SHENMAO SMF-WB02 / SMF-WB51 Water Soluble Flux are made locally in the USA and with the same quality in 9 other worldwide locations. It is said their Low Viscosity (easy to apply), High Tackiness (slump resistant), consistent printability for BGA and Micro BGA Ball Assemblies and excellent wash ability after high temperature reflow (255ºC and 60 sec over 220ºC) create highly reliable Solder Joints with optimum maximized Quality.
EKT AOI machine application: inspection after stencil printing, pre/post reflow oven, pre/post wave soldering?FPC etc. Stencil printing: Solder unavailability, insufficient or excessive solder, solder misalignment, bridging, stain, scratch etc. Compo

The evolution of internet-enabled mobile devices has driven innovation in the manufacturing and design of technology capable of high-frequency electronic signal transfer. Among the primary factors affecting the integrity of high-frequency signals is the surface finish applied on PCB copper pads – a need commonly met through the electroless nickel immersion gold process, ENIG. However, there are well-documented limitations of ENIG due to the presence of nickel, the properties of which result in an overall reduced performance in high-frequency data transfer rate for ENIG-applied electronics, compared to bare copper. An innovation over traditional ENIG is a nickel-less approach involving a special nano-engineered barrier designed to coat copper contacts, finished with an outermost gold layer. In this paper, assemblies involving this nickel-less novel surface finish have been subjected to extended thermal exposure, then intermetallics analyses, contact/sheet resistance comparison after every reflow cycle (up to 6 reflow cycles) to assess the prevention of copper atoms diffusion into gold layer, solder ball pull and shear tests to evaluate the aging and long-term reliability of solder joints, and insertion loss testing to gauge whether this surface finish can be used for high-frequency, high density interconnect (HDI) applications.

SHENMAO PF606-P133 Solder Paste is designed for selective laser soldering on tiny solder joints (1.5mm or smaller), especially on expensive, temperature-sensitive components and assemblies. In the past, such a small solder joint is not suitable for standard reflow processes and has to be soldered manually. With PF606-P133 Solder Paste, automatic laser soldering can easily be accomplished.
