Qianli DP-05 Hand Polished Glue Removal Blade – Stainless Steel PCB Layering Knife

Board-level repair often comes down to how cleanly you can separate glued layers without tearing pads or lifting tracks. The Qianli DP-05 handles exactly that job. It's a stainless steel blade, laser-cut for edge uniformity and then hand-polished by a skilled craftsman, part of Qianli's DP series of degumming and layering knives built for phone motherboard work.
On the workbench, this blade earns its place during glue removal and rubber shovel work. When a motherboard has adhesive holding shielding layers, connectors, or component brackets in place, the DP-05 slides under that bond and separates it without gouging the PCB surface. That matters when you're prepping a board for IC change karna or getting ready to reflow a chip — one slip with a stiff blade can lift a pad and turn a simple job into a scrapped board.
The blade doesn't come with its own handle. It's designed to attach to Qianli's universal handle, and it also fits other handles that accept a notch of 0.45mm or wider, so if your bench already runs Qianli or compatible pen-style holders, this blade drops straight into your existing toolkit as a replacement or spare. That interchangeability is useful in a busy repair shop where blades wear down or bend faster than handles do, and you want to keep the handle while swapping the cutting edge.
Stainless steel construction means the blade resists corrosion from flux residue, cleaning alcohol, and the general grime that builds up on a repair bench. The hand-polished finish keeps the edge smooth enough for delicate work near sensitive components, rather than a rough factory edge that catches or drags on the board.
For technicians handling dead phone boards, motherboard layering repair, and glue cleaning around IC pads, connectors, and shielding, the DP-05 fits into the diagnostics and disassembly stage of the repair workflow — before reballing, before reflow, before any soldering or rework begins. Getting that separation step right with a controlled blade reduces the chance of hardware fault issues showing up later because of accidental board damage during teardown.
It's a small, low-cost addition to a repair kit, but it's the kind of tool that gets picked up dozens of times a day on a working bench. Pairing it with a Qianli universal handle, a PCB holder, and a microscope for close inspection rounds out a proper board-level workstation, whether you're running a mobile service center or training junior technicians on safe disassembly technique.
