Do not wipe the board at first before putting it in your cleaner. It will leave more paste in your tank, but you won't smear it into every corner of your solder resist. We found that only our stencil cleaner would clean a board properly and leave n

EAST WINDSOR, CT — August 2009 — High-Tech Conversions Inc., a manufacturer of high-quality wiping products and a supplier of consumable items used in cleanrooms, assembly lines, laboratories and manufacturing, announces that its GREEN MONSTER formulation has the abrasion resistance to withstand the high friction caused by the wiping action, the integrity to resist fibers from being pulled off by sticky solder paste, and the toughness to withstand the harsh scraping and grating action caused by the stencil’s apertures.

The success of ball grid array (BGA) placement on electronic assemblies is as much a matter of proper preparation and planning, as it is technique. In some designs, it is more appropriate to apply BGAs using a rework station that isolates the placement of the device, without subjecting the entire assembly to thermal reflow. This is especially beneficial in board constructions where the number of BGAs is limited, and the application of the solder paste is difficult, due to small pitch features that stretch the limitation of the stencil construction. Another application for rework stations, involves very large and thermally conductive BGAs, which will not uniformly reflow with other components on the assembly, and may require special process parameters for their proper placement. The most common use of BGA rework stations are for assemblies requiring BGA removal and replacements due to failures in the initial assembly stage.

Today's consumer electronic product are characterized by miniatuization, portability and light weight with high performance, especially for 3G mobile products. In the future more fine pitch CSPs (0.4mm) component will be required. However, the product reliability has been a big challenge with the fine pitch CSP. Firstly, the fine pitch CSPs are with smaller solder balls of 0.25mm diameter or even smaller. The small solder ball and pad size do weaken the solder connection and the adhesion of the pad and substrate, thus the pad will peel off easily from the PCB substrate. In addition, miniature solder joint reduce the strength during mechanical vibration, thermal shock, fatigue failure, etc. Secondly, applying sufficient solder paste evenly on the small pad of the CSP is difficult because stencil opening is only 0.25mm or less. This issue can be solved using the high end type of stencil such as Electroforming which will increase the cost.
