We hold the part in the USA, so a chip-level repair on an A2 does not sit waiting on a shipment. The chip is not sold on its own: it is fitted at component level, the board is read chip by chip on our own tester afterwards, and it goes back proved under load.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eSEAL02 is Bitdeer's own SHA-256 ASIC, fabricated at TSMC and used in no other manufacturer's hardware. A Sealminer A2 hashboard carries 153 of them, 459 in a complete machine, and Bitdeer publishes no datasheet, no distributor part number and no spare-parts channel for the chip or the board it sits on. For most of this machine's life the only answer to a dead chip was a repair ticket with the factory. Having the part on the shelf is what turns that into an ordinary bench repair with a date on it.\u003c\/p\u003e\n\n\u003ch2\u003eHow this add-on works\u003c\/h2\u003e\n\n\u003cp\u003eOne chip is already covered by the \u003ca href=\"\/products\/sealminer-a2-hashboard-repair-service\"\u003eSealminer A2 hashboard repair\u003c\/a\u003e itself. This line is for the ones after that: when diagnostics come down to more than a single failed SEAL02, it covers the part and the work of fitting each additional chip, one add-on per chip. It attaches to the repair and cannot be ordered on its own — a chip in an envelope does not fix a board, and nothing is replaced on your board before you have heard the count and agreed to it.\u003c\/p\u003e\n\n\u003ch2\u003eWhat the part is\u003c\/h2\u003e\n\n\u003ctable style=\"width:100%;border-collapse:collapse;table-layout:fixed;font-family:sans-serif;font-size:14px;margin:16px 0 24px;\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:32%\"\u003e\n\u003ccol style=\"width:68%\"\u003e\n\u003c\/colgroup\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color:rgb(248,248,248);border-bottom:2px solid rgb(238,238,238);\"\u003e\n\u003cth style=\"padding:12px;text-align:left;vertical-align:top;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:12px;text-align:left;vertical-align:top;\"\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"border-bottom:1px solid rgb(238,238,238);\"\u003e\n\u003ctd style=\"padding:12px;vertical-align:top;word-break:break-word;\"\u003ePackage marking\u003c\/td\u003e\n\u003ctd style=\"padding:12px;vertical-align:top;word-break:break-word;\"\u003e\n\u003ccode style=\"word-break:break-all;\"\u003eSEAL02\u003c\/code\u003e on the first line, with a lot and date code underneath that differs from batch to batch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"border-bottom:1px solid rgb(238,238,238);\"\u003e\n\u003ctd style=\"padding:12px;vertical-align:top;word-break:break-word;\"\u003eMade by\u003c\/td\u003e\n\u003ctd style=\"padding:12px;vertical-align:top;word-break:break-word;\"\u003eBitdeer's own design, fabricated at TSMC.

The A2 never shows its owner one: the User Panel lists the three boards with a hashrate and a temperature each, so what you see is a board sitting at zero, or one that has settled below its neighbours and never recovers. The count exists, and we read it — on HashProbe, the tester we built for this board, all 153 chips answer or they do not, and the ones that do not are named. Because the chips sit in groups of three, one dead chip commonly takes its two neighbours off the air with it, which is why a board can lose far more rate than a single failure sounds like. What the miner shows and what each symptom means is set out on the \u003ca href=\"\/products\/sealminer-a2-hashboard-repair-service\"\u003eSealminer A2 hashboard repair\u003c\/a\u003e page.\u003c\/p\u003e\n\n\u003ch2\u003eBefore you assume it is a chip\u003c\/h2\u003e\n\n\u003cp\u003eA board that fades as the machine warms and comes back after a night off is usually a thermal path problem rather than silicon. A machine that restarts a few minutes after reaching full rate may be the board or may be what feeds it, and from the dashboard those look identical. Either way the chip count on the bench settles it before any part is fitted. One more thing worth knowing: Bitdeer lists SEAL02 for the A2 Pro as well, but we have not had a Pro board on the bench, so ask before assuming the part and the work transfer to it.\u003c\/p\u003e\n\n\u003cp\u003eAll repairs are performed personally by Alex, who has been servicing ASIC miners since 2019. \u003ca href=\"https:\/\/antminer-repair.com\/pages\/aleksandr-muranov\"\u003eSee credentials →\u003c\/a\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003ca href=\"https:\/\/antminer-repair.com\/pages\/contact\"\u003eContact our repair team today and get your miner back to full power.\u003c\/a\u003e\u003c\/p\u003e","brand":"Bitdeer","offers":[{"title":"Default Title","offer_id":67735511499025,"sku":"CHIP-SEAL02","price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0788\/4917\/9921\/files\/seal02-asic-chip-sealminer-a2-macro_a4b1ed43-a598-4158-8a4b-1f263afb678d.webp?v=1792039831","url":"https:\/\/antminer-repair.com\/products\/seal02-asic-chip-sealminer-a2","provider":"Antminer Repair","version":"1.0","type":"link"}
