The principle and advantages of laser tin ball jet welding

The principle and advantages of laser tin ball jet welding

Nov 25, 2022

First of all, we need to understand the working principle of laser solder ball spray welding. The solder balls of the laser spray tin soldering welding system are transported from the solder ball box to the nozzle. After being heated and melted by the laser, they are sprayed out from the special nozzle and directly cover the pad without additional help. Flux, no other tools. Solder ball spray welding is adopted, and the welding precision is high, and there is a requirement for temperature or the soft board is connected to the welding area.

Solder paste inspection equipment is a measurement equipment in SMT chip processing that has been introduced in the past two years. Similar to AOI. Solder Paste Inspection (SPI) is to check the height, volume, area, short circuit and offset of solder paste after solder paste printing.
At present, the main inspection methods in the field of SPI are laser inspection and fringe light inspection. Wherein the laser method is realized with a point laser. Since the point laser and CCD image acquisition must have an X, Y point-by-point mechanism, the measurement speed has not been significantly increased. In order to increase the measurement speed, the point laser is changed to a scanning line laser light.

The solder bar is a bar-shaped tin solder, referred to as a tin bar for short. Solder bars are mainly used for wave soldering and dip soldering in SMT patch processing, and a small amount is used for flame brazing or electric soldering of large structural parts and long welds.

Solder paste laser welding technology uses semiconductor lasers as the light source, and the commonly used laser wavelengths are generally 915nm or 976nm. Different from the traditional solder paste soldering method, the former solder requires laser-specific solder paste. The principle is that the laser energy can be precisely controlled through the optical lens and focused on the corresponding solder joints, which belongs to the non-contact heating welding technology.

Solder balls are mostly used in the processing and production of circuit boards. However, due to the inhomogeneous fusion process of flux and metal in commonly used solder balls, it is easy to cause metal solution to splash, resulting in short circuit of the product, which has a bad influence on the stability of product quality.
The distinction between silver-containing tin wire and tin-copper tin wire

The distinction between silver-containing tin wire and tin-copper tin wire

Lead-free tin wire is generally divided into silver-containing tin wire and tin-copper tin wire. So how to distinguish these two tin wires? Let me introduce it to you.
1. Due to the role of silver metal, silver-containing solder wire has better, stronger firmness and stronger solder joints than tin-copper lead-free solder wire.

How to control the temperature of solder wire during use?

When we use solder wire for welding, we should effectively control the temperature, so as to ensure that the solder wire has a better welding effect.
1. When using solder wire, if there is still solder wire left in the tin furnace, do not cut off the heating power supply of the tin melting furnace. At this time, the temperature should be properly controlled, and the set temperature should not be too high , to avoid accelerating the oxidation reaction of the tin surface. Generally, we can control the temperature of 63/67 solder wire at about 250 degrees Celsius, the temperature of 50/50 solder wire should be controlled at about 280 degrees Celsius, and the temperature of 30/70 solder wire should be controlled at about 300 degrees Celsius.

The selection of solder paste in the LED industry can generally use lead-free LED solder paste and leaded LED solder paste. If lead-free solder paste is used, high, medium and low temperature solder paste is generally used. Lead-free solder paste If you want to solder cheaper or low-melting point components, use tin-bismuth low-temperature solder paste. If you want good soldering quality, use tin-bismuth-silver medium-temperature solder paste.
Which is better to use, lead-free solder wire or leaded solder wire?

Which is better to use, lead-free solder wire or leaded solder wire?

Lead-free solder wire and leaded solder wire are divided into two categories according to the environmental protection standards of solder wire. Recently, some customers have asked whether it is better to use lead-free solder wire or leaded solder wire? This problem is actually a matter of benevolence and wisdom, and it has a certain relationship according to different products and component materials.

Rosin solder wire, as its name implies, is solder wire containing rosin. The production of solder wire is roughly divided into two methods due to different production processes. One is solid solder wire, that is, solder wire without rosin, and the other is It is a solder wire injected with rosin core during the production process. Let us introduce the little knowledge about rosin solder wire in detail below:
