Kuongorora PCB Board Zvishandiso

ziviso

Nyika yemabhodhi edunhu akadhindwa (PCBs) yakaoma uye iri kuchinja. Sezvo kudiwa kwemaPCB kuri kuramba kuchiwedzera, kusarudza zvinhu zvePCB board zvakakodzera kwave chinhu chakakosha kune mainjiniya nevagadziri. Muhurukuro iyi yakakura, tichaongorora pfungwa, kupatsanura, uye zvinhu zvakasiyana-siyana zvinoshandiswa mukugadzira maPCB . Pamusoro pezvo, tichaongorora zvakanyanya nzvimbo chaiyo yemaPCB eHigh Tg (Glass Transition Temperature), tichiongorora kukosha kwawo, mabhenefiti, zvirevo, mashandisirwo, uye zvikonzero zvekushandiswa kwawo.

Pfungwa yePCB Board Zvishandiso

Mabhodhi ePCB, anowanzo kunzi substrates, anoshanda sechinhu chakakosha pakavakirwa masekete emagetsi. Aya mapuranga anowanzo kuumbwa neCopper Clad Laminate (CCL), iyo inogadzirwa nekumisikidza mapuranga pulp bepa kana girazi fiber jira rine resin uye nekufukidza rimwe kana mativi ese nemhangura foil. CCL inomira sedombo repakona reindasitiri yemagetsi, inonyanya kushandiswa kugadzira akadhindwa edunhu mabhodhi (PCBs) anowana mashandisirwo awo mumhando dzakasiyana dzezvigadzirwa zvemagetsi, zvinosanganisira terevhizheni, maredhiyo, makomputa, nharembozha, nemidziyo yekutaurirana.

Kurongwa kwePCB Board Materials

Zvishandiso zvePCB bhodhi zvakaiswa muzvikamu zvichibva pane zvakasiyana siyana seTg (Glass Transition Temperature), giredhi level, uye zvekusimbisa zvinhu.

Tg (Girazi Rekuchinja Tembiricha): Tg chinhu chakakosha pakusarudza zvinhu zvePCB. Izvi zvinoratidza tembiricha iyo polymer inochinja kubva pakuva yakaoma kuita segirazi kuenda kune inonamira zvakanyanya. Mainjiniya anowanzo koshesa Tg values, kunyanya kana tichitarisa magirazi e-fiber-based copper clad laminates akadai seFR-4. Mienzaniso yeTg values ​​inosanganisira tg140°C, tg160°C, uye tg180°C. Zvinhu zvepamusoro zveTg zvinofarirwa nekuda kwemagadzirirwo akavimbika zvakanyanya nekuda kwekuwedzera kwekudzivirira kupisa, zvichiita kuti Tg ive chiratidzo chekudzivirira kupisa kwebhodhi panguva yekubatanidza lead.

Kupatsanurwa Kwegiredhi: Zvinhu zvebhodhi rePCB zvakakamurwa kuita mamakisi akasiyana, kubva pakaderera kusvika pakakwirira:

• FR-4a1: Inonyanya kushandiswa mumauto, kutaurirana, makomputa, maseketi edhijitari, zviridzwa zveindasitiri, uye mota dzemagetsi.
• FR-4a2: Inokodzera makomputa emazuva ese, zviridzwa, midziyo yemumba yepamusoro, uye zvigadzirwa zvemagetsi zvakajairika.
• FR-4a3: Yakagadzirirwa zvakanyanya indasitiri yemidziyo yemumba, macomputer epamhepo, uye zvakajairika zvigadzirwa zvemagetsi. Inopa kukwikwidza mitengo paunenge uchisangana nekuita zvinodiwa.
• FR-4ab Giredhi: Inomiririra yakasarudzika, yakaderera-giredhi sarudzo ine maitiro metrics ayo achiri kuenderana neyakajairwa midziyo yemumba, makomputa, uye zvakajairika zvigadzirwa zvemagetsi. Inopa kukwikwidza kwakanyanya mitengo uye yakanakisa kuita-mutengo reshiyo.
• FR-4b Giredhi: Inoratidzwa nemhando yakaderera uye yakashata kunaka kugadzikana. Hazvikurudzirwe kumabhodhi ematunhu makuru uye anowanzo shandiswa kune zvigadzirwa zvidiki (semuenzaniso, 100mmx200mm). Inopa mutengo wakaderera asi inoda kunyatsotariswa.
• CEM-3 Series: Inowanikwa muchena, nhema, uye mavara echisikigo, anonyanya kushandiswa mumakomputa, maindasitiri e LED, wachi, midziyo yemumba, uye zvigadzirwa zvemagetsi zvakajairika seVCD, maDVD, matoyi, uye michina yemitambo. Inozivikanwa nekunakisa punching performance, yakakodzera kune yakakwira-vhoriyamu PCB zvigadzirwa zvinoda kutsika maitiro. Inopa mazinga matatu emhando: A1, A2, uye A3.

Zvinhu Zvinosimbisa: Zvinhu zvebhodhi rePCB zvinopatsanurwawo zvichienderana nezvinhu zvinoshandiswa kusimbisa:

• Phenolic PCB Pepa Substrate: Inoumbwa nehuni pulp fiber bepa rakaiswa ne phenolic resin. Mhando zvinosanganisira XPC, FR-1, FR-2, Fe-3, uye 94V0 inodzoreredza murazvo.
• Composite PCB Substrate: Yakagadzirwa nehuni pulp fiber bepa kana donje pulp fiber bepa sechinhu chekusimbisa, negirazi fiber jira sekusimbisa pamusoro. Kazhinji inoshandisa murazvo-retardant epoxy resin. Inosanganisira imwechete-sided semi-girazi fiber 22F, CEM-1 uye kaviri-sided semi-girazi fiber CEM-3.
• Fiberglass PCB Substrate: Inoshandisa epoxy resin seanonamira uye girazi fiber jira sechinhu chekusimbisa. Inozivikanwa nekupisa kwekushanda kwakanyanya uye kushomeka kwemamiriro ekunze. Inowanzo shandiswa mumaviri-mativi PCBs, makomputa, peripherals, uye midziyo yekutaurirana.

Yakakwira Tg PCBs - Kukosha uye Mabhenefiti

Tsanangudzo yeHigh Tg PCB: High Tg PCBs ndeaya ane tembiricha yepamusoro yekuchinja kwegirazi, zvichireva nzvimbo iyo zvinhu zvepasi (polymer kana girazi) zvinoshanduka kubva pachimiro chakasimba, chegirazi kuenda pachimiro chinochinjika, cherabha. Kuchinja uku kwakakosha, sezvo kunosarudza kuramba kupisa kwechinhu ichi, zvichiita kuti chirambe chakasimba pakupisa kwakakwirira. High Tg PCBs inonyanya kukosha munzvimbo umo maPCB akajairwa anogona kupfava, kuchinja chimiro, kana kuona kudzikira kukuru kwehunhu hwemakanika nemagetsi.

Mabhenefiti eHigh Tg PCB: High Tg PCBs inopa mabhenefiti akati wandei:

• Higher Stability: Yakakwirira Tg zvinhu zvinongo wedzera kupisa kuramba, makemikari kuramba, hunyoro kuramba, uye kugadzikana kwese kwemidziyo, zvichibatsira mukuvandudza kuvimbika.
• Inokodzera High Power Density Dhizaini: Yakakwirira Tg PCBs inokunda mukugadzirisa kupisa kunogadzirwa ne-high-simba-density madivayiri, zvichiita kuti ive yakanakira maapplication ane akakosha ekugadzira kupisa.
• Yakanakira Multilayer & HDI PCBs: Multilayer uye High-Density Interconnect (HDI) PCBs dzinowanzoda yakakwirira Tg zvinhu nekuda kwekubatana kwavo uye dense redunhu, kuve nechokwadi chekuvimbika panguva yekugadzira.

Magadzirirwo eHigh Tg PCB: Chinonyanya kukosha cheHigh Tg PCBs igirazi rekuchinja tembiricha (Tg). MaPCB akajairwa anowanzo kupa Tg kukosha kwe140°C, yakakodzera tembiricha yekushanda inosvika 110°C. Zvisinei, pamashandisirwo ekupisa kwakanyanya anowanzoitwa mumotokari, mumaindasitiri, kana mumagetsi anodziya zvakanyanya, High Tg PCBs, anowanzogadzirwa nezvinhu zveFR-4, ndiyo sarudzo inosarudzwa.

Mashandisirwo eHigh Tg PCB: High Tg PCBs dzinowana mashandisirwo munzvimbo dzakasiyana-siyana, dzinosanganisira:

• CAF - Conductive Anodic Filament: Inoshandiswa kudzivirira zvisingadiwe kuita filaments mu substrate yedunhu bhodhi.
• Multilayer Boards: Kunyanya kune madhizaini ane akawanda layers.
• Industrial Electronics: Inokodzera maindasitiri-giredhi emagetsi emidziyo.
• Automobile Electronics: Resilient munzvimbo dzekupisa kwepamusoro.
• Fine Line Trace Structures: Yakanakira kuomesesa uye compact dhizaini.
• High-Temperature Electronics: Yakakosha kune zvemagetsi zvinoshanda munzvimbo dzakakwirira tembiricha.

Sei Kusarudza Yakakwira Tg PCB?

Kusarudzwa kwemaHigh Tg PCB kunokonzerwa neindasitiri yemagetsi iri kuchinja, kunyanya munyaya dzemakomputa ane mashandiro epamusoro uye zvinodiwa zve multilayer. Pamusoro pezvo, kuvandudzwa kweSurface Mount Technology (SMT) neChip-on-Board Technology (CMT) nePCB assembly ine huwandu hwakanyanya hwema PCB kunoda zvinhu zvine simba rekudzivirira kupisa. Zvinhu zvine simba reTg zvinovandudza zvakanyanya simba rekudzivirira kupisa, simba rekudzivirira hunyoro, simba rekudzivirira makemikari, uye kugadzikana kwese, zvichiita kuti zvive zvakakosha mukugadzira maPCB asina lead.

Nguva Yekusarudza Yepamusoro Tg PCBs

High Tg PCBs inodarika vamwe vawo vakajairwa, kunyanya munzvimbo inopisa uye ine mwando, inokunda musimba remagetsi, kugadzikana kwedimensional, kunamatira, kunyura kwemvura, uye kuora kwekupisa. Vagadziri vanowanzo sarudza High Tg zvinhu zve-high-layer PCBs (kunyanya ≥10 layers) kana akawanda-layer inorema mhangura PCBs (≥3oz) kuve nechokwadi chakawedzera kuvimbika uye kunaka. Zvinowanzoshandiswa High Tg zvinhu zvinosanganisira ITEQ IT180, Shengyi S1000-2, uye EMC EM827. Nepo zvinhu zvine Tg zvakakosha zvinodarika 190 ° C kana 210 ° C zvisingawanzo, zviripo, zvine sarudzo senge Isola FR408HR, inonyanya kushandiswa mumashandisirwo epamusoro-soro, kunyangwe nemutengo wepamusoro pane zvakajairwa zvinhu.

Kazhinji, kunzwisisa zvinhu zvePCB board, kupatsanurwa kwadzo, uye kukosha kweHigh Tg PCBs kwakakosha kune mainjiniya nevagadziri. Kusarudzwa kwezvinhu zvePCB kunoita basa guru mukuona kuvimbika, kushanda, uye kushanda kwezvigadzirwa zvemagetsi mumaindasitiri akasiyana-siyana. Nekushanduka kwetekinoroji nekukurumidza, kugara uchiziva nezvekufambira mberi kwezvinhu kwakakosha kuti urambe uri pamberi mukugadzirwa kwePCB.

Kana chirongwa ichi chachinja kubva pakutsvagisa kuenda kuRFQ, ongorora kuongororwa kwePCB nekudzora mhando uye rutsigiro rwekugadzira zvemagetsi kuitira kuti zvinodiwa pakugadzira, maitiro, uye kuongorora zvirambe zvakaenzana.
