Best Technology ndeimwe yakanakisisa pcb vagadziri uye akadhindwa redunhu bhodhi vatengesi mu China
Kuchinja kwekushisa kwekushanda kunogona kuva nesimba guru pakushanda, kuvimbika, hupenyu hwose uye kunaka kwezvigadzirwa. Tembiricha inokwira inokonzeresa kuti zvinhu zviwedzere, zvisinei, iyo substrate zvinhu izvo PCB inogadzirwa ine akasiyana ekuwedzera ekupisa coefficients, izvi zvinokonzeresa kushushikana kwemagetsi kunogona kugadzira madiki-akatsemuka anogona kusaonekwa panguva yekuyedzwa kwemagetsi kunoitwa pakupera kwekugadzirwa.
Nekuda kwemutemo weRoHS wakapihwa muna 2002 waida lead-isina ma alloys ekutengesa. Nekudaro, kubvisa lead yakananga kunokonzeresa kukwira kwekushisa kwekunyunguduka, mabhodhi edunhu akadhindwa saka ari pasi pekushisa kwepamusoro panguva yekutengesa (kusanganisira reflow uye wave). Zvichienderana neakasarudzwa reflow process (imwechete, yakapetwa kaviri…), zvinodikanwa kushandisa PCB ine hunhu hwakakodzera hwemuchina, kunyanya ine Tg yakakodzera.
Chii chinonzi Tg?
Tg (tembiricha yegirazi) ndiyo kukosha kwetembiricha inovimbisa kugadzikana kwePCB panguva yekushanda kwehupenyu hwePCB, inoreva tembiricha yakaoma iyo iyo substrate inonyungudika kubva pakasimba kuenda kumvura ine rubberized, isu takadaidza kuti Tg point, kana nzvimbo yekunyungudika kuti zvive nyore kunzwisisa. Iyo yakakwirira iyo Tg point ndeye, iyo yakakwirira tembiricha inodiwa yebhodhi ichave kana laminated, uye yakakwira Tg bhodhi mushure me laminated ichave yakaoma uye brittle, iyo inobatsira kune inotevera nzira senge mechanical drilling (kana iripo) uye chengetedza zviri nani magetsi emagetsi panguva yekushandisa.
Iyo tembiricha yekuchinja yegirazi yakaoma kuyerwa nemazvo mukufunga zvakawanda zvezvinhu, pamwe nechinhu chimwe nechimwe chine chimiro chayo chemorekuru, saka, zvinhu zvakasiyana zvine tembiricha yegirazi yakasiyana, uye zvinhu zviviri zvakasiyana zvinogona kuve neukoshi hwakafanana hweTg kunyangwe vaine hunhu hwakasiyana, izvi zvinoita kuti tive neimwe sarudzo kana chinhu chinodiwa chapera.
Zvimiro zveHigh Tg zvinhu
l Zvirinani kugadzikana kwekupisa
l Kuramba kwakanaka kune unyoro
l Lower thermal kuwedzera coefficient
l Yakanaka makemikari kuramba pane yakaderera Tg zvinhu
l Kukosha kwepamusoro kwekupisa kudzvinyirira kusagadzikana
l Excellent kuvimbika
Zvakanakira High Tg PCB
Kazhinji, yakajairika PCB FR4-Tg ndeye 130-140 madhigirii, iyo yepakati Tg yakakura kupfuura 150-160 madhigirii, uye yakakwira Tg yakakura kupfuura 170 madhigirii, Yakakwira FR4-Tg ichave nemagetsi uye makemikari kuramba kupisa uye kunyorova kupfuura yakajairwa FR4, heano mamwe mabhenefiti epamusoro Tg PCB pakuongorora kwako:
1. Kudzikama kwepamusoro: Iyo inongovandudza kupisa kwekudzivirira, makemikari kuramba, hunyoro kuramba, pamwe nekugadzikana kwechigadzirwa kana ichiwedzera Tg yePCB substrate.
2. Kushingirira dhizaini yemagetsi yakakwira: Kana chishandiso chine simba rakanyanya density uye yakaringana yakakwira calorific kukosha, ipapo yakakwira Tg PCB ichave mhinduro yakanaka yekutonga kupisa.
3. Makuru akadhindwa edunhu mabhodhi anogona kushandiswa kushandura dhizaini uye simba rinodiwa zvemidziyo uku ichidzikisa kupisa kugadzirwa kwemabhodhi akajairwa, uye yakakwirira Tg PCBS inogona zvakare kushandiswa.
4. Ideal sarudzo yeakawanda-layer uye HDI PCB: Nekuti akawanda-layer uye HDI PCB akanyanya compact uye redunhu dense, zvinoguma nehupamhi hwekupisa kupisa. Naizvozvo, yakakwirira TG PCBs anowanzo shandiswa mune akawanda-layer uye HDI PCBs kuve nechokwadi chekuvimbika kwePCB kugadzira.
Ndepapi paunoda High Tg PCB?
Kazhinji kuti uve nechokwadi chekushanda kwakanakisa kwePCB, iyo tembiricha yekushanda yebhodhi redunhu inofanira kunge iri madhigirii makumi maviri pane tembiricha yegirazi. Semuenzaniso, kana kukosha kweTg kwezvinhu kuri 150 degrees, saka tembiricha chaiyo yekushanda yebhodhi redunhu haifanire kudarika 130 degrees. Saka, iwe unoda riini yakakwira Tg PCB?
1. Kana yako yekupedzisira application ichida kutakura mutoro wekupisa wakakura kupfuura 25 degrees centigrade pazasi peTg, saka yakakwira Tg PCB ndiyo yakanakisa sarudzo kune zvaunoda.
2. Kuve nechokwadi chekuchengetedza kana zvigadzirwa zvako zvichida tembiricha yekushandisa yakaenzana kana yakakura kupfuura 130 madhigirii, yakakwira Tg PCB yakanakira application yako.
3. Kana application yako ichida akawanda-layer PCB kuti isangane nezvido zvako, saka yakakwira Tg zvinhu yakanakira PCB.
