Nkhaniyi imakupatsirani chidziwitso chokwanira cha zofunikira za PCB zowotcha gulu komanso malingaliro opulumutsa mphamvu.Ndi vuto lalikulu lamphamvu padziko lonse lapansi komanso kulimbikitsa malamulo a chilengedwe, opanga ma PCB apereka zofunikira zapamwamba pazida zopulumutsa mphamvu.Kuphika ndi njira yofunika kwambiri pakupanga kwa PCB.Kugwiritsa ntchito pafupipafupi kumawononga magetsi ambiri.Choncho, kukweza zipangizo kuphika kuti patsogolo kusamala mphamvu yakhala imodzi mwa njira PCB opanga bolodi kupulumutsa mphamvu ndi kuchepetsa ndalama.
Kuphika pafupifupi kumadutsa munjira yonse ya PCB yopanga gulu ladera.Zotsatirazi zikuwonetsani zomwe mukufuna kuphika pakupanga ma board a PCB.
1. Njira zomwe zimafunikira pakuwotcha matabwa a PBC
1. Lamination, kukhudzana, ndi browning kupanga mkati wosanjikiza mapanelo amalowa mu kuyanika mu chipinda kuphika.
2. Kuwongolera, kupukuta ndi kupukuta pambuyo pa kuyanika kumafunika kuchotsa chinyezi, zosungunulira ndi kupsyinjika kwamkati, kukhazikika kwa kamangidwe ndi kupititsa patsogolo kumamatira, komanso kumafuna chithandizo chophika.
3. Mkuwa woyamba pambuyo pobowola uyenera kuphikidwa kuti ulimbikitse kukhazikika kwa njira ya electroplating.
4. Pre-mankhwala, lamination, kuwonetseredwa ndi chitukuko cha kunja wosanjikiza kupanga zonse amafuna kuphika kutentha kuyendetsa zochita za mankhwala kusintha ntchito zinthu ndi processing zotsatira.
5. Kusindikiza, kuphika chisanadze, kuwonekera, ndi chitukuko pamaso solder chigoba amafuna kuphika kuonetsetsa bata ndi kumamatira kwa solder chigoba zinthu.
6. Pickling ndi kusindikiza pamaso kusindikiza malemba amafuna kuphika kulimbikitsa zochita mankhwala ndi kukhazikika zinthu.
7. Kuphika pambuyo pa chithandizo chapamwamba cha OSP ndikofunikira kuti zinthu za OSP zikhazikike komanso kumamatira.
8. Iyenera kuphikidwa musanayambe kuumba kuti iwonetsetse kuuma kwa zinthu, kupititsa patsogolo kumamatira ndi zipangizo zina, ndikuwonetsetsa kuti kuumba.
9. Musanayambe kuyesedwa kwa probe yowuluka, kuti mupewe zolakwika ndi zolakwika zomwe zimayambitsidwa ndi chikoka cha chinyezi, kukonza kuphika kumafunikanso.
10. Chithandizo chophika musanayambe kufufuza kwa FQC ndikuteteza chinyezi pamtunda kapena mkati mwa bolodi la PCB kuti zotsatira za mayeso zikhale zolakwika.
2. Njira yophika nthawi zambiri imagawidwa m'magawo awiri: kuphika kotentha kwambiri ndi kuphika kocheperako:
1. Kutentha kwambiri kophika nthawi zambiri kumayendetsedwa mozungulira 110°C, ndipo nthawiyo ndi pafupifupi maola 1.5-4;
2. Kutentha kwa kutentha kochepa kumayendetsedwa pafupifupi 70°C, ndipo nthawi yayitali ndi maola 3-16.
3. Pakuwotcha kwa board ya PCB, zida zotsatirazi zophikira ndi kuyanika ziyenera kugwiritsidwa ntchito:
Ovuni yowongoka, yopulumutsa mphamvu, mzere wodziwikiratu wonyamula zowotcha, uvuni wa infuraredi ndi zida zina zosindikizidwa za PCB board board.
Mitundu yosiyanasiyana ya zida za uvuni ya PCB imagwiritsidwa ntchito pazosowa zosiyanasiyana zophika, monga: plugging board hole ya PCB, kuphika chophimba chosindikizira cha solder, chomwe chimafuna ntchito zazikulu zodzichitira zokha.Mavuvuni opulumutsa mphamvu nthawi zambiri amagwiritsidwa ntchito kupulumutsa anthu ambiri komanso zinthu zakuthupi pomwe akugwira ntchito bwino.Kuchita bwino kuphika, kutenthetsa kwambiri komanso kugwiritsa ntchito mphamvu zamagetsi, zachuma komanso zachilengedwe, zimagwiritsidwa ntchito kwambiri m'magawo a board board kwa solder chigoba chisanadze kuphika ndi zolemba pambuyo pophika matabwa a PCB;kachiwiri, ndi zambiri ntchito kuphika ndi kuyanika PCB bolodi chinyezi ndi nkhawa mkati.Ndi uvuni wozungulira wowotcha wokhala ndi zida zotsika mtengo, zotsika pang'ono komanso zoyenera kuwotcha ma multilayer flexible.
4. PCB wozungulira bolodi kuphika njira, uvuni malangizo zipangizo:
Mwachidule, ndizosapeŵeka kuti opanga ma board a PCB ali ndi zofunikira zapamwamba komanso zapamwamba pamilingo yopulumutsa mphamvu ya zida.Ndilo malangizo ofunikira kwambiri kuti apititse patsogolo mphamvu zopulumutsa mphamvu, kupulumutsa ndalama komanso kukonza luso la kupanga pogwiritsa ntchito kukweza kapena kusintha zida zophikira.Mavuvuni opulumutsa mphamvu amakhala ndi mwayi wopulumutsa mphamvu, kuteteza chilengedwe, komanso kugwiritsa ntchito bwino mphamvu, ndipo amagwiritsidwa ntchito kwambiri pakadali pano.Kachiwiri, mauvuni ozungulira mpweya wotentha ali ndi maubwino apadera pama board apamwamba a PCB omwe amafunikira kuphika kwaukhondo komanso ukhondo monga ma board onyamula a IC.Kuphatikiza apo, ali ndi kuwala kwa infrared.Zowotchera ngalande ndi zida zina zamavuni pano ndizoyanika ndi kuchiritsa okhwima.
Monga mtsogoleri pazachitetezo cha mphamvu, Xinjinhui amapitiliza kupanga zatsopano ndikusintha zinthu moyenera.Mu 2013, kampaniyo inakhazikitsa m'badwo woyamba wa PCB zolemba pambuyo pophika mumsewu wosindikizira, zomwe zidapangitsa kuti ntchito yopulumutsa mphamvu ndi 20% ikhale yabwino poyerekeza ndi zida zachikhalidwe.Mu 2018, kampaniyo idakhazikitsanso uvuni wachiwiri wa PCB wophika mumsewu, womwe udakwaniritsa kukweza kwa 35% pakupulumutsa mphamvu poyerekeza ndi m'badwo woyamba.Mu 2023, ndi kafukufuku wopambana ndi chitukuko cha ma patent angapo opanga ndi matekinoloje atsopano, mphamvu yopulumutsa mphamvu ya kampaniyo yakwera mpaka 55% poyerekeza ndi m'badwo woyamba, ndipo yakondedwa ndi makampani ambiri apamwamba 100 mu PCB. makampani, kuphatikizapo Jingwang Electronics.Makampaniwa ayitanidwa ndi Xin Jinhui kuti akachezere ndikulumikizana ndi mapanelo oyesa mafakitale.M'tsogolomu, Xinjinhui idzayambitsanso zipangizo zamakono.Chonde khalani tcheru, ndipo ndinu olandiridwa kutiyimbira foni kuti tikambirane ndikupanga nthawi yoti mudzatichezere kuti tizilankhulana maso ndi maso.
