YCS 150°35g Soldering Paste Needle-Type

Every technician knows the moment: the phone came in dead, you traced the hardware fault to a lifted power IC or a dry charging IC, and now the whole repair depends on how cleanly your paste flows under the chip. The YCS 150°35g Soldering Paste Needle-Type gives you a 150°C melting point paste in a 35g needle syringe, so you lay down exactly the amount each pad needs and reflow the joint without cooking the board around it. That lower melting point matters on modern smartphone motherboards. Stacked boards, underfilled CPUs, plastic connectors, and tiny capacitors all sit millimetres from the chip you want to change, and a paste that melts at 150°C lets you work with less hot air than a standard 183°C leaded paste demands. You spend less time heating the area, neighbouring parts stay in place, and you reduce the chance of the phone returning with a new display problem or network issue after the repair. YCS mixes silver particles into this paste to improve electrical conductivity, and that directly targets one of the most frustrating comebacks in any repair shop: the false joint. A cold or weak solder joint under a charging IC or audio IC often passes the first test on your bench and then fails a week later with a charging issue, no sound, or a phone stuck in a boot loop. Better conductivity and a dense, strong bond help you close the job once instead of opening the same phone twice. The needle-type syringe changes how you handle paste on the bench. Instead of scooping from a jar with a pick and smearing extra solder everywhere, you press the plunger and place a small bead directly on the pad, the via, or the end of a jumper wire. On small packages such as power ICs, charging ICs, and audio codecs, that control keeps solder from bridging into neighbouring balls. On SMD components like coils, filters, and capacitors, you tin each pad evenly so the part sits flat when you reflow it. The 35g size suits a busy repair counter: enough paste for many IC change jobs, yet small enough to finish while the paste stays fresh. A typical workflow stays simple. Clean the pads with solder wick and isopropyl alcohol, apply a thin bead of YCS paste from the needle, place the IC with fine tweezers under your microscope, and reflow with your hot air station set comfortably above 150°C. Watch for the moment the chip self-aligns and settles, then let the board cool before you connect it to your DC power supply to check current draw. For BGA chip work, pair the paste with a matching reballing stencil and a PCB holder so the board stays steady while you heat it. The low melting point also helps when you rebuild a damaged pad trace with a jumper wire, because you can tack the wire with a soldering iron at a modest tip temperature and avoid lifting more copper. This paste belongs in the Solder Paste and Soldering Consumables section of your bench, right next to your flux, solder wick, and solder wire. It works hand in hand with Hot Air Stations, Soldering Stations, Microscopes, Reballing Kits, and PCB Holders, and you confirm every joint afterwards with a Multimeter for continuity and short checks. When your shop starts taking heavier board-level jobs such as CPU reballing on dead phones, a preheating platform becomes the natural upgrade, since bottom heat combined with a low-temperature paste gives you even more control over the board. Keep the syringe capped after every job and store it in a cool place, because solder paste thickens and loses flux activity when it sits in heat. Let it reach room temperature before you use it again, and test-dispense a little on scrap before you touch the real pad. Pakistani repair shops handle a heavy mix of Android and iPhone boards every day, and a dependable low-temperature paste removes one variable from that workload. The YCS 150°35g Soldering Paste Needle-Type gives you that consistency at a practical price in Pakistan, whether you run a single repair counter or a full service center bench.
