Is spray solder paste, spray printing solder paste the same?

Injected solder paste and printed solder paste essentially refer to the same technology or process whereby solder paste is precisely coated or deposited onto a specified substrate using a jetting process.The spray printing process utilises high-speed jetting valves to precisely deposit tiny droplets of solder paste onto PCB pads with high accuracy, speed and flexibility.Compared with traditional stencil printing and syringe dispensing processes, the spray printing process saves solder paste, reduces costs and avoids problems such as uneven printing.Printed solder paste needs to have good sphericity, particle size distribution, thixotropy and rheology, as well as moderate viscosity and wettability.Below is a detailed explanation of both:

Spray solder paste

Solder Paste Spraying is a technology that sprays solder paste quickly and accurately into a specified location by means of a high-pressure gas or other power source.This technology is commonly used in electronics manufacturing, semiconductor packaging, and other fields, especially in dispensing operations that require high precision and efficiency.Jet paste technology can significantly reduce the need for just-in-time corrections in mass production runs, reduce difficulties in small-lot production processes, and effectively shorten lead times.

Spray Printing solder paste

Solder Paste Spraying, also known as Solder Paste Printing Technology, is a non-contact, precision dispensing technology.It utilises an injector to spray solder paste at very high speeds above the substrate, similar to the working principle of an inkjet printer.The solder paste spraying technology has the advantages of fast spraying speed, high dispensing precision, no contact and no pressure in the spraying process, high controllability and high material utilisation.This technology breaks through the limitations of traditional solder paste printing technology and provides an excellent solution for hybrid assembly processes, flexible circuit board assembly, and 3D solder paste deposition.

relationship between the two

Jet solder pastes and printed solder pastes are similar in terms of process principles, application areas, and technical features.They both use jetting to precisely apply solder paste to a specified location, and both are widely used in fields such as electronics manufacturing and semiconductor packaging.Therefore, it can be considered that sprayed solder paste and printed solder paste are different expressions of the same technology or process.

Overall, Jet Paste and Printed Paste are the same and both refer to the process of precisely applying solder paste to a specified substrate using jetting technology.
