In either case, the baseline must provide a consistent high-speed solder paste printing method, which considers the fill, snap-off, and cleaning processes. Building on our expertise and testing, this paper will highlight the two trains of thought with specific focus on how low-cost materials ...
Flux is a chemical purifying agent. In soldering metals, flux provides three functions: it eliminates rust from the components to be soldered; it closes air out as a result ending extra rust, and by making easy mix improves dripping individuality of the fluid solder. Soldering Paste Soldering ...
Other factors such as the amount of solder paste used/paste stencil thickness are something of a shared responsibility, while factors such as pad sizes, board layout, and package selection rest squarely with the designer. Detailed discussions of MLCC cracking phenomena and their avoidance are availab...
Solder Paste: Solder paste is applied to prepare the surface for soldering. It enhances the interaction between the component surface and the molder filler material. Now that the types and essential resources of PCB soldering processes are discussed, it is important to choose the right PCB manufa...
a锡膏购进时,要贴上购进日期的标签以区分不同批次,保证“先进先出”的实施。 When the tin paste purchases, must paste on purchases the date the label to differentiate the different raid, guaranteed “advanced leaves first” implementation.[translate]...
Usually, SAC305 solder paste reacts with Cu substrate during heating to generate Cu6Sn5 IMC. To achieve excellent solder joints, some process treatments can be carried out on the Cu substrate to control IMC growth. This article will discuss the soldering effect of SAC305 on different Cu ...

used. To mount a die on the bottom of the package, you would use the die stack editor and set its front pin layer to be bottom and its orientation to be chip-up (not mirrored). Because the IC design is done with the pins on the top, this puts the solder bumps on the correct ...
component consists of thin leads, which are pressed through tiny holes in the substrate & soldered to connection boards in the circuits on the reverse side. In surface-mount technology, J-shaped or L-shaped terminals on every component get in touch with the PCB directly. A solder paste inclu...
