Hakko prides itself in the consistently high quality of the materials and workmanshipthat go into its products, which include our various soldering and desoldering tips.Hakko tips are designed and manufactured for maximum heat conductivity,performance, and life.

TIP MAINTENANCE AND CLEANING PROCEDURES

SELECTING THE PROPER TIP FOR THE JOB.– Short tips with larger dimensions will provide better heat transfer and

performance than longer, thinner tips.

– One common problem is not matching the tip size to the job. This cancause a drop in the performance of your soldering irons and affect thereliability of your work.

– Matching the tip size and configuration to the job is as important as anyother aspect of soldering, and in many cases is more important. Alwaysuse a tip as wide and thick as possible, making sure that it does notinterfere with components or overlap the pad and touch the board.

KEEP TIPS WET.– Applying solder to the working surface of the tip will prevent oxidation and

impurities from building up. This promotes long tip life.

KEEP TIPS CLEAN.– Stroking the tip surface across a clean and properly damp cellulose

sponge will keep flux residues, solder impurities, and oxidation fromforming on the surface of the tip. Immediately re-wet the tip with solderafter wiping, or before any extended period when the iron will not be used.

PROBABLE CAUSES OF EARLY TIP FAILURE

HIGH LINE VOLTAGE.

– Even though Hakko irons and stations are designed to maintain temperature withslightly varying supply voltages, a consistently high line voltage will cause the iron torun hot. This will reduce tip life.

LOW TIN ALLOY SOLDER.

– The lower the tin content of your solder, the more difficult it will be to keep the tip from‘dewetting’ (losing its protective coat of solder). Keep a roll of large diameter 63-37solder on hand to periodically flush and re-tin the tips.

SMALL DIAMETER SOLDER.

– In many cases, the diameter of the solder being used is too small for effective wettingof the tips. A periodic flooding with a larger diameter solder, as mentioned above, willdo the trick.

DIFFERENCES IN FLUX ACTIONS.(RA, RMA, water soluble, ‘No Clean’ etc.)...

– The more active the flux, the more frequently the tip needs to be cleaned. Oxidationforms at a much higher rate with highly active fluxes. Please check with the solder orflux manufacturer as to the relative activity of the flux you are using.

EXCESSIVE PRESSURE, OR THE PUSHING IN OF HEAT.

– Applying excessive pressure, or rubbing the tip against the joint to ‘force’ heat in, willdestroy the tip faster than normal contact soldering.

TIP TEMPERATURE.

– The higher the tip temperature, the faster oxidation will form. At temperaturesexceeding 875 deg. F, the speed of oxidation is just about twice that at 700 deg. F.

NOTE Tips subjected to proper maintenance and cleaning procedures should last between two to fourweeks, depending upon the temperature, tip configuration, and the job or jobs being performed.
