Our Process
1. Kunyudza goridhe maitiro: Chinangwa chekunyudza goridhe process ndeyekuisa nickel-goridhe coating ine yakagadzikana ruvara, kupenya kwakanaka, yakapfava yakapfava uye yakanaka solderability pamusoro pePCB, iyo inogona kukamurwa kuita nhanho ina: pretreatment. (Degreasing, micro-etching, activation, post-dipping), kunyudza nickel, kunyudza goridhe, post-kurapwa, (kurasa goridhe kugeza, DI kugeza, kuomesa).
2. Lead-sprayed tin: Tembiricha ine lead-ine eutectic tembiricha yakaderera pane yearoyi isina mutobvu.Iyo chaiyo mari inoenderana nekuumbwa kweiyo lead-isina alloy.Semuenzaniso, iyo eutectic yeSNAGCU ndeye 217 madhigirii.Iyo tembiricha yekudziya ndiyo tembiricha ye eutectic pamwe ne30-50 madhigirii, zvichienderana nekuumbwa.Kugadzirisa chaiko, iyo inotungamira eutectic ndeye 183 madhigirii.Mechanical simba, kupenya, etc. lead zviri nani pane lead-isina.
3. Kupfapfaidza tin-isina lead: Mutobvu unovandudza kuita kwewaya yerata mukuita kwewelding.Waya yemutobvu iri nyore kushandisa pane waya isina mutobvu, asi mutobvu une chepfu, uye hauna kunaka kumuviri wemunhu kana ukashandiswa kwenguva yakareba.Uye tini risina mutobvu rinenge riine kunyungudika kwakakwirira kudarika lead-tin, kuitira kuti majoini anotengeswa ave akasimba zvikuru.
Iyo chaiyo maitiro ePCB maviri-mativi edunhu redunhu bhodhi kugadzira maitiro
1. CNC kuchera
Kuti uwedzere kuwanda kwegungano, maburi ari pamativi maviri edunhu redunhu rePCB ari kuita madiki nekudiki.Kazhinji, mativi maviri-mativi pcb mabhodhi anocherwa neCNC yekuchera michina kuti ive nechokwadi chechokwadi.
2. Electroplating hole process
The plated buri muitiro, anonziwo metallized gomba, inzira iyo yose buri madziro akaputirwa nesimbi kuitira kuti conductive mapatani pakati yomukati uye kunze akaturikidzana kaviri-mativi akadhindwa redunhu bhodhi anogona magetsi interconnected.
3. Screen kudhinda
Zvishandiso zvakakosha zvekudhinda zvinoshandiswa kudhinda sikirini edunhu mapatani, solder mask mapatani, mavara emhando mapatani, nezvimwe.
4. Electroplating tin-lead alloy
Electroplating tin-lead alloys ine mabasa maviri: kutanga, se anti-corrosion protective layer panguva ye electroplating uye etching;chechipiri, sechifukidziro chinotengeswa chebhodhi rakapedzwa.Electroplating tin-lead alloys inofanira kunyatso kudzora bhati uye maitiro ekugadzirisa.Ukobvu hwe-tin-lead alloy plating layer inofanira kunge inopfuura 8 microns, uye gomba remadziro harifanirwe kunge riri pasi pe2.5 microns.
bhodhi redunhu rakadhindwa
5. Etching
Paunenge uchishandisa tin-lead alloy sechidziviriro chekudzivirira kugadzira kaviri-mativi mapaneru ne patterned electroplating etching method, ane acid copper chloride etching solution uye ferric chloride etching solution haigone kushandiswa nokuti inoparadzawo tin-lead alloy.Mukuita etching, "side etching" uye kukwirisa coating zvinhu zvinokanganisa etching: mhando
(1) Kuora kweparutivi.Side corrosion chiitiko chekunyura kana kunyura kwema conductor edges kunokonzerwa ne etching.Kukura kwekuora kweparutivi kune hukama nekugadzirisa mhinduro, zvishandiso uye mamiriro ekugadzirisa.Izvo zvishoma flank corrosion zviri nani.
(2) Kuputira kunowedzerwa.Kuwedzera kwekuputira kunokonzerwa nekuwedzerwa kwekuputira, izvo zvinoita kuti hupamhi hweimwe rutivi rwetambo kudarika hupamhi hweplate yepasi yakapedzwa.
6. Kuisa goridhe
Goridhe plating ine yakanakisa conductivity yemagetsi, diki uye yakagadzikana yekubata kuramba uye yakanakisa kupfeka kuramba, uye ndiyo yakanakisa plating zvinhu zveakadhindwa redunhu bhodhi plugs.Panguva imwecheteyo, ine yakanakisa kugadzikana kwekemikari uye solderability, uye inogona zvakare kushandiswa seyakaonda-resistant, solderable uye inodzivirira coating pamusoro pegomo PCBs.
7. Kupisa kunyunguduka uye kupisa kwemhepo kuenzana
(1) Kunyungudika kunopisa.Iyo pcb yakavharwa neSn-Pb alloy inopisa kusvika pamusoro pekunyunguduka kweSn-Pb alloy, kuitira kuti Sn-Pb neCu vagadzire simbi yesimbi, kuitira kuti iyo Sn-Pb yekupfekedza ine dense, yakajeka uye isina pinho, uye iyo corrosion resistance uye solderability yejasi inovandudzwa.sex.Kupisa-kunyunguduka kunowanzo shandiswa glycerol inopisa-inonyungudika uye infrared inopisa-inonyungudika.
(2) Kuenzana kwemhepo inopisa.Iyo inozivikanwawo seti yekupfapfaidza, iyo solder mask-yakavharidzirwa yakadhindwa yedunhu bhodhi inokwenenzverwa nekuyerera nemhepo inopisa, yobva yapinda mudhamu resimbi yakanyungudutswa, yobva yapfuura nepakati pemapanga maviri emhepo kuti ibvise solder yakawandisa kuti iwane yakajeka, yunifomu, yakatsetseka. solder coating.Kazhinji, tembiricha yekugezera solder inodzorwa pa230 ~ 235, tembiricha yemhepo banga inodzorwa kumusoro kwe176, iyo dip welding nguva i5 ~ 8s, uye ukobvu hwekuputira hunodzorwa pa6 ~ 10 microns.
Kaviri Sided Yakadhindwa Circuit Board
Kana iyo PCB yakapetwa kaviri-sided redunhu bhodhi yakaraswa, haigone kudzokororwa, uye yayo yekugadzira mhando ichakanganisa zvakananga kunaka uye mutengo wechigadzirwa chekupedzisira.
