Taśma Poliimidowa

The 0.5" width is perfect for covering a row of millmax pins without any overhang mess. It sticks firmly while I solder but peels off cleanly afterward, and the heat resistance held up through several passes.

The 0.5" width fits perfectly between those millmax pins without any overlap, and it peels off clean with zero sticky residue left behind. I used it to mask off two full rows and the heat resistance held up exactly as promised.

Finally, a spool that doesn't fight you halfway through a row of millmax pins—the 0.5" width lays flat and stays put under the iron. I've used cheaper amber tapes that bubbled up, but this one held its edge through the whole board.
