Aaron,
We purchase tips for the Intelliheat by bulk. Around 20 - 50 tips at a time. It appears PACE put's the tips for the irons through a burn-in cycle. It seems like the ones for the tweezers are not. I am curious if the tips have a high infant mortality or is there some other reason they are cycled? I mentioned with my older Sensatemp, you require a conditioning cycle which is a feature built into my old controller. Are the Intelliheat tips burned in for this reason? We notice that every time we order tips that they take several weeks to deliver. Which again makes me wonder if you are having problems producing them? Are the tips made outside the USA causing the long lead times?
Will the tips for the ADS200 also have long lead times? Do you still have to burn them in before they are shipped?
Just curious. Thanks again for providing us with the inside details.
Joe,
While they look the same as our standard IntelliHeat Tip Cartridges, AccuDrive Tips (ADS200 tips) have an interior heater with a different construction much more difficult to produce than our standard ones. And Helius is correct about the reason we test every tip before it leaves the factory in North Carolina: the last thing we need is another production fiasco like the one that occurred last year! We normally test only 25-40% of IntelliHeat-style cartridges, but 100% of AccuDrive Tips are tested which results in a slight discoloration towards the top of the tip.
Our tips don't have an abnormally high mortality rate, and rarely do our tips stop working due to heater failure. In fact, tip failure is usually caused by normal wear and tear of the plating. In use, the protective iron plating wears through, developing a pit or maybe a crack in the plating. Once there is a pit/crack, the interior copper is exposed and rapidly erodes away, as solder (especially lead-free solder) has a solvent effect on pure copper, dissolving the inner copper until the plating caves in!
How to improve tip life? In general, lead-free alloys have a higher Sn (tin) content which is
much more destructive to iron plating, especially at higher temperatures. We estimate that solderers using lead-free alloys will go through tips up to 3 times faster than leaded alloys. Here is a common sense list of things you can do to extend tip life:
- Turn down the heat! Probably the best advice I can give. As stated before, using lead-free soldering along with elevated temperatures is a recipe for shorter tip life.
- Do not apply pressure to the soldering iron: being heavy handed with your iron can cause stress cracks in the iron plating.
- Do not scrub the lead: Any type of abrasion can increase your chances of scratching the plating
- Do NOT use tips as screwdrivers!
- With lead-free solder use Brass Wool Cleaner: Yes, it's slightly abrasive, but lead-free alloys and fluxes may require a bit more to properly clean. With Tin-Lead alloys, use a wet sulfer-free sponge (NO household sponges).
- Apply solder to the joint or lead, not the tip: In other words, use a solder-bridge, as constant application of wire solder to the tip may create a pit.
- Cover working end with solder during idle periods: the solder coating will oxide, rather than the iron plating.
- Turn off iron when not in use: less heat equals less oxidation
- Do NOT use pliers to change tips: Especially PACE tip-heater cartridges - it's a sure way to crush the heater core within the cartridge. Use our Tip Tool or Tip Removal Pad instead.
- Use soldering iron system with “Setback” and/or “Auto-Off” feature: Our Instant SetBack (ISB) Tool Stand automatically “sets-back” temperature to 350F/176C when placed in the Stand.
The burn-in or conditioning cycle for the SensaTemp handpieces (
not tips used in SensaTemp handieces) are the result of the construction of SensaTemp heaters. To manufacture SensaTemp heaters, we machine out a brass bobbin, a coated heater wire is wound around the bobbin, then attached to a platinum RTD sensor in the front. It's the coated heater wire which is the cause of the burn-in procedure: when initially heated up, the wire burns off the coating -- you'll notice smoke and an odor after initial heat-up. It's totally normal and the smell/smoke goes away within a short period of time, never to occur again. We recommend burning in the handpiece heaters because there is a very slight chance (probably 1 in 200) of a short in the wire winding if someone turns a brand new heater up to 900F. The vast majority of reported heater shorts occur with our TJ-70 ThermoJet Hot Air Jet Handpiece, probably because that tool is designed to be used at max temperature (900F). In contrast, the IntelliHeat and AccuDrive Tip Heater Cartridges are
not burned in, they are tested. They are placed in a test fixture which fully energizes the tip for about 5 seconds, enough time for the tip to reach solder melt temperatures.
Concerning lead times, you can blame your local distributor for that! Our standard lead times to Distributors for
all PACE products is 2 weeks after receipt of order. This a hard and fast policy of PACE's. We expect distributors to do the one thing distributors are supposed to do:
STOCK OUR PRODUCTS! But many distributors do not. If a distributor takes more than 16 days to ship PACE products or tips, it's very simple: You can bet they are not stocking tips and are only ordering
AFTER you have placed your PO! If you order directly from PACE's website, we generally ship within 2-4 days. Yes, we have occasional lead time issues, and if a production problem occurs (like the original defective batch of ADS/AccuDrive tips), then we are at fault for the delay. But we have been pretty steady on lead times since late August, so I'm going to blame the distributors!
Finally, we manufacture all soldering products (including tips) and bench top rework stations in Vass, North Carolina, while higher end BGA Rework Equipment and Fume Extractors are manufactured in Elkridge MD (where I am located). PACE is one of the last major manufacturers of soldering irons made in the USA (Weller: made in Mexico & Germany; Hakko: made in China; Metcal: Made in China).
Whew, I'm going to bed!
Best,
Aaron
