No SMT equipment can place accurately and run efficiently without quality nozzles and feeders. These two factors are the core of the pick and place process. If the machine is either unable to pick parts consistently or hold on to the components during the transport from feeder to PCB, defects will result.

How to Choose the Right PCB Coating Machine Line Selecting the ideal equipment for your PCB coating line can be a complex task. In this article, we will guide you through the critical components of a standard PCB coating machine line and their solutions to common challenges. We'll delve into the line's composition, including the elevator, transfer station, coating machine, inspection station, curing oven, and their interconnectedness through a return conveyor. Let's explore each element and understand its role. Components of a PCB Coating Machine Line: Elevator: The PCB coating process starts with an elevator, efficiently transporting PCB boards to the next stage. Transfer Station: After the elevator, boards are conveyed to a transfer station, preparing them for the coating process. Coating Machine: The heart of the PCB coating line is the coating machine. We offer a range of coating machines, including I.C.T-T550, I.C.T-T550U, I.C.T-T600, and I.C.T-T650. Inspection Conveyor: Following the coating process, the boards move to an inspection station. The second transfer station is equipped with LED lights and a blue glass cover, enabling operators to closely inspect the coating quality. This feature is vital for ensuring consistent, dust-free coatings. Curing Oven: For UV-curable adhesives, we provide a UV curing oven to effectively solidify the adhesive. Return Conveyor: Beneath the entire line runs a return conveyor, connected to the elevator. This conveyor system efficiently returns PCBs from the last elevator to the first one, reducing manual handling and streamlining operations. The Advantages of the PCB Coating Line Design: 1. Easy Accessibility: The operator's station is strategically located beside the coating machine, ensuring easy access for setup and adjustments. 2. Enhanced Efficiency: The integrated return conveyor eliminates the need for manual transport, optimizing workflow. 3. Quality Control: The inspection station with the blue glass cover enables operators to inspect coatings for quality and cleanliness. 4. Dust Prevention: The blue glass cover also serves as a barrier to prevent dust contamination on freshly coated PCBs. Selecting the right PCB coating machine line is essential for achieving quality and efficiency in your operations. Our meticulously designed equipment line, along with its well-engineered components, can help you attain superior results. If you have further questions or need assistance in choosing the best solution for your specific requirements, please do not hesitate to contact us. We are committed to providing solutions that meet your needs and exceed your expectations.

Legislation against the use of lead in electronics has been the driving force behind the use of lead-free solders, surface finishes, and component lead finishes. The major concern in using lead-free solders in the assembly and rework Chip Scale Packages (CSPs) is the relatively high temperatures that the components and the boards experience. Fine-pitch CSPs have very low standoff heights following assembly making inspection and rework of these components more difficult. One other concern pertinent to rework is the temperature of the neighboring components during rework. These issues, coupled with the limitations of rework equipment to handle lead-free reflow temperatures, make the task of reworking lead-free assemblies more challenging.

Although reflow ovens may not have been dramatically changed during the last decade the reflow process changes step by step. With the introduction of lead-free soldering not only operation temperatures increased, but also the chemistry of the solder paste was modified to meet the higher thermal requirements. Miniaturization is a second factor that impacts the reflow process. The density on the assembly is increasing where solder paste deposit volumes decreases due to smaller pad and component dimensions. Pick and place machines can handle more components and to meet this high through put some SMD lines are equipped with dual lane conveyors, doubling solder paste consumption. With the introduction of pin in paste to solder through hole components contamination of the oven increased due to dripping of the paste.

The drive to reduced size and increased functionality is a constant in the world of electronic devices. In order to achieve these goals, the industry has responded with ever-smaller devices and the equipment capable of handling these devices. The evolution of BGA packages and leadless devices is pushing existing technologies to the limit of current assembly techniques and materials.As smaller components make their way into the mainstream PCB assembly market, PCB assemblers are reaching the limits of Type 3 solder paste, which is currently in use by most manufacturers.The goal of this study is to determine the impact on solder volume deposition between Type 3, Type 4 and Type 5 SAC305 alloy powder in combination with stainless steel laser cut, electroformed and the emerging laser cut nano-coated stencils. Leadless QFN and μBGA components will be the focus of the test utilizing optimized aperture designs.

Cleanliness is a product of design, including component density, standoff height and the cleaning equipment’s ability to deliver the cleaning agent to the source of residue. The presence of manufacturing process soil, such as flux residue, incompletely activated flux, incompletely cured solder masks, debris from handling and processing fixtures, and incomplete removal of cleaning fluids can hinder the functional lifetime of the product. Contaminates trapped under a component are more problematic to failure. Advanced test methods are needed to obtain "objective evidence" for removing flux residues under leadless components.Cleaning process performance is a function of cleaning capacity and defined cleanliness. Cleaning performance can be influenced by the PCB design, cleaning material, cleaning machine, reflow conditions and a wide range of process parameters.This research project is designed to study visual flux residues trapped under the bottom termination of leadless components. This paper will research a non-destructive visual method that can be used to study the cleanability of solder pastes, cleaning material effectiveness for the soil, cleaning machine effectiveness and process parameters needed to render a clean part.

For every 10 ℃ increase in temperature, the reaction rate is twice to three times. This means that for every 10 ℃ increase in temperature, the life span of the product will be halved, and when the temperature rises by 20 ℃, the life span of the product will be reduced to 1/4. High temperature will lead to aging, oxidation, evaporation, physical deformation and so on. Low temperature will lead to embrittlement, ice formation, viscosity and solidification degree, loss of mechanical strength, physical shrinkage and so on. When the product is shipped, stored and operated in the environment, it will be endangered. In addition, each product has regulatory and certification requirements, and it is important to evaluate reliability and durability before it is put on the market. In general, according to the IEC60068 test standard, it requires the volume of the laboratory to be at least five times the total volume of the sample under test. Haida constant temperature and humidity box can help you meet this demand.
