Oonobangela bomphezulu womhlaba ngaphakathi ibhodi yesekethe Mveliso

IBhodi umphezulu amagwebu yenye iziphene umgangatho esemgangathweni kwinkqubo yemveliso PCB. Ngenxa yokuntsonkotha kwenkqubo yemveliso PCB kunye nenkqubo yolondolozo, ingakumbi unyango imichiza emanzi, kunzima ukukhusela ibhodi umphezulu amagwebu iziphene. Ngokusekwe kwiminyaka emininzi yamava emveliso kunye namava enkonzo, umbhali ngoku wenza uhlalutyo olufutshane ngezizathu zokutshiza ebusweni bebhodi yesekethe eyityhubele ngobhedu, ngethemba lokuba iya kuba luncedo koontanga kwishishini!

Ingxaki yokutshiza kumgangatho webhodi yebhodi yesekethe eneneni yingxaki yokubambelela okungalunganga komphezulu webhodi, kwaye ke yingxaki yomgangatho wobuso kumphezulu webhodi, obandakanya imiba emibini:

1. Ucoceko lomgangatho webhodi;

2. Umphezulu woburhabaxa obuncinci (okanye amandla omphezulu); Zonke iingxaki zokubhabha kumphezulu webhodi kwiibhodi zesekethe zinokushwankathelwa njengezizathu zingasentla. Ukuncamathela phakathi kwento yokunxiba kubi okanye kuphantsi kakhulu. Kunzima ukuxhathisa uxinzelelo lokutyabeka, uxinzelelo loomatshini kunye noxinzelelo lwe-thermal oluveliswe kwimveliso nakwinkqubo yokulungisa kwimveliso elandelayo kunye nenkqubo yokuqhubekeka kunye nenkqubo yokuhlangana, okukhokelela ekwahlukaneni kwendlela yokuhombisa.

Ezinye zezinto ezinokubangela umgangatho weplate ongekho mgangathweni ngexesha lokuveliswa kunye nokulungiswa kushwankathelwe ngolu hlobo lulandelayo:

1. Iingxaki zenkqubo yenkqubo ye-substrate; Ngokukodwa kwezinye ii-substrates ezibhityileyo (ngokubanzi zingaphantsi kwe-0.8mm), ngenxa yokuqina kwe-substrate, ayifanelekanga ukuba ibrashi ipleyiti ngomatshini webrashi, engenakususa ngokufanelekileyo umaleko wokhuselo ophathwe ngokukodwa ukunqanda igcwala ngefoyile ye yobhedu kumphezulu ipleyiti ngexesha imveliso kunye nokulungiswa zeendawana. Nangona umaleko ubhityile kwaye ipleyiti yebrashi kulula ukuyisusa, kunzima ukwamkela unyango lweekhemikhali, ke ngoko, kubalulekile ukuba unikele ingqalelo kulawulo kwimveliso nakwinkqubo, ukuthintela ingxaki enegwebu ebangelwe kukunamathela okungalunganga phakathi I-substrate foil foil kunye nobhedu lweekhemikhali; Xa umnyama ungqimba lwangaphakathi olucekeceke, kuya kubakho iingxaki, njengokumnyama okungacacanga kunye nokumdaka, umbala ongalinganiyo kunye nombala omnyama wendawo omnyama.

2. Ibala leoyile okanye olunye ungcoliseko lolwelo, ungcoliseko lothuli kunye nonyango olungalunganga lomhlaba olubangelwa kukumanziswa kwepleyiti (ukubhola, ukondla, ukuguba komphetho, njl.).

3. Itafile yebrashi eshiyekileyo yokuhambisa ubhedu: uxinzelelo lwesityana sokugaya ngaphambi kokufakwa kobhedu luphezulu kakhulu, okukhokelela ekuguqulweni kwe-orifice, ukukhupha i-foil foil ye-orifice kunye nokuvuza izinto ezisisiseko ze-orifice, eya kuthi ibangele igwebu le-orifice ngexesha lokufakwa kobhedu, ukufakela i-electroplating, ukutshiza i-tin kunye ne-welding; Nokuba ipleyiti yebrashi ayivuzi i-substrate, ipleyiti enzima yebrashi iya kubonyusa uburhabaxa bobhedu kwi-orifice. Ke ngoko, kwinkqubo yokubola okuncinci, ifoyile yobhedu kule ndawo kulula kakhulu ukuyigcoba ngokugqithileyo, kwaye kuya kubakho ubungozi obufihliweyo bomgangatho; Ke ngoko, ingqalelo kufuneka ihlawulwe ekomelezeni ulawulo lwenkqubo yeplashi yebrashi. Inkqubo yeplani yeplashi yebrashi inokuhlengahlengiswa kweyona ilungileyo ngokuvavanywa kwenqaku lokuvavanya kunye novavanyo lwefilimu yamanzi.

4. Ingxaki yokuhlamba amanzi: ngenxa yokuba unyango lobhedu lokunyusa i-electroplating ludinga unyango oluninzi lwamachiza, kukho iintlobo ezininzi ze-acid-base, non-polar organic kunye nezinye izixazululi zamayeza, kwaye umphezulu weplate awuhlanjwanga ngokucocekileyo. Ngokukodwa, uhlengahlengiso lwe-arhente yokwahlulwa kokufakwa kubhedu ayizukubangela ungcoliseko nje kuphela, kodwa iya kukhokelela kunyango lwasekhaya olubi okanye isiphumo sonyango olubi kunye neziphene ezingalinganiyo kumgangatho wepleyiti, okukhokelela kwiingxaki ezithile ekubambeleleni; Ke ngoko, kufuneka kuthathelwe ingqalelo ukomeleza ulawulo lokuhlanjwa kwamanzi, ngakumbi kubandakanya nolawulo lokucoca ukuhamba kwamanzi, umgangatho wamanzi, ixesha lokuhlamba amanzi, ixesha lokuthoba ipleyiti njalo njalo; Ngokukodwa ebusika, xa ubushushu buphantsi, isiphumo sokuhlamba siya kuncitshiswa kakhulu. Ingqwalaselo engaphezulu kufuneka ihlawulwe kulawulo olomeleleyo lokuhlamba.

5.Umhlwa omncinci ekubunjweni kobhedu kunye nephethini yokuthanjiswa kwangaphambili; Ukugqithisa okuncinci okugqithisileyo kuya kubangela ukuvuza kwe-substrate kwi-orifice kunye ne-blisting ejikeleze i-orifice; Ukungoneli okwaneleyo okuncinci kuya kukhokelela kumbane ongonelangayo wokubopha kunye ne-bubble phenomenon; Ke ngoko, ulawulo lwentambo encinci kufuneka luqiniswe; Ngokubanzi, ubuncinci bokutsalwa kobuncinci bokubekwa kwindawo yokuhambisa ubhedu yi-1.5-2 microns, kunye nobunzulu obuncinci beepatheni zokwenza i-electroplating prereatment yi-0.3-1 microns. Ukuba kunokwenzeka, kungcono ukulawula ubungqingqwa obuncinci bokubamba okanye inqanaba lokutsalwa ngohlalutyo lweekhemikhali kunye novavanyo olulula lobunzima; Ngokubanzi, umbala wobuso bepleyiti eqaqambe ngokuqaqambileyo, ipinki efanayo, ngaphandle kokubonisa; Ukuba umbala awulingani okanye ubonakalisa, kubonisa ukuba kukho ubungozi obunokubakho kumgangatho ophambi kokulungiswa kwenkqubo yokuvelisa; Nika ingqalelo ekuqiniseni ukuhlolwa; Ukongeza, umxholo wobhedu, ubushushu bokuhlamba, umthwalo kunye nomxholo omncinci weetanki ezincinci kufuneka uhlawulwe.

6. Umsebenzi wesisombululo semvula sobhedu unamandla kakhulu; Umxholo wezinto ezintathu eziphambili kwisilinda esandula ukuvulwa okanye itanki yolwelo lwesisombululo semvula sobhedu siphezulu kakhulu, ngakumbi umxholo wobhedu uphezulu kakhulu, nto leyo eya kuthi ibangele iziphene zomsebenzi onamandla kakhulu wetanki yolwelo, ukubekwa koburhabaxa bemichiza erhabaxa, ukufakwa okugqithileyo hydrogen, cuprous oxide njalo-njalo kubume beekhemikhali zobhedu, okukhokelela ekwehleni komgangatho wepropathi ebonakalayo kunye nokubambelela okungalunganga kwengubo; Ezi ndlela zilandelayo zinokwamkelwa ngokufanelekileyo: ukunciphisa umxholo wobhedu, (ukongeza amanzi acocekileyo kulwelo lwetanki) kubandakanya izinto ezintathu, ukwandisa ngokufanelekileyo umxholo we-arhente entsonkothileyo kunye nokuzinzisa, kunye nokunciphisa ngokufanelekileyo iqondo lobushushu lolwelo lwetanki.

7. Ukuxutywa kweplate yomhlaba ngexesha lokuvelisa; Ukuba ipleyiti yokuntywila yobhedu ifakwe ioksijini emoyeni, ayinokubangela kuphela ubhedu emngxunyeni kunye nomphezulu wepleyiti erhabaxa, kodwa ikwanokubangela ukudumba kumphezulu weplate; Ukuba ipleyiti yobhedu igcinwe kwisisombululo seasidi ixesha elide, umphezulu wepleyiti uya kuthi kwakhona ube ne-oxidized, kwaye le filimu ye-oxide kunzima ukuyisusa; Ke ngoko, kwinkqubo yokuvelisa, isitya sobhedu kufuneka siqiniswe ngexesha. Akufanele igcinwe ixesha elide. Ngokubanzi, isaleko sobhedu kufuneka siqiniswe kwisithuba seeyure ezili-12 kutshanje.

8. Ukungasebenzi kakuhle kwedipozithi yobhedu; Ezinye iipleyiti zisetyenzisiwe emva kokufakwa kobhedu okanye ukuguqulwa kwepateni kuya kubangela ukutshiza kumgangatho weplate ngenxa yokuma okungcolileyo, indlela yokuphinda iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde isetyenziswe; Ukuphinda usebenzise ipleyiti yokuntywila ngobhedu ukuba kufunyenwe isiphene kumjelo wobhedu, inokususwa ngqo emgceni emva kokuhlanjwa kwamanzi, iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde iphinde isebenze ngaphandle komhlwa emva kokukhethwa; Kungcono ukuba ungasusi ioyile kwakhona kwaye ukhukulise kancinci; Kwiipleyiti eziqiniswe ngombane, i-micro etching groove kufuneka icime ngoku. Nika ingqalelo kulawulo lwexesha. Unokubala ixesha elitshabalalayo ngepleyiti enye okanye ezimbini ukuqinisekisa isiphumo sokubuna; Emva kokuba isingxobo sisuswe, iqela lebrashi ethambileyo yokugaya emva komatshini webrashi iya kusetyenziselwa ukuxubha ukukhanya, emva koko ubhedu luya kufakwa ngokwenkqubo yesiqhelo yemveliso, kodwa ixesha lokurhaxwa kunye nokukrola kancinci kuya kuncitshiswa okanye kulungelelaniswe iyimfuneko.

9. Ukuhlanjwa kwamanzi okungonelanga emva kophuhliso, ixesha elide lokugcina emva kokuphuhliswa okanye uthuli oluninzi kwindawo yokusebenzela kwinkqubo yokudlulisa imifanekiso kuya kubangela ukucoceka kwebhodi engalunganga kunye nefuthe lokunyanga ifayibha elibi, elinokubangela iingxaki ezisemgangathweni.

10. Phambi kwesingxobo sobhedu, itanki yokukhetha iya kutshintshwa ngexesha. Ungcoliseko oluninzi kulwelo lwetanki okanye umxholo wobhedu ophakamileyo aluyi kubangela kuphela ingxaki yokucoceka kweplate, kodwa kunokubangela neziphene ezinje ngoburhabaxa beplate.

11. Ungcoliseko lwezinto eziphilayo, ngakumbi ungcoliseko lweoyile, lwenzeka kwitanki yokubilisa, enokubakho kumgca wokuzenzekelayo.

12.
