product description chem - wik ? rosin is especially designed for today?s heat sensitive electronic components. the lighter mass, pure copper braid construction allows for better thermal condu ctivity, even at low temperatures. chem - wik ? rosin responds as much as 50% faster than conventional desoldering braids. this design minimizes overheating and requires less ?contact? pressure for greater operator control. all sizes are coated with a type ?r? organic flux system. ? requires little or no post solder cleaning ? no corrosive residues ? optimized weave design for faster wicking and heat transfer ? halide free ? minimal risk of heat damage to components and circuit boards typical applications chem - wik ? rosin desoldering braid safely removes solder from: ? thru - hole components ? surface mount device pads ? bga pads ? micro circuits ? terminals ? lugs and posts ? identification script typical product data and physical properties chem - wik ? rosin flux type: grade ww, type ?r? clean - up required : no military specifications : mil -f-14256f shelf life ? 2 years from manufacturer date part # size inches size metric 2 - 5l .030? .76mm 5 - 5l .050? 1.27mm 7 - 5l .075? 1.91mm 10 - 5 l .100? 2.54mm static dissipative packaging static dissipative packaging is available on all 5 foot bobbins. the static dissipative bobbins qualify as electrostatic discharge protective per dod standard 1686 and dod handbook 263. meets the static dela y rate provision of mil -b- 81705c. tds # cwik chemtronics technical data sheet chem - wik ? rosin
usage instructions for industrial use only. read msds carefully prior to use. 1) choose a chem - wik ? desoldering braid width equal to or slightly larger than the pad or connection. 2) choose a solder iron tip equ al to or slightly smaller than the pad or connection. 3) set temperature of iron between 600 - 750f 4) place wick on solder joint and place tip of hot iron on top of wick 5) as solder becomes molten, the color of the wick will change from copper to silv er. 6) remove wick and iron from solder joint simultaneously once color change has stopped. 7) the component lead is now clean and free from solder. 8) clip and discard the used portion of the wick. availability width color code 5 ft. bobbin 25 ft. spool 50 ft. spool 100 ft. spool 500 ft. spool .030? white 2 - 5l 2 - 25l 2 - 50l 2 - 100l 2 - 500l .050? yellow 5 - 5l 5 - 25l 5 - 50l 5 - 100l 5 - 500l .075? green 7 - 5l 7 - 25l 7 - 50l 7 - 100l 7 - 500l .100? blue 10 - 5l 10 - 25l 10 - 50l 10 - 100l 10 - 500l chem - wik ? rosin is design ed to meet or exceed the following standards: mil - f - 14256f, type r mil - std - 2000a mil - b - 81705c nasa nhb5300.4(3a) nasa sp - 5002 nasa npc200 - 4 ipc sf - 818 dod handbook 263 dod standard 1686 bellcore tr - nwt - 00078 technical & application assistance chemtronics provides a technical hotline to answer your technical and application related questions. the toll free number is: 1-800-tech-401. note: this information is believed to be accurate. it is intended for professional end users having the skills to evalu ate and use the data properly. chemtronics does not guarantee the accuracy of the data and assumes no liability in connection with damages incurred while using it. chemtronics 8125 cobb center drive kennesaw, ga 30152 1- 770- 424- 4888 rev. d ( 08/13 ) distributed by:
