Soldering and Desoldering Tips Important notice: special care for soldering tips! Hand soldering operators are happy when their soldering tips last a long time and continue to solder well. Soldering tips that do not allow the solder to melt rapidly due to excess oxidation clearly disrupt productivity! Special care of the soldering tip should be taken in order to solder efficiently. Important Facts: 1. When a soldering tip remains hot for a long period of time, the tip will oxidize or blacken. An oxidized tip will no longer „wet“ or melt solder properly. 2. The higher the working temperature of the soldering tip, the faster this oxidation will take place and tip lifetime will be shorter. 3. Soldering irons that automatically go into a lower “stand-by” temperature increase tip life. 4. The oxidation of the tip will be very rapid if the tip is left “cooking” without molten solder covering the tip end. It happens, for example, if the tip is not wettned with solder right after cleaning it. The ERSA Tip-Reactivator allows the regeneration of oxidized soldering tips. It is environmentally safe, free of lead and halogens and func-tions even at low soldering tip temperatures. For this purpose the heated soldering tip is wiped on the surface of the regeneration compound. 5. Excessive mechanical force during soldering will shorten the tip life. 6. Proper care of the tip will greatly increase tip life. 7. Lead-free soldering requires higher temperatures, is more aggressive to the tip and will always lead to shorter tip life. Nickel-plating Special Care: The base material made of highly conductive electrolytic copper ensures unhindered heat transfer from the heating element to the ERSADUR LF coating ERSADUR LF coating (up to 600 micron) of iron-plating (subject to type of tip) is factory pre-tinned with lead-free solder at working end Nickel-plating 1. Always clean the tip by wiping on a slightly wet sponge after each use. Alternatively, tips can be dry cleaned using wire mesh. 2. Always put fresh solder onto the end of the tip BEFORE putting the tip back into the iron holder. 3. Always use lowest working temperature possible. 4. Never leave an iron “cooking” unattended for some time. Always set iron into automatic stand-by if possible or turn-off when not in use. 5. Never use excessive mechanical force when soldering. Iron-plating Chrome-plating prevents corrosion and solder collection on undesirable spots Cross-section of an ERSADUR soldering tip, non-scale representation 6. Soldering tip oxidation can be easily removed if detected early. Early detection and removal will greatly increase tip life. 7. Tip oxidation removal or tip refurbishing is accomplished in 4 consecutive steps: a. clean on damp sponge, b. clean with wire brush, c. using a Tip re-activator chemical, and d. re-tinning using proper flux cored solder wire. ERSADUR LF soldering tips to process lead-free solders Conventional soldering tips can also be used for lead-free solders. Since lead-free soldering requires higher process temperatures, and due to the fact that lead-free solder is more aggressive to the soldering tip, the tip’s service life is shorter. ERSADUR LF soldering tips have an increased layer of iron, which increases tip life. Consequently they are especially suitable for lead-free soldering. 36 Your Guide 422 ERSADUR Desoldering Tip Series 0422FD10 0422ED 0422FD3 For: • DIGITAL 2000 A with Chip tool • MICRO-CON 60 iA SMD Desoldering Pincette 40 • REWORK 80 4 mm, for e.g. SO 8 GT/14 GT/16GT 6 mm, for e.g. SOIC 8 7,5 mm, for e.g. SOIC 12 / SOT 23 0422FD1 0422FD4 0422FD2 10 mm, for e.g. SOIC 16 12.5 mm, for e.g. SOIC 20 15 mm, for e.g. SOIC 24 0422FD5 0422FD6 0422FD7 17.5 mm, for e.g. SOIC 28 20 mm, for e.g. SOIC 32 25 mm, for e.g. SOIC 40 0422FD8 0422FD9 0422QD5 27.5 mm, for components of 27.5 mm side length 40 mm, for components of 40 mm side length 90°, length 10 mm, for e.g. PLCC 20 0422QD1 0422QD6 0422QD3 90°, length 12.5 mm, for e.g. PLCC 28 90°, length 15 mm, for e.g. QFP, TQFP and TQFP 0T25 90°, length 17.5 mm, for e.g. PLCC 44 0422QD4 0422QD2 0422QD7 90°, length 20 mm, for e.g. PLCC 52 90°, length 25 mm, for e.g. PLCC 68 90°, length 30 mm, for e.g. PLCC 84 0422RD1 0422RD2 0422MD length 22.5 x 16.5 mm, for e.g. QFP 100 length 15 x 12.5 mm, for e.g. PLCC 32 ellipse, for MELF and MINIMELF • SMD 8000 • SMT UNIT 60 AC / A with Chip tool / SMD Desoldering Pincette 40 0422SD* *Please note: The desoldering tips 0422SD must be used in combination with the tip turn protection set (see page 24) to ensure good results.
