detailed explanation of Wafer Bumping: I. Definitions and rationale Wafer micro-bump packaging refers to the formation or installation of tiny bumps (also known as bumps) at pre-determined locations on the wafer before it is cut into individual chips, which will serve as interfaces between the chip and external circuitry.The principle involves creating a series of bumps on the surface of the wafer to interconnect the chip to a PCB (printed circuit board) or substrate. II. Methods of Bump Formation Wafer bumping technology includes a number of different bump formation methods, such as: Printed bumps: Bumps are formed on wafers by printing. Electroplated bumps: Bumps are formed by depositing metal on a wafer using electroplating technology. Other methods: e.g. eutectic plating type drop balls, lead-free alloys and...
