A repeat customer specializing in high-technology interconnect, sensor, and antenna solutions, partnered with us to dispense small volumes of solder paste (Indium 10.1 SAC305 T6SG 78%m) onto backplane connectors – gold pads 0.175mm x 0.225mm. We performed a test requiring 0.200mm diameter or smaller dots to demonstrate the dispensing capability required.

Mastering Precision: I.C.T's SMT Conformal Coating Valves Introduction Of SMT Conformal Coating Valves: In various industries, including electronics, lighting, energy, and life sciences, the SMT conformal coating process plays a critical role. Precision is key, and the choice of a SMT coating valve significantly influences application quality. This article explores I.C.T's SMT conformal coating valves, focusing on the C-0101, C-L101, PJ-01, PJ-01 (with plastic bucket), C-0100, D-0100, D-0300, and the W Series. C-0101 Water Curtain Spray SMT Conformal Coating Valves: The C-0101, a non-atomizing water curtain spray valve, excels with low-viscosity solvent materials. It ensures clean and precise edges in applications like conformal coatings, UV adhesives, backfilling, and volatile substances. C-L101 Rotary Water Curtain Spray Valve: Similar to the C-0101, the C-L101 suits low-viscosity solvent materials, offering a precise edge without splashing for various coatings. PJ-01 Injection Valve (Without Plastic Bucket): Designed for high-precision applications in electronics, lighting, energy, and life sciences, the PJ-01 excels in accurate dispensing and coating. It accommodates various materials, including red glue, liquids, and pastes. PJ-01 Injection Valve (With Plastic Bucket 30CC): The PJ-01, with a 30cc plastic bucket, maintains high precision for complex circuit board applications, offering precise dispensing for materials like red glue, liquids, and pastes. C-0100 Non-Rotating Film Valve: Different from pneumatic atomizing valves, the C-0100 provides precise edge definition without air pressure involvement. It addresses issues related to atomizing drift and fast-drying adhesives, allowing control over the film width. D-0100 Precision Valve: The D-0100, with a unique fluid-sealing structure driven by compressed air, minimizes seal replacement frequency. Suitable for various fluid dispensing, it handles UV adhesives, encapsulating materials, silicones, epoxies, and surface coatings. D-0300 Dispensing Valve: Tailored for precision fluid dispensing at low driving pressure, the D-0300 accommodates a range of materials, including acrylics, silicones, epoxies, and UV adhesives. It's ideal for applications where accuracy and consistency are crucial. W Series: Needle Design Atomization Valves: The W Series offers needle design valves leaving zero residue. Easy to clean without disassembly, they provide adjustable fluid and air pressure for various coating materials, ensuring excellent atomization effects. Analyzing The Options: When selecting a conformal coating valve, consider specific application requirements. C-0101 and C-L101 suit low-viscosity solvent materials, providing clean and precise edges. PJ-01, with or without a plastic bucket, offers high-precision dispensing for complex applications. C-0100 and D-0100 are versatile for various materials, and D-0300 excels in precision dispensing. The W Series offers residue-free needle design atomization valves. Choose based on material, precision, and coating needs. Integration with I.C.T's Conformal Coating Machines: Integral to I.C.T's Conformal Coating machines, these valves enable precise application tailored to specific requirements. Machines like I.C.T-T550, I.C.T-T550U, I.C.T-T600, and I.C.T-T650 come equipped with a range of valve options catering to diverse production line needs.

Principle of shielding 1 The principle of shielding is creating a conductive layer completely surrounding the object you want to shield. This was invented by Michael Faraday and this system is known as a Faraday Cage. 2 Ideally, the shielding layer will be made up of conductive sheets or layers of metal that are connected by means of welding or soldering, without any interruptions. The shielding is perfect when there is no difference in conductivity between the used materials. When dealing with frequencies below 30 MHz, the metal thickness affects shielding effectiveness. We also offer a range of shielding methods for plastic enclosures. A complete absence of interruptions is not a realistic goal since the Faraday cage will have to be opened from time to time so electronics, equipment or people can be moved in or out. Openings are also needed for displays, ventilation, cooling, power supply, signals etc. 3 Shielding works in both directions, items inside the shielded room are shielded from outside influences.
