Best Technology ndi mmodzi wa opanga bwino pcb ndi kusindikizidwa dera bolodi ogulitsa China
Kusintha kwa kutentha kwa ntchito kumatha kukhudza kwambiri magwiridwe antchito, kudalirika, moyo wonse komanso mtundu wazinthu. Kutentha kumakwera kumapangitsa kuti zinthu zikuchuluke, komabe, zinthu zam'munsi zomwe PCB imapangidwira zimakhala ndi ma coefficients osiyanasiyana owonjezera kutentha, izi zimayambitsa kupsinjika kwamakina komwe kungapangitse ming'alu yaying'ono yomwe ingakhale yosazindikirika pakuyesa kwamagetsi komwe kumachitika kumapeto kwa kupanga.
Chifukwa cha ndondomeko ya RoHS yomwe idatulutsidwa mu 2002 idafunikira ma aloyi opanda lead kuti asunthire. Komabe, kuchotsa chiwongolero mwachindunji kumabweretsa kukwera kwa kutentha kosungunuka, ma board ozungulira osindikizidwa amatengera kutentha kwambiri panthawi ya soldering (kuphatikizanso reflow ndi wave). Kutengera njira yosankhidwa yosinthira (imodzi, iwiri…), ndikofunikira kugwiritsa ntchito PCB yokhala ndi mawonekedwe oyenera amakina, makamaka yokhala ndi Tg yoyenera.
Tg ndi chiyani?
Tg (kutentha kwa kutentha kwa galasi) ndi mtengo wa kutentha womwe umatsimikizira kukhazikika kwa makina a PCB panthawi yogwira ntchito ya PCB, imatanthawuza kutentha kwakukulu komwe gawo lapansi limasungunuka kuchokera kumadzi olimba kupita kumadzi a rubberized, timatcha mfundo ya Tg, kapena malo osungunuka kuti amvetsetse mosavuta. Pamwamba pa mfundo ya Tg ndi, kutentha kwapamwamba kwa bolodi kudzakhala pamene laminated, ndipo Tg board yapamwamba pambuyo pa laminated idzakhalanso yolimba komanso yowonongeka, yomwe imapindula ndi ndondomeko yotsatira monga kubowola makina (ngati ilipo) ndikusunga magetsi abwino pakugwiritsa ntchito.
Kutentha kwa kusintha kwa galasi ndikovuta kuyeza molondola poganizira zinthu zambiri, komanso chinthu chilichonse chimakhala ndi mawonekedwe akeake, chifukwa chake, zida zosiyanasiyana zimakhala ndi kutentha kosiyana kwa galasi, ndipo zida ziwiri zosiyana zimatha kukhala ndi mtengo wofanana wa Tg ngakhale ali ndi mawonekedwe osiyanasiyana, izi zimatithandiza kukhala ndi chisankho china pamene zinthu zomwe zimafunikira sizitha.
Zinthu za High Tg
l Kukhazikika bwino kwamafuta
l Good kukana chinyezi
l Kuchepetsa kutentha kwachulukidwe kagawo
l Kukana kwamankhwala kwabwino kuposa zinthu zochepa za Tg
l Mtengo wapamwamba wa kukana kupsinjika kwamafuta
l Kudalirika kwambiri
Ubwino wa High Tg PCB
Nthawi zambiri, PCB FR4-Tg yabwinobwino ndi madigiri 130-140, sing'anga Tg ndi yayikulu kuposa madigiri 150-160, ndipo Tg yayikulu ndi yayikulu kuposa madigiri 170, High FR4-Tg idzakhala yabwino kukana kutentha kwamakina ndi chinyezi kuposa FR4 wamba, nazi zina zabwino za Tg PCB yapamwamba kuti muwunikenso:
1. Kukhazikika kwapamwamba: Zimangowonjezera kukana kutentha, kukana kwa mankhwala, kukana chinyezi, komanso kukhazikika kwa chipangizocho ngati kukulitsa Tg ya gawo lapansi la PCB.
2. Kupirira kachulukidwe kachulukidwe kamphamvu: Ngati chipangizocho chili ndi kachulukidwe kakang'ono kwambiri komanso calorie yotsika kwambiri, ndiye kuti Tg PCB yapamwamba idzakhala yankho labwino pakuwongolera kutentha.
3. Ma board okulirapo osindikizidwa atha kugwiritsidwa ntchito kusintha kapangidwe kake ndi zofunikira za mphamvu za zida ndikuchepetsa kutentha kwa matabwa wamba, komanso Tg PCBS yayikulu ingagwiritsidwenso ntchito.
4. Kusankha koyenera kwa ma multilayer ndi HDI PCB: Chifukwa ma multi-layer ndi HDI PCB ndi ophatikizana komanso ozungulira, zimabweretsa kutentha kwakukulu. Chifukwa chake, ma PCB apamwamba a TG amagwiritsidwa ntchito mumitundu yambiri komanso ma PCB a HDI kuti atsimikizire kudalirika kwa kupanga kwa PCB.
Kodi ndi liti pamene mukufuna High Tg PCB?
Nthawi zambiri kuti PCB igwire bwino ntchito, kutentha kwambiri kwa board board kuyenera kukhala pafupifupi madigiri 20 kuposa kutentha kwa magalasi. Mwachitsanzo, ngati mtengo wa Tg wa zinthu ndi madigiri 150, ndiye kuti kutentha kwenikweni kwa bolodi lozungulira sikuyenera kupitirira madigiri 130. Ndiye, ndi liti pamene mukufuna Tg PCB yapamwamba?
1. Ngati ntchito yanu yomaliza ikufunika kunyamula katundu wotentha kwambiri kuposa madigiri 25 centigrade pansi pa Tg, ndiye kuti Tg PCB yapamwamba ndiye chisankho chabwino kwambiri pazosowa zanu.
2. Kuti muwonetsetse chitetezo zinthu zanu zikafuna kutentha kofanana kapena kupitilira madigiri 130, Tg PCB yapamwamba ndiyabwino kugwiritsa ntchito.
3. Ngati pulogalamu yanu ikufuna PCB yamitundu ingapo kuti ikwaniritse zosowa zanu, ndiye kuti Tg yapamwamba ndiyabwino kwa PCB.
Mapulogalamu omwe amafunikira Tg PCB yapamwamba
l Chipata
l Inverter
l Mlongoti
l Wifi Booster
l Embedded Systems Development
l Mapulogalamu apakompyuta ophatikizidwa
l Ac Power Supplies
l RF chipangizo
l Makampani a LED
Best Tech ili ndi luso lopanga High Tg PCB, titha kupanga ma PCB kuchokera ku Tg170 kupita ku Tg260 yapamwamba, pakadali pano, ngati pulogalamu yanu ikufunika kutentha kwambiri ngati 800C, mungagwiritse ntchito bwino.Ceramic board zomwe zimatha kudutsa -55 ~ 880C.
