Among the numerous dispensing equipment, solder paste dispensing differs from other fluid adhesives, so the dispensing valve equipment used is also required to be different, targeting Solder Paste Dispensing Valve For difficult selection situations, Leica has launched a solder paste dispensing valve, suitable for solder paste dispensing while also suitable for many other types of fluid dispensing, which is a very good choice.
Mr. Liu has a company that produces circuit boards. Due to production needs, he needs to find a suitable Solder Paste Dispensing Valve equipment. Mr. Liu met Leica at the Shenzhen Science and Technology Expo, and since then began a cooperative relationship with Leica. Mr. Liu saw Leica's solder paste dispensing valve at the exhibition and immediately became interested. After some understanding, Mr. Liu came to Leica for initial testing. The test results were very satisfactory, and a cooperation was immediately reached, ordering more than a dozen pieces of equipment. Mr. Liu is also a very straightforward person, praising Leica's dispensing valve equipment, saying that if it is easy to use, he will cooperate again. Leica will not let you down.
Leica Solder Paste Dispensing Valve Attracting customers with quality, committed to making every customer satisfied, Leica's good quality and good technology will surely bring customers a better experience.

How can daily maintenance help extend the service life of a valve body?
As a precision component that operates at high frequency, the precision dispensing valve requires scientific daily maintenance to extend its service life and maintain dispensing accuracy. Shenzhen Laike Technology has compiled the following key maintenance points for you: Daily cleaning is crucial and should not be overlooked. After finishing work, promptly remove any residual adhesive from the exterior of the valve body, especially around the nozzle and plunger area. Once cured, adhesive can cause blockages or wear, affecting subsequent use. It is recommended to gently wipe with a suitable cleaning solvent, taking care not to damage the seals. Regularly inspect sealing components—seals and other parts will naturally degrade over time during prolonged operation. We recommend checking their condition periodically based on usage frequency. If you notice signs of hardening or wear, replace these components promptly to prevent adhesive from seeping into the valve body and causing more serious damage.
The stringing issue during the dispensing process is often closely related to fluid properties, equipment parameters, and process settings. Drawing on years of industry experience, SZLKTE has compiled and optimized key points for you: Fluid temperature control is crucial. Proper heating can reduce the viscosity of the adhesive, improve its flowability, and minimize stringing and trailing. SZLKTE’s dispensing valves can be equipped with precision temperature-control modules to ensure that the fluid remains in a consistently stable working state. The back-suction parameters must be finely adjusted. The negative-pressure back-suction applied at the moment the glue dispensing stops can effectively cut off the adhesive flow, preventing dripping and stringing. We recommend gradually adjusting the amount and speed of back-suction according to the adhesive’s viscosity until you find the ideal balance.
SZLKTE takes a multi-dimensional approach to ensure zero errors and long service life for its products even under high-speed, continuous operation. The piezoelectric valve series employs piezoceramic actuation technology; its non-contact drive design eliminates mechanical wear common in traditional solenoid valves, enabling a service life of over one billion cycles. At the same time, these valves deliver millisecond-level response times, completely eliminating trailing and stringing issues. The needle valve KC-9870, on the other hand, features a specially engineered, wear-resistant material for its needle component, offering exceptional resistance to abrasion and corrosion. Even in industrial environments with prolonged operation, this valve maintains outstanding stability. Moreover, its components can be quickly disassembled and maintained, significantly reducing production downtime.
Contact Dispensing vs. Non-Contact Jetting Valves: How Should You Choose for Micron-Level Processes?
Contact dispensing involves the needle making physical contact with the substrate surface to apply the fluid. Its main advantage lies in its strong adaptability to high-viscosity fluids and relatively controllable dispensing process. However, since it requires coordinated movement along the Z-axis, the dispensing speed is limited. Additionally, there is a risk of the needle colliding with and damaging the workpiece or deforming the needle itself. Therefore, careful evaluation is necessary when applying this method in miniaturized packaging scenarios. In contrast, non-contact jetting valves use a driving mechanism to rapidly spray adhesive onto the workpiece surface without any physical contact between the needle and the substrate. This feature makes them ideally suited for substrates with uneven surfaces or those that are fragile. They excel in micron-scale processes such as bottom-fill applications for chips and precision coating. The jetting method eliminates the need for Z-axis movement, significantly boosting production efficiency while also avoiding common issues associated with contact dispensing, such as stringing and trailing.
The stability of the piezoelectric valve dispensing process directly determines product quality. Common issues such as uneven dispensing, stringing, and glue leakage can be effectively addressed through parameter adjustments and optimized matching. Laike’s piezoelectric valves support multi-level parameter adjustments, enabling precise matching of pressure, injection frequency, and nozzle aperture according to the specific characteristics of different fluids.
Blocking the hole is Piezoelectric valve The most common failures in dispensing operations are often caused by fluid solidification, residual impurities, and nozzle wear, which directly affect dispensing accuracy and efficiency. Given the structural characteristics of piezoelectric valves, these issues can be addressed in three steps: “diagnosis—cleaning—inspection.” First, stop the machine and visually inspect the nozzle for obvious glue deposits or foreign objects, determining whether the blockage is temporary or a persistent issue caused by nozzle wear.
