Every repair shop knows this moment: a customer drops off a phone with a torn display flex or a lifted pad next to the charging IC, and your regular conical tip covers too much area. The YCS C210 Iron Head Set 4K+6I 10Pcs solves that problem at the tip level, giving you ten small replaceable heads that plug into the YCS C210 replaceable-tip core instead of forcing you to buy a full C210 cartridge every time a point wears down. The pack splits into two working shapes, six I-type needle heads and four K-type knife heads, and each shape handles a different part of the micro soldering job. The I heads carry an ultra-fine point that lets you place heat on a single tiny SMD component, a broken trace, or one pin of a connector without disturbing the parts next to it, which matters when you run jumper wire on a screen flex line, rebuild a missing pad under the microscope, or bridge a cut trace after liquid damage. The K heads give you a flat blade edge with more thermal mass, so you can drag solder across a row of FPC connector pins, tin BGA pads after removing a CPU or eMMC, scrape old solder off the board, and clean pads before reballing. Because both shapes sit on the same C210 platform, you switch from fine jumper work to pad cleaning in seconds and keep your workflow moving instead of swapping full cartridges. Each head uses a copper core that carries heat quickly from the C210 heating element to the working point, so the tip recovers fast when it touches a ground plane or a large shield pad, the classic spot where cheap tips go cold and leave a dull joint. Multi-layer electroplating protects the surface from oxidation, so solder wets cleanly and the point keeps its shape longer, as long as you tin the head before switching the station off and wipe it on brass wool rather than a dry sponge. The plug-in design lets you remove a worn head by hand and press a new one into place, with a firm fit that keeps the point steady during fine work. On the repair bench, this set fits right after diagnosis: once your multimeter or DC power supply points to a short, a dead phone, a charging issue, or a display problem, and you trace the fault to a damaged line or a failed component, the I heads take over the precision side while the K heads prepare the board for IC replacement. Pair the set with a hot air station for component removal, a stereo microscope for jumper work, a PCB holder to keep the board flat, and quality flux with thin solder wire for clean joints, and if you plan to move into full CPU and eMMC rework, a reballing kit with a matching stencil completes the setup. Shop owners in Lahore, Karachi, Islamabad, and across Pakistan burn through tips quickly during busy seasons, and a ten-piece pack keeps spare heads ready so a worn point never stops a job halfway. For technicians who already run a C210-format station, the YCS C210 Iron Head Set 4K+6I 10Pcs offers a low-cost way to keep sharp, specialized points on hand for screen jumper wire, Face ID flex repair, FFC cable repair, and motherboard trace work. A few practical habits stretch tip life further: set the temperature only as high as the joint needs, use a good flux on modern lead-free boards, never scrape the plated surface with a blade, and store spare heads dry and sealed. If you are searching for C210 replaceable tips price in Pakistan, KB GSM Store stocks this set alongside soldering stations, hot air stations, microscopes, and reballing tools, so you can build a complete micro soldering bench from one place.
