The traditional manual cleaning process for screen printing screens involves dipping cloth strips into cleaning solution or anti-white water for scrubbing, typically cleaning one side before proceeding to the other. However, this process poses several challenges and issues: Many companies have been aware of these issues for many years, especially those that prioritize quality and…

In simple terms, the effects of the stencil on SMT printing defects mainly come from seven aspects: stencil thickness, number of apertures (either too many or too few), aperture position, aperture size, aperture shape, roughness of the aperture walls, and cleanliness of the apertures after stencil use. Let’s elaborate on each of these: To control…

The pick-and-place machine nozzles play a significant role in the placement rate (SMT placement rate) in PCB manufacturing companies. Many people value the SMT placement rate because it not only affects the production cost of the production line but also influences the operational efficiency of the production workshop. Let’s briefly introduce how nozzles affect the…

The nozzle cleaning machine, also known as the pick-and-place machine nozzle cleaning machine or SMT nozzle cleaning machine, is a device used for cleaning pick-and-place machine nozzles. This type of machine is commonly referred to as a nozzle cleaning machine, and in some places, it is also called a nozzle cleaner. Principle of Nozzle Cleaning…

Stencil cleaning machines are divided into two main categories: pneumatic stencil cleaning machines and electric stencil cleaning machines. Many newcomers to the SMT industry may wonder what stencil cleaning machines are used for. In fact, stencil cleaning machines are industrial cleaning equipment used to clean stencils. Specifically, they are used to remove residues such as…

When discussing the importance of the PCBA cleaning process, it involves various aspects such as cleaning methods, cleaning agents, and cleaning standards. User Zhang Min mentioned several instances where improper cleaning led to changes in device performance, such as reduced insulation performance of transformers and decreased contact performance of key switches. Recently, Zhang Min specifically…

PCB cleaning machines with surface dust and electrostatic discharge (ESD) removal systems have become increasingly popular. Many newcomers may wonder, “Isn’t a PCB board ready for use straight away?” However, during various stages such as handling, barcoding, and placement of PCBs, dust and stains may accumulate on the surface layer, and static electricity on the…

The pneumatic stencil cleaning machine offers clear advantages compared to ultrasonic stencil cleaning machines and manual cleaning methods for stencils. Regardless of whether it’s ultrasonic or manual cleaning, the ultimate challenge lies in how to clean stencils with small apertures and effectively avoid damaging the stencil. Below, we’ll primarily discuss what a pneumatic stencil cleaning…
