Tikagula chakudya adzayang'ana kupanga tsiku ndi alumali moyo pa ma CD, chimodzimodzi, terminal chipika zolumikizira amakhalanso ndi nthawi inayake ntchito otetezeka.Zogulitsa zotsalira zomwe zimasungidwa m'malo ena achilengedwe kwa nthawi yayitali, zinthuzo zimatha kusintha, magwiridwe antchito amatsikanso, nthawi yayitali yoyika pambali, kudalirika kwazinthu sikudzatsimikiziridwa.Lero tikambirana za cholumikizira terminal "shelufu moyo".
Terminal "shelf life" imatanthawuza kuchokera pakupanga ndi kuyang'anira oyenerera kukhazikitsa makina asanafike nthawi yosungiramo zinthu zina zachilengedwe, ndipo nthawi yabwino yosungiramo malo osungiramo malo ndi nthawi yosungiramo khalidwe ndi kudalirika poika makina amatha kukwaniritsa zofunikira zapanthawiyo, nthawi yotsimikizika yoyambira siyimaganiziridwa kuti ndi gawo lapamwamba lanthawi yosungirako.
A, zinthu zomwe zimakhudza nthawi yosungiramo ma terminal.
Nthawi yosungira bwino ya kutalika kwa terminal ndi zinthu zitatu zotsatirazi zokhudzana ndi.
1. Ubwino wa terminal, ndikuwonetsetsa kuti terminal mu nthawi yosungirako bwino komanso yodalirika sikungawononge kwambiri zinthu zofunika;
2. Terminal yosungirako zinthu zachilengedwe.
3. Kusungirako ma terminal pambuyo pa ziyeneretso.
Zambiri mwazinthu zonse ndi tsatanetsatane wa ma terminal blocks amafotokozedwa m'malo osungiramo ma terminal blocks.
Monga SJ331 amapereka semiconductor Integrated dera yosungirako zinthu zachilengedwe: -10 ℃ ~ +40 ℃, RH ≤ 80%;US asilikali muyezo wa semiconductor Integrated dera yosungirako chilengedwe kutentha osiyanasiyana -65 ℃ ~ +150 ℃.GB4798.1 imapereka kusungirako zida mwatsatanetsatane, malo osungiramo zinthu zosungirako zachilengedwe pamlingo wapamwamba kwambiri, chilengedwe: 20 ℃ ~ 25 ℃;RH kwa 20% ~ 70%;Kuthamanga kwa mpweya kwa 70kPa ~ 106kPa.QJ2222A imapereka malo osungirako ndi malo apadera osungirako mitundu iwiri ya zinthu.
Chachiwiri, nthawi yabwino yosungiramo ma terminal blocks
The terminal amapangidwa ndi zigawo zikuluzikulu ziwiri za zipangizo zosiyanasiyana: pulasitiki zotchingira mbali, osiyana plating hardware.Kusungirako pulasitiki ndi zitsulo sikufanana, nthawi yosungiramo zinthu zonse iyenera kukhala yofulumira kwambiri yokalamba.Nthawi zambiri, moyo wa zida zotetezera zimakhala ndi zaka 3, koma chifukwa cha malo osungiramo osiyanasiyana, zimasiyana kwambiri.
Miyezo ya asitikali aku US pazoyambira zoyambilira za "backlog" yopitilira miyezi 12 ya zida za semiconductor discrete iyenera kuyang'aniridwanso ikaperekedwa, zomwe zitha kuganiziridwa kuti nthawi yabwino yosungira zida za semiconductor discrete ndi miyezi 12.Pambuyo pa kutulutsidwa kwamtunduwu kumapereka miyezi yopitilira 24 ya zida za semiconductor discrete, kutumiza kuyenera kuyambiranso;kutulutsidwa kwa mtundu watsopano kumapereka "zotsalira" za miyezi yopitilira 36 ya zida za semiconductor discrete, kutumiza kuyenera kuyang'aniridwanso.
Chachitatu, kuyang'ananso kwakutali kwa terminal block
Zoposa zaka 3 za malo osungiramo zinthu, musanakhazikitsidwe ayenera kuyesedwanso.Mayeso owunikiranso akuphatikiza: kuyesa mawonekedwe amagetsi, kuyang'ana kowoneka bwino komanso kuwunika kowononga (DPA).Gwiritsani ntchito kukulitsa nthawi 3 ~ 10 kapena maikulosikopu kuti muwonetsetse kuyendera kwa block block.Kuphulika kwa ma terminal kapena chipolopolo chifukwa cha zolakwika zakupha;dzimbiri kapena kuwonongeka kwa nthaka chifukwa cha zolakwika zazikulu;kuyanika pamwamba, matuza kapena chizindikiro chosawoneka bwino koma sichimakhudza kugwiritsa ntchito kuwonongeka kwa kuwala.Izi zolakwika zitatu za terminal block kwa osayenera.Mayeso amagetsi amagetsi, mawonekedwe amagetsi a ma terminal ayesedwa m'nyumba yosungiramo katundu, ayenera kuyesedwa molingana ndi njira ya magawo omwewo a mayeso.Kwa mawonekedwe amagetsi a terminal omwe sanayesedwe panthawi yosungidwa, kutengera mwatsatanetsatane mwatsatanetsatane wa terminal kapena ntchito yoyesa buku lazinthu ndi magawo akulu.
Mwachidule, "moyo wa alumali" wotsiriza ndi wautali kwambiri, koma nthawi yosungiramo bwino siitali, mu kutentha, kuwongolera chinyezi kuli bwino, moyo mpaka zaka 3, ngati chilengedwe chili choipa, moyo wotsiriza wa chimodzi chokha theka la zaka kapena ngakhale wamfupi, asidi ndi zamchere chilengedwe pa kuwonongeka terminal ndi lalikulu kwambiri, choncho tiyenera nthawi zonse mankhwala kuyezetsa, anapeza kukalamba chodabwitsa yomweyo m`malo cholumikizira terminal.
