about Surface Mount Reflow Technology email：susan@xmjuda.com
Surface Mount Reflow
The latest PCB assembling method makes use of solder paste technology to directly mount the components into the board pads. In this manner, narrower spacing between components is allowed. Miniaturization of electronic devices paved the way for this type of printed circuit board assembly as smaller pads, smaller packages and smaller circuitry can be utilized. Even if surface mount technology corresponds to significant benefits, some applications still require through-hole technology or mixed assembly techniques. This includes power supplies wherein transformers and capacitors would require mechanical strength from THT.
The Advantages of Surface Mount Technology email：susan@xmjuda.com
Surface Mount Technology offers numerous advantages which enable the production of smaller devices with higher functionality. More PCB circuit board assembly manufacturers are willing to use SMT than THT. Explained below are the detailed benefits that can be gained with SMT processes.
Smaller and Lighter Packages. With SMT, components can be directly mounted more closely spaced with thinner leads. Holes do not need to be drilled unlike with the THT process. This results in smaller and lighter packages.
Higher Pin or Lead Counts. Surface Mount Technology allows higher I/O counts with more pins and leads to be sold onto the PCB surface.
More Functionality. Since SMT can be used for higher pin or lead counts, interconnection per area is more maximised.
High Frequency Operations. With a higher packaging density design, SMT gives room for shorter connection paths leading to higher frequency options.
about Vapor Phase Reflow and Perfluoropolyether PFPE JHLS Series email：susan@xmjuda.com
In the landscape of SMT reflow soldering, Vapor Phase Reflow stands out as the benchmark for achieving ultimate soldering uniformity and reliability in oxygen-sensitive, high-value assemblies. This superior process is fundamentally enabled by a critical material: the specialized working fluid that creates the inert vapor blanket.
JHLS series Perfluoropolyether is precisely this essential component. It is the high-purity, thermally stable fluid that, when heated, generates the perfectly uniform, oxygen-free saturated vapor zone. This unique environment ensures consistent latent heat transfer for flawless soldering while completely protecting sensitive components and pristine solder joints from oxidation. Without a premium PFPE fluid like JHLS series, the distinct advantages of the Vapor Phase Reflow process-its exceptional consistency, yield, and reliability-cannot be realized, making it the indispensable foundation of this advanced manufacturing technique.
PFPE liquid JHLS series is not just a passive fluid; it is the foundational material that makes this superior process possible. Its engineered properties provide a comprehensive suite of benefits:
1. High purity and no residue characteristics
The JHLS series perfluorinated fluid uses advanced perfluorinated technology to ensure that the product has extremely high purity. During the vapour phase soldering, the fluid will not produce any impurities, thus avoiding contamination of electronic components.
2. Excellent thermal conductivity
During the soldering process, uniform heat distribution is crucial. The JHLS series perfluoropolyether pfpe has excellent thermal conductivity, which can ensure uniform heat transfer in the soldering area and reduce component damage caused by thermal stress.
3. Low surface tension and fast penetration
The low surface tension of the JHLS series perfluoropolyether oil enables it to quickly penetrate into tiny gaps, ensuring full coverage of the soldering area. Whether it is a complex multi-layer PCB or a micro BGA package, the JHLS series can provide precise soldering results.
4. Long-life design
The design life of the JHLS series perfluorinated polyether oil far exceeds that of ordinary soldering fluids, reducing replacement frequency and maintenance costs. At the same time, its high-efficiency performance can reduce soldering defect rates and improve production efficiency.
5. Environmental protection and safety features
The JHLS series perfluoropolyether oil fully complies with international environmental standards such as RoHS and REACH, does not contain any harmful substances, and is harmless to the human body and the environment.
