CHEMTRONICS TDS CWik Technical Data Sheet Chem-Wik Rosin PRODUCT DESCRIPTION TYPICAL PRODUCT DATA AND PHYSICAL PROPERTIES Chem-Wik Rosin is especially designed for todays heat sensitive electronic components. Chem-Wik Rosin The lighter mass, pure copper braid construction allows for better thermal Flux Type: Grade WW, Type R conductivity, even at low temperatures. Clean-up Required: No Chem-Wik Rosin responds as much as 50% faster than conventional desoldering braids. Military Specifications: MIL-F-14256F This design minimizes overheating and Shelf Life 2 years from manufacturer requires less contact pressure for greater date operator control. All sizes are coated with a Type R organic flux system. Requires little or no post solder cleaning Size Size No corrosive residues Part Inches Metric Optimized weave design for faster 2-5L .030 .76mm wicking and heat transfer Halide free 5-5L .050 1.27mm Minimal risk of heat damage to 7-5L .075 1.91mm components and circuit boards 10-5L .100 2.54mm TYPICAL APPLICATIONS Chem-Wik Rosin desoldering braid safely removes solder from: STATIC DISSIPATIVE PACKAGING Static Dissipative packaging is available on Thru-hole Components all 5 foot bobbins. The static dissipative Surface Mount Device Pads bobbins qualify as electrostatic discharge BGA Pads protective per DOD Standard 1686 and DOD Micro Circuits Handbook 263.
