If you want to solder the supercapacitors or ultracapacitors from Tecate Group (for example: TPL-70/18X45F or TPLH-2R7/75WR18X40, then it is recommended to go through the manufacturer’s guidelines first:
General Guidelines:
While dipping the leads of the capacitor, do not dip the entire ultracapacitor body into melted solder.
When soldering the capacitor on the board, make sure the sleeving and body of the ultracapacitor does not touch any other component, with the exception of another
ultracapacitor.
Excessive heat during soldering may cause the sleeve to shrink or crack and may also compromise the reliability of the cell. Do not exceed 70°C cell body temperature as this may damage the ultracapacitor.
The lead material is steel core, clad with copper (30-45um depending upon the lead diameter) and plated with Tin (~11um).
Provide appropriately spaced holes to ensure proper mounting to the specified cell dimension in order to minimize mechanical stress on theterminal leads.
Use of a protective coating for components on the PCB is strongly recommended to mitigate potential risk of the components being damaged in an event of electrolyte leakage.
Board layout should take into account that the cell is not hermetic and during its lifetime electrolyte vapor and gases generated during normal operation may escape the package.
Hand Soldering
Warning: Do not touch the ultracapacitor external sleeve with the soldering iron which can cause the sleeve to melt or crack.
The recommended temperature of the soldering iron tip is less than or equal to 350°C.
The soldering duration should be shorter than 3 seconds. Minimize the time that the soldering iron is in direct contact with the terminals of the ultracapacitor as excessive heating of the leads may lead to higher equivalent series resistance (ESR).
Solder Composition - SAC 305: Sn 96.5%, Ag 3.0% and Cu 0.5% alloy
Flux – Use a halide free, activated rosin-based flux
Maximum contact time with component leads – 10 seconds
NOTE: Do not exceed 70°C cell body temperature as this may damage the ultracapacitor.
Wave Soldering
Recommended Solder Pot Temperature – 248°C / 478°F
Solder Composition – SAC 305: Sn 96.5%, Ag 3.0% and Cu 0.5% alloy
Recommended Fluxes – Water soluble flux, Kester 2331ZX or equivalent, or a Low Solids VOC-free No-Clean flux comparable to Kester 979T
Recommended Preheat – Preheat board from bottom side only, bring top of board to 100C maximum immediately before soldering, preheat time will depend upon heating efficiency. Use a maximum preheating time of 60 seconds for PC boards 0.8 mm or thicker. Use the following table for wave soldering on leads only:
NOTE: Do not exceed 70°C cell body temperature as this may damage the ultracapacitor.”
Reflow Soldering
Reflow soldering should not be used on the ultracapacitors.
Circuit Board Cleaning
Circuit boards can be immersed or ultrasonically cleaned using suitable cleaning solvents for up to 5 minutes and up to 60° maximum temperatures. The boards should be thoroughly rinsed and dried.
Suitable cleaning solvents include Pine Alpha ST-100S, Sunelec B-12, DK be clear CW-5790, Aqua Cleaner 210SEP, Cold Cleaner P3-375, Telpen Cleaner EC-7R, Clean-thru 750H, Clean-thru 750L, Clean-thru 710M, Techno Cleaner 219, Techno Care FRW-17, Techno Care FRW-1, Techno Care FRV-1, IPA (isopropyl alcohol), deionized water. The use of ozone depleting cleaning agents is not recommended in the interest of protecting the environment.
