What are the common demands of solder paste manufacturers in JJY?

Each oneSolder paste manufacturerEveryone wants to acquire more customers and sell more solder paste. To achieve this, we must have a thorough understanding of the demands of relevant purchasers for the products. Next, Shenzhen JJY Solder Paste Manufacturer will talk about what the more common demands are:

１Poor conditions such as Wuxi beads, continuous soldering or false soldering, and missed soldering. These conditions are relatively typical defects in electronic soldering, and generally, manufacturers will conduct relatively strict inspections and controls on them. To ensure good quality in production, it is important to choose the correct solder paste. Choosing solder paste with appropriate activity and good wettability, along with a good process as a complement, is the fundamental factor to avoid these adverse effects.

2There is no residue or whitening on the board surface. In the face of such requirements from customers, most manufacturers will choose no-clean flux paste. If the post-weld whitening is indeed caused by the material issue, the post-weld cleaning method can be adopted to solve the problem.

３The solder joints are fully tinned. This is90%For the requirements raised by the above-mentioned guests, to ensure that the solder joints are fully tinned, it is necessary to select solder paste with appropriate activity and good wettability.

4It has no leakage or other poor electrical performance. If the customer has such requirements, try not to choose solder paste with strong activity or high halogen content. If the condition of the board is not good, such flux must be used. We can solve the problem by cleaning.

5The solder joints are bright.63/37Under normal circumstances, the solder joints of alloys are relatively bright. If the tin content is low or the impurities exceed the standard, the solder joints will not be as bright relatively. Ordinary solder paste does not cause a matting effect on the solder joints, except for matting type solder paste. The solder joints of rosin-type flux paste are relatively brighter than those of rosin-free flux paste. If components that make the solder joints brighter are added to the flux paste, the solder joints will be even brighter after soldering.

Do you all know now? To acquire more customers, the first thing is that the quality of the solder paste must be qualified. As a 16-year-old veteran solder paste manufacturer, JJY has been dedicated to the research and development and production of solder paste for many years. The quality of the solder paste is stable, without solder bonding, false soldering or establishing a reputation. No residue, Wuxi beads, bright and full solder joints; The weld points are firm and have excellent electrical conductivity.
