Innosilicon T2T T1668B T1668 ASIC Chips Tin Fixture Stencil Plate

T1668B / T1668 / T1668A Tin Fixture Stencil Plate 100mm | Solder-Paste Tool for Innosilicon T2T Hashboard ASIC Chip Replacement

The T1668B / T1668 / T1668A tin fixture stencil plate is a 70mm soldering aid for chip-level repair on Innosilicon T2T hashboards. Designed to deposit an even, controlled layer of solder paste over the ASIC chip pad array — reducing bridging, voiding, and solder-starved joints during reflow rework. The same stencil works across the T1668, T1668A, and T1668B chip variants found on T2T-family boards.

Used with a hot-air station or chip-level reflow rework station: place the stencil over the chip footprint, scrape paste across the openings, lift the stencil, place the chip, and reflow. Pad-level precision that hand-tinning with an iron simply cannot match — critical when one repair board carries dozens of identical ASIC sites.

When You Need the T1668B Tin Stencil

• Replacing a failed T1668 / T1668A / T1668B chip after diagnostics on a T2T hashboard.
• Re-tinning pads after lifting a dead chip — restores even pad geometry for the next reflow.
• Salvaging working chips from a scrap hashboard for reuse on a recoverable board.
• Bench-level repair throughput — speed and consistency improve dramatically over freehand soldering.

FAQ — T1668B Tin Stencil

Q: Which Innosilicon model is this for?
A: T2T-family hashboards using the T1668, T1668A, or T1668B ASIC chip footprint. The chip pad pattern is shared across the three variants, so one stencil covers all three.

Q: Hot air station temperature for reflow?
A: Use the solder paste manufacturer's profile — typically 220–250°C peak with bottom-side preheat at 130–150°C for proper reflow without thermal shock. Always preheat the entire board before applying top-side heat to avoid PCB warping.

Q: Clean the stencil between uses?
A: Yes — wipe with isopropyl alcohol immediately after use. Dried solder paste in the apertures will cause incomplete deposits on the next chip, leading to opens or starved joints.

Q: Bulk pricing for repair benches?
A: Yes — email contact@lys-sz.com for volume pricing on Innosilicon T2T stencils and matched-set rework kits.
