Avalon A3205 Chip Tin Tool Fixture for A1066 A1046 and A1047 Hashboard

Avalon A3205 ASIC Chip Tin Tool Fixture | A1066, A1046, A1047 Hashboard Reballing

The Avalon A3205 chip tin tool fixture is a precision-machined reballing stencil and positioning frame used for tinning the A3205 hash chip on Avalon A1066, A1046, and A1047 hashboards. The fixture pairs a composite positioning plate with a stainless steel mesh stencil sized to the A3205 BGA pad layout — the tool you reach for when a hashboard chip needs to be removed, reballed, and reinstalled cleanly.

Reballing an ASIC hash chip without a proper tin tool fixture is the single most common cause of failed hashboard repairs: misaligned solder balls, bridging across adjacent pads, and inconsistent reflow all trace back to using improvised tooling. The A3205 fixture eliminates those failure modes by clamping the chip in fixed orientation while the stencil deposits a precise solder-ball pattern matching the OEM pad layout. The result is consistent reballing yields across repair benches.

Where the Avalon A3205 Tin Tool Fits

• Avalon A1066 hashboard — A3205 chip reballing for board repair and chip-level replacement.
• Avalon A1046 hashboard — same A3205 chip family, same tin tool fixture.
• Avalon A1047 hashboard — A3205 chip reballing on the A1047 board variant.
• Chip-level recovery — recover A3205 chips from failed boards for reuse.
• Repair-bench production work — consistent reballing yield across multiple boards per day.

Construction and Use

• Composite positioning plate — heat-stable plastic frame that holds the A3205 chip in precise orientation.
• Stainless steel mesh stencil — laser-cut to the A3205 BGA pad pitch and footprint.
• 1:1 OEM pad alignment — solder ball positions match the original A3205 pad layout exactly.
• Burr-free edges on the stencil openings — clean solder paste release on every press.
• Reusable — clean with isopropyl alcohol between uses; expect hundreds of cycles before stencil wear.

Avalon A3205 Tin Tool Fixture Specifications

FAQ — Avalon A3205 Tin Tool Fixture

Q: How do I use the fixture for reballing?
A: (1) Place the A3205 chip in the composite positioning frame, pads up; (2) Lay the stainless steel mesh stencil over the chip; (3) Apply solder paste with a squeegee; (4) Lift the stencil straight up; (5) Reflow the chip in a reflow oven or hot-air station to form the balls.

Q: Can the same fixture work on A1166 / A1246 hashboards?
A: No — A1166 and A1246 use different hash chips (A3206 / A3208 series) with different BGA layouts. You'll need the corresponding tin tool fixture for those chip generations.

Q: What solder paste do you recommend?
A: Standard SAC305 (Sn96.5/Ag3.0/Cu0.5) reballing paste with appropriate ball size for the A3205 BGA pitch. We can recommend specific brands — email us with your reflow profile.

Q: How long does the stencil last?
A: With proper cleaning between uses (IPA + soft brush), expect 200-500 reballing cycles before stencil openings start to wear and need replacement.

Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com for volume pricing on full Avalon repair tool kits.
