Avalon A3206 Chip Tin Station - Complete Kit for 921 Miner ASIC Chip Repairs

Avalon A3206 Chip Tin Station Kit | Complete Reballing Set for Avalon 921 Miner ASIC Repair

The Avalon A3206 chip tin station is a complete reballing fixture for the Canaan AvalonMiner 921 (also known as A9) — the SHA-256 Bitcoin miner released September 2018 with 20 TH/s hashrate at 1700W (85 J/TH efficiency). The full miner runs 104 × A3206 ASIC chips distributed across the hashboards, so any chip-level failure in the field maps to one of those 104 positions and requires precision reballing to recover.

The kit pairs a ±0.01mm laser-cut steel stencil plate with a secure chip holder, eliminating the two most common ASIC repair failures: chip damage during placement and false (cold) soldering joints. False soldering on an A3206 produces an intermittent connection that passes initial power-on but fails under thermal stress — the exact symptom that drives repeat repair visits if the first reballing was sloppy.

Where the A3206 Tin Station Fits in 921 Repair

• Avalon 921 (A9) hashboard repair — reball failed A3206 chips at any of the 104 chip positions.
• Hashrate drop below 20 TH/s — chip failure on one or more positions; identify with test fixture and reball.
• Chip-level recovery — recover salvageable A3206 chips from scrap boards for reuse.
• Production repair benches servicing legacy Avalon 921 fleets in low-power-cost regions where the miner is still profitable.
• Standard recovery from "no nonce found" — Avalon 921 hashboard error signature pointing to a dead chip on the chain.

Construction and Workflow

• ±0.01mm laser-cut precision stencil — matches the A3206 BGA pad pitch exactly.
• Heat-resistant alloy chip holder — clamps the chip in fixed orientation during paste application.
• High-grade steel + alloy construction — withstands SAC305 reflow profiles without warping.
• Reusable across hundreds of cycles with proper IPA cleaning between uses.
• Standard reballing workflow: lift failed chip → clean pads → clamp chip in holder → lay stencil → apply paste → reflow → place reballed chip on board → reflow.

Avalon A3206 Tin Station Specifications

FAQ — Avalon A3206 Tin Station

Q: How many A3206 chips per Avalon 921 hashboard?
A: Each Avalon 921 miner runs 104 A3206 chips distributed across its hashboards. Chip-level failure on a single position typically reduces the board to a low-hashrate or zero-hashrate state until the failed chip is replaced or reballed.

Q: Does the A3206 tin station fit Avalon 1066 / 1166 / 1246 hashboards?
A: No — those newer Avalon models use the A3205 (A1066), A3206-series variants (A1166), or A3206S / A3208 chips on the A1246. Each chip family has its own BGA footprint and requires its own dedicated tin tool. Check related products for the A3205 tin tool (A1066 / A1046 / A1047).

Q: What rework profile?
A: Standard BGA reflow — preheat hashboard to 100-150°C, ramp to peak ~240-250°C, hold 30-60 seconds, controlled cool-down. Use flux paste, clean pads with IPA between heat-up and chip-place.

Q: How do I diagnose which A3206 failed?
A: Start with rail-level measurement (±10V power-domain test) to identify which voltage domain dropped, then test individual chips within that domain. Most repair-bench test fixtures will identify the failing chip position automatically.

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