Zvinhu zvePCB Zvisina Musoro zveKuungana kwePCB uye Kugadzirwa kwePCBA Kwakavimbika

Kusarudzwa kwezvinhu zvePCB zvisina mutobvu kunofanira kukurukurwa muhurukuro yekubatanidza, kwete chete mumashoko ebhodhi risina chinhu. Mubvunzo unoshanda ndewekuti laminate, surface finish, solder mask, package mix, uye reflow process zvinogona here kutsigira kuvaka kwakasimba kusina mutobvu pasina kukonzera warpage, wetting, kana matambudziko ekuongorora gare gare mukugadzirwa.

Highleap Electronics inoongorora mabhodhi asina lead semapurojekiti akakwana ePCBA. Isu tinobatanidza sarudzo ye laminate nePCB isina lead , solder isina lead , dhizaini yestencil, SMT assembly, uye coverage yekuongorora kuitira kuti bhodhi rigone kufamba zvakanaka kubva pakugadzirwa kuenda pakugadziriswa kunodzokororwa.

Zvinoreva Kusarudzwa Kwezvinhu Zvisina Mutobvu

Chinangwa ndechekuva nechokwadi chekubatanidza, kwete chiratidzo chiri pamufananidzo

Mifananidzo yakawanda inotaura nezvekuenderana kusina mutobvu pasina kujekesa dambudziko rinofanira kugadziriswa. Muchokwadi, ongororo yezvinhu ndeye kana bhodhi richigona kurarama tembiricha yakakwira yekuyerera, kuchengetedza rakati sandara, kutsigira kupedzisa kwenzvimbo yakasarudzwa, uye kupasa bvunzo mushure mekuungana.

Izvi zvinoreva kuti hurukuro ye laminate inofanira kubatanidzwa kune seti chaiyo yezvikamu uye nzira yekugadzirisa. Bhodhi rakavakwa nezvikamu zvidiki zvisingashande uye SMT iri nyore ringasada sarudzo yakafanana neyekuungana kweBGA yakakora kana bhodhi rekudzora reindasitiri rine layer yakawanda.

Zvinodiwa zvekushandisa pasina mutobvu zvinowanzobva panzvimbo yekuungana

Zviratidzo zvakasimba zvinowanzova zvinoshanda: kudzokororwa kwekubuda kwedata, kukanganiswa nemapakeji, kunetseka nezve warpage, kana kutarisira kutevedzera mitemo yekutumira kunze kwenyika. Saka Highleap inosarudza kuongorora kusarudzwa kwezvinhu pamwe chete nemafaira ekuunganidza kwete senyaya isina chinhu.

Kuchinja Kwakaita Kushushikana Kwekudzokera Mukati Kusarudzo yePCB

Kudzokorora kweprofile kunogona kuratidza kushaya simba kusingaonekwe mukugadzirwa chete

Kuungana kusina mutobvu kunowanzoita kuti tembiricha yepamusoro iwedzere kupfuura kusungirirwa kwetin-lead, izvo zvinogona kuwedzera kushushikana pa laminate, maburi akaiswa plated, mask yekusolder, nenzvimbo dzakakura dzepakeji. Kana bhodhi rakatetepa, risina kuenzana zvakanaka, kana kuti rakazadzwa nekupisa kukuru, kushushikana ikoko kunonyanya kukosha.

• Laminate kupisa kutsungirira uye divi kugadzikana
• Ukobvu hwebhodhi uye chiyero chemhangura
• Nhamba inotarisirwa yekudzoka kwemafambiro emvura uye chero kuratidzwa kwekugadzirisazve
• Zvikamu zvikuru kana nzvimbo dzinopisa zvinochinja maitiro ekupisa kwenzvimbo

Nechikonzero ichi, ongororo yebhodhi isina lead inofanira kusanganisira fungidziro dzemaitiro, kwete kungoti mutemo unotevedzera mitemo chete. Pazvinenge zvichidikanwa, Highleap inoenzanisa kurudziro neHigh Tg FR4 PCB yekugadzira kana dzimwe nzira dzezvinhu dzinotsigira zviri nani mutoro wekupisa.

Kusatsetseka kwebhodhi kunokanganisa goho nguva refu munda usati watanga kukundikana

Magungano ane zvikamu zvakapfava, maBGA, kana maconnector makuru anogona kurasikirwa negoho kana bhodhi rikanyanya kufamba panguva yekupisa. Mukuvaka ikoko, kusarudzwa kwezvinhu uye chimiro chebhodhi zvinofanirwa kutariswa sesarudzo dzegoho rekugadzira, kwete ruzivo rwekugadzira chete.

Sarudzo dzeKupedzisa Pamusoro peKuungana Kusina Lead

Kupedzisa kunofanirwa kuenderana nemusanganiswa wepakeji uye hurongwa hwekuchengetera

Kushanda kwesolder isina mutobvu kunoenderana zvakanyanya nekugadzirwa kwechinhu chakasarudzwa. ENIG, ENEPIG, OSP, sirivha yekunyudza, tin yekunyudza, uye HASL isina mutobvu zvinogadzira kusiyana kwakasiyana mukusatsetseka, hupenyu hwekuchengetedza, mutengo, uye kugara kwakabatana.

Highleap inosimbisa kupera kwayo zvichienderana nemusanganiswa wepakeji uye tarisiro yekuchengetedza kana kutumira isati yapedzisa nzira yekuunganidza.

Kusanganiswa kwePakeji, MSL, uye Kuronga Kuongorora

Kunzwa kwezvikamu kunowanzo tsanangura hwindo rekuchengetedza maitiro

Kushanda kwebhodhi kusina mutobvu kunoenderana neBOM sezvinoita bhodhi. Midziyo inonzwa hunyoro, ma "thermal pads" makuru, ma "BGAs", ma "QFNs", ma "press-fit connectors", uye ma "mixed through-hole assemblies" zvese zvinoshandura mavakirwo uye kuongororwa kwebhodhi.

Highleap inoongorora mashandiro eMSL, zvinodiwa pakubika, nzira yekunyora stencil, X-ray coverage, uye chero tarisiro yekuedza kushanda kwayo isati yaburitsa hurongwa hwekugadzira. Mapurojekiti akafanana anowanzoenderana nemabasa ekugadzira PCB uye kuvaka kwakasimba uko kurangwa kwemaitiro kunonyanya kukosha kupfuura mutengo webhodhi risina kugadzirwa.

Chiyero chekuongorora chinofanira kuenderana nenjodzi chaiyo yekuungana

Kuyerera kweAOI chete kunogona kukwana kune mamwe mabhodhi eSMT, asi chivakwa chakasimba chisina mutobvu chine maBGA kana majoini akavanzwa chinogona kuda X-ray kana kuongororwa kwakawedzerwa. Pakeji yekuongorora yakakodzera inofanira kuiswa pamberi pemutengo, kwete kuwedzerwa mushure mekunge mutsetse watorongwa.

Kunoda Kugadziriswa Kwekugadzira Nekusanganisa

Zvinyorwa zvekugadzira zvinofanirwa kutsigira maitiro ekugadzira

Mabhodhi asina mutobvu anoshanda zviri nani kana mapedhi ekugadzirisa, kutsanangurwa kwemamasiki ekusolder, copper balance, uye nzira dzepaneru zvichisarudzwa tichifunga nezvekubatanidza. Kana mafaira ebhodhi risina chinhu uye mafaira ekubatanidza akagadzirwa ega, Highleap inotarisa kuti haana kuenderana here isati yaburitswa.

Izvi zvinonyanya kukosha pamabhodhi ane nzira yekubuda nayo yeBGA, nzvimbo yakabatana, mapuraneti makuru emhangura, kana SMT yakasanganiswa uye zvinhu zviri mukati megomba. Muzviitiko izvozvo, kusarudza zvinhu, kusarudza kwekupedzisa, uye kuronga kuongorora zvinofanirwa kufamba pamwe chete pane kutaurirana kwakasiyana kwekupedzisira.

Kudzokorora kugadzirwa kunoda hwindo remaitiro rakakiyiwa

Kana mubatanidzwa usina mutobvu wasimbiswa, zvinhu, magumo, mhuri yekunamira, uye fungidziro dzekuongorora dzinofanira kuendeswa mberi zvakajeka. Zvikasadaro, odha inotevera inogona kuvhurazve mibvunzo inodzivisika uye kugadzira shanduko apo kuvaka kwekutanga kwaive kwakagadzikana.

Zvinodiwa neHighleap kuti uwane Quote yePCBA Isina Lead

Pakeji yakazara inobvumira mhinduro chaiyo yemusangano

• Gerber kana ODB++, ruzivo rwekudhirowa, uye zvinyorwa zvekugadzira
• BOM, pick-and-place, uye gungano draw
• Kupedzwa kwepamusoro uye chero zvinodiwa zvemidziyo zvakatenderwa
• MSL kana manotsi ekubata zvinhu zvinonzwa
• Kuongororwa kwenzvimbo dzakadai seAOI, X-ray, kana bvunzo inoshanda
• Huwandu hwakatarwa, nguva yekutungamirira, uye zvinotarisirwa kuti zvitevedzwe

Ruzivo irworwo runoita kuti Highleap iongorore bhodhi risina lead sechirongwa chePCBA chaicho kwete seti yemagwaro asina kukwana.

FAQs

Ko chivakwa chega chega chisina mutobvu chinoda zvinhu zveHigh Tg here?

Kwete. Zvinoenderana nechimiro chebhodhi, musanganiswa wepakeji, uye kuratidzwa kwemaitiro acho. Mamwe ma assemblies anoshanda zvakanaka pazvinhu zvakajairwa, nepo mamwe achibatsirwa nekuvandudzwa kwekupisa.

Ko ENIG ndiyo nguva dzose yakanakisisa yekupedzisa kuunganidza pasina mutobvu here?

Kwete nguva dzose. Isarudzo yakanaka kune akawanda magadzirirwo esimbi, asi kupedzisa kwakanaka kunoenderana nekuti yakatsetseka sei, mutengo, nguva yekushanda, uye musanganiswa wezvikamu.

Highleap inogona here kuongorora bhodhi risina chinhu pamwe chete nepakeji yekubatanidza?

Ehe. Ndiyo nzira yakanakisa yekudzivirira kurasikirwa negoho kunokonzerwa nekusawirirana pakati pekufungidzira kwekugadzira nemaitiro chaiwo ekugadzira.
