Review: Sequre SQ-D60 Temperature Controlled Soldering Iron
Review: Sequre SQ-D60 Temperature Controlled Soldering Iron

Over the past few years a new class of soldering iron has arisen: a temperature controlled iron no longer tied to a bulky mains-powered base station, but using low-voltage DC power and with all electronics concealed in a svelte handle. First came the Miniware TS100, and then  many more, with slightly different feature sets and at varying price points. We’ve reviewed a few of them over the years, and today we have the most recent contender in the Sequre SQ-D60. It follows the formula closely, but costs only £20 (about $26). This price puts it in an attractive budget category, and its USB-C power option makes it forward-looking over models with barrel jacks. Description over, it’s time to plug it in and put it through its paces.

What’s In The Box?

That's a lot of extra bits for a budget iron!
That’s a lot of extra bits for a budget iron!

In the box, aside from the handle containing the electronics, were a surprisingly comprehensive array of parts and accessories. The handle itself is similarly-sized to its competitors, being only slightly longer than that of Pine64’s Pinecil. The tip supplied was unexpectedly a slanted chisel, so I may have managed to order incorrectly, though since it shares the same tip design as both the TS100 and the Pinecil I have plenty of alternative tips should I need one. Otherwise there was a little bag of hex screws along with a key and a driver for them, a little stand with a sponge, a set of Sequre stickers, a USB-C to barrel jack cable, and a barrel jack-to-XT60 connector for use with LiPo battery packs. These last two cables are a particularly useful addition.

At first sight the tip doesn’t seem to have any means of being fixed into its socket, but a closer inspection reveals that there is a hex screw hiding underneath a silicone finger sleeve that holds it securely when tightened. The handle has a simple enough interface, with just two buttons and a 3-digit, 7-segment display. Powering it up from a 45 W USB-PD power supply, and it heats up to 300 °C in around ten seconds after pressing one of the buttons. My usual soldering temperature is 360 °C, and it has an interface involving long presses of one of the buttons before they become up and down buttons to select the temperature. In prolonged use the handle doesn’t become noticeably warm, and aside from a slight new-electronics-getting-hot smell there was no immediate concern that it might release magic smoke.

An Iron Like Several Others

As far as I could dismantle the iron.
This is as much dismantling as I could do, those silicone buttons were the undoing of the effort.

In use, it’s remarkably similar to the other irons we’ve looked at of similar size and shape. Soldering is straightforward, it’s light and easy to use with plenty of heat. The instruction leaflet has a blow-up diagram of its internals, but it pains me to admit that this iron provided a rare moment in which my tear-down skills were defeated. Unexpectedly the tip is mounted to a sub-assembly that comes away from the main board with a 3.5mm jack, and while this was easy to remove, it proved almost impossible to slide the main board out of the handle tube. The reason was that the two silicone buttons would foul on the display and would not budge despite a lot of coaxing. I could have revealed the board by intentionally destroying either buttons or display, but since I prefer to keep the iron useful I didn’t do that. If similar irons are anything to go by I would expect it to contain a USB-PD chip, an 8-bit microcontroller because it has none of the firmware upgradeable features of the TS100 or Pinecil, and then a MOSFET to control the tip. It’s a tested and reliable formula for these irons.

Should you buy one? If you’re looking for a mini iron with a reasonable feature set and some really useful cables bundled all at a budget price, yes. It’s not as cheap as the super-budget SanErYiGo SH72 that we reviewed early last year, but unlike that iron it has digital control and USB-C. Compare it with the old reliable TS100 and the super-hackable Pinecil, and make up your own minds.
