2UUL DA28 FlatCut Solder Pad Underfill Glue Fast Removal Blades (5pcs/box)

When you're prepping a board for IC change or reballing, the glue left under the chip is usually what slows you down. Scrape too hard with the wrong tool and you lift a pad; scrape too soft and the underfill glue just won't budge. The 2UUL DA28 FlatCut blade set solves that exact problem — it's built specifically for cleaning solder pads and PCB surfaces on mobile motherboards without damaging the pad or the trace beneath it.Each box gives you 5 flat-cut blades measuring 37 x 9 x 0.5mm. That thin 0.5mm profile is what makes the difference on your bench: it slides under the IC footprint and lifts hardened underfill glue in one clean pass, instead of you fighting the glue with a thick blade that digs into the board. Whether you're removing black glue, oxidized solder residue, or leftover flux around a CPU or NAND chip, the flat edge keeps contact controlled so you don't nick the copper pads.The blades are made from high-carbon steel, so they hold their edge through repeated use instead of going dull after a handful of boards. That matters when you're running through multiple dead phone repairs in a single day — a blade that stays sharp means fewer changes and more consistent scraping pressure every time. 2UUL also builds in high edge-deformation resistance, so the thin profile doesn't bend or warp mid-scrape, which is a real issue with cheaper flat blades on the market.Each blade ships individually packaged and rust-proof, with a tear-notch design so you can pull one out fast without fumbling for scissors or a knife mid-job. On a busy repair bench where you're switching between boards constantly, that small detail saves real time. The 5pcs/box format means you're not stuck buying a bulk pack when you only need a handful — restock as your workshop uses them up.These blades fit standard scraper handles used across the GSM repair trade, so if you already run a compatible handle on your bench, you can swap blades straight in. Technicians use the DA28 specifically during motherboard cleanup after an IC change, before reballing a chip, or when prepping a board for a new component — anywhere you need to strip old glue or solder pad residue without heat and without risking the trace.For shops handling dead-after-flash boards, boot loop repairs, or hardware fault diagnosis where the board needs a clean physical inspection first, having a reliable scraping blade on hand cuts down the prep time before you even get to the actual fix. It's a small tool, but it's one of those items that ends up on every technician's bench because the alternative — using a generic blade or a knife — risks damaging pads you can't easily repair.If your workflow includes CPU or IC rework, PCB cleaning, or reballing prep, the DA28 FlatCut set is a practical, low-cost addition that keeps your board prep clean and consistent, job after job.
