【 Mayeso a Solderability (batani losinthira】

Pamwamba pa terminal amalowa mu malata kuwotcherera dziwe 1㎜ chakuya, ndi kutentha ndi 230±5℃, nthawi ndi 3 ± 0.5 masekondi.

Samalani ndi:

(1) Nthawi yowotcherera siyenera kupitilira masekondi atatu.

(2) Malo owotcherera ayenera kukhala oposa 75%.

【Kuyesa kukana kuwotcherera】

Kutentha kwa ng'anjo yowotcherera kumayendetsedwa pa 260 ± 5 ℃, ndipo nthawi ya kuwotcherera ndi 3 ± 0.5 masekondi.Kutentha kwa mbale kuwotcherera ndi 320 ± 5 ℃, ndi nthawi kuwotcherera ndi 3 ± 0.5 masekondi.

Zindikirani: ayenera kukhutitsidwa ndi thupi popanda mapindikidwe, makina ndi mphamvu zamagetsi.

【Mayeso a moyo】

Palibe katundu: Wogwiritsa ntchito samayesa miyeso ya 100,000 pamlingo wa 60 pa mphindi.

Samalani ndi:

(1) Kukaniza kukhudza sikungapitirire 200m ω

(2) Zina, zokhutira ndi ntchito zamakina ndi zamagetsi.

【Kuyesa kukana kutentha】

Pambuyo pa kuyesedwa kwa maola 96 pa 85 ± 2 ℃, idayikidwa pamalo otentha kwa ola limodzi.

Zindikirani: palibe mawonekedwe osinthika okhazikika, okhutitsidwa ndi ntchito zamakina ndi zamagetsi.

【Kuyesa kukana kuzizira】

Chitsanzocho chinayikidwa m'malo a 90 ~ 96 madigiri achinyezi a 40 ± 2 ℃ kwa maola 96, kenako anaikidwa pamalo abwino kwa ola la 1 asanayesedwe.

Zindikirani: palibe chowoneka bwino, chokhutitsidwa ndi ntchito zamakina ndi zamagetsi.

【Kunyowetsa mayeso】

Anayika 40 kuphatikiza kapena kuchotsera 2 ℃.Chinyezi chachibale cha 90 ~ 96 madigiri mu chilengedwe pambuyo pa maola 96, ndiyeno ikani chitsanzocho pamalo abwino kwa ola limodzi pambuyo pa mayeso.

Zindikirani: palibe chowoneka bwino, chokhutitsidwa ndi ntchito zamakina ndi zamagetsi.

Pambuyo pa mayesowa, titha kupeza moyo wothandiza wa batani losinthira, mtundu wa chinthu chomalizidwa, ndiyeno tiyeni tigwiritse ntchito batani lotsimikizika kwambiri.
