Imiqathango yoShicilelo lweBhodi yePCB: Isikhokelo se-Ink yeMaski yeSolder

Yazisa:

Xa kuveliswa iibhodi zesekethe eziprintiweyo (PCBs), ukusebenzisa izixhobo ezifanelekileyo kunye nobuchule kubalulekile ekuqinisekiseni ukusebenza kakuhle kunye nokuthembeka. Inkalo ebalulekileyo yokuveliswa kwe-PCB kukusetyenziswa kwe-inki ye-mask ye-solder, enceda ukukhusela umkhondo wobhedu kunye nokuthintela iibhulorho ze-solder ngexesha lokuhlanganisa. Nangona kunjalo, ukufumana iziphumo ezigqibeleleyo zoshicilelo lwebhodi yePCB, izilumkiso ezithile mazilandelwe.Kule post blog, siza kuxubusha izilumkiso eziyimfuneko ekufuneka ziqwalaselwe xa uphethe i-inks zemaski ze-solder, sichaza izinto eziphambili zokugcina umgangatho ophezulu kunye nokusebenza.

1. Khetha i-inki yesigqubuthelo semaski efanelekileyo:

Ukukhetha i-inki ye-mask ye-solder efanelekileyo ibalulekile ekufezekiseni ukugqiba okuthembekileyo kunye nokuhambelana. Ngokufanelekileyo, i-inki ekhethiweyo kufuneka ibonelele ngokugqwesileyo kumphezulu we-PCB, ibe nokumelana nobushushu obuphezulu, kwaye ibe neempawu ezilungileyo zokugquma umbane. Izinto ezifana nebhodi yesekethe substrate, iimfuno inkqubo yokuvelisa, kunye neempawu PCB ezinqwenelekayo kufuneka ziqwalaselwe xa kusenziwa esi sigqibo sibalulekileyo.

2. Ukugcinwa nokuphathwa ngendlela eyiyo:

Nje ukuba i-inki ye-mask ye-solder ifunyenwe, ukugcinwa ngokufanelekileyo kunye nokuphatha kubalulekile ukugcina ukusebenza kwayo. Kucetyiswa ukuba ugcine i-inki kwindawo epholileyo, eyomileyo kude nelanga elithe ngqo kunye nokutshintsha kobushushu obugqithisileyo. Qinisekisa ukuba isikhongozeli sivalekile xa singasetyenziswa ukunqanda ukomisa okanye ukungcoliseka kwe-inki. Amanyathelo afanelekileyo okuphatha, afana nokunxiba iiglavu kunye nokuthatha amanyathelo okuthintela ukuchithwa kunye nokudibanisa kwesikhumba, kufuneka kusetyenziswe ukuqinisekisa ukhuseleko lomntu kunye nokugcina ingqibelelo ye-inki.

3. Unyango lomphezulu:

Ukufezekisa isicelo esigqibeleleyo se-inki ye-solder kufuna ukulungiswa okucokisekileyo komhlaba. Phambi kokufaka i-inki, umphezulu wePCB kufuneka ucocwe ukususa naziphi na izinto ezingcolisa ezifana nothuli, igrisi, okanye iminwe. Ubuchule bokucoca obufanelekileyo, obufana nokusebenzisa izicoci ezikhethekileyo zePCB namalaphu angena-lint, kufuneka asetyenziswe ukuqinisekisa umphezulu ococekileyo. Naziphi na iincinci ezishiyekileyo okanye ukungcola okushiywe ebhodini kuya kuchaphazela kakubi ukunamathela kunye nokusebenza ngokubanzi kweyinki.

4. Ukuqwalaselwa kwemiba yokusingqongileyo:

Iimeko zokusingqongileyo zidlala indima ebalulekileyo ekuqinisekiseni ukusetyenziswa kwe-inki yesigqubuthelo se-solder. Imiba efana nobushushu kunye nokufuma kufuneka ibekwe iliso elibukhali kwaye ilawulwe phakathi koluhlu oluchaziweyo ngumenzi we-inki. Iimeko ezigqithisileyo okanye eziguquguqukayo zokusingqongileyo zinokuchaphazela i-ink viscosity, ixesha lokumisa kunye neempawu zokubambelela, okukhokelela kwiziphumo ezibi zokuprinta. Ukulinganisa rhoqo izixhobo zolawulo lokusingqongileyo kuyacetyiswa ukugcina iimeko ezifunekayo kuyo yonke inkqubo yePCB yokuvelisa.

5. Itekhnoloji yesicelo:

Ukusetyenziswa ngokufanelekileyo kwe-inki yemaski ye-solder kubalulekile ekuphumezeni iziphumo ezifunwayo. Qwalasela ukusebenzisa izixhobo ezizisebenzelayo ezifana noomatshini bokuprinta kwesikrini okanye iindlela ze-inkjet zokuqinisekisa ukhuseleko oluchanekileyo noluhambelanayo. Kulumkele ukufaka ubungakanani obuchanekileyo be-inki ukuqinisekisa ukugqunywa okupheleleyo, kodwa hayi ubukhulu obukhulu. Ulawulo olululo lokuhamba kwe-inki, ukucinezeleka kwesikrini, kunye noxinzelelo lwe-squeegee (kwimeko yoshicilelo lwesikrini) kuya kunceda ukufikelela kubhaliso oluchanekileyo kwaye kuthintele iziphene ezinje ngemingxuma, ukopha, okanye ukubopha ibhulorho.

6. Ukunyanga kunye nokomisa:

Inyathelo lokugqibela kwinkqubo yesicelo se-inki yemaski ye-solder kukuphilisa kunye nokomisa. Landela izikhokelo zomenzi malunga nobushushu obufanelekileyo kunye nobude bexesha elifunekayo ukuze i-inki inyange ngokufanelekileyo. Kuphephe ukufudumeza okukhawulezileyo okanye ukupholisa njengoko oku kunokubangela uxinzelelo okanye ukuncipha komgangatho we-inki enyangisiweyo. Qinisekisa ixesha elaneleyo lokomisa phambi kokuba uqhubeke neenkqubo ezilandelayo zokuvelisa ezifana nokubekwa kwecandelo okanye i-soldering. Ukugcina ukungaguquguquki kunyango kunye nokomisa iiparamitha kubalulekile ekufumaneni imaski ye-solder efanayo kunye neyomeleleyo.

Ukuququmbela:

Xa ujongana ne-inks yemaski ye-solder, ukuthatha izilumkiso eziyimfuneko ngexesha lenkqubo yoshicilelo lwebhodi yePCB kubalulekile ekuqinisekiseni umgangatho ophezulu, iziphumo ezithembekileyo nezihlala ixesha elide. Ngokukhetha ngokucokisekileyo i-inki ye-mask ye-solder echanekileyo, ukuziqhelanisa nokugcinwa ngokufanelekileyo kunye nokuphatha, ukulungiselela ngokufanelekileyo umphezulu, ukulawula iimeko zokusingqongileyo, ukusebenzisa iindlela ezichanekileyo zokusetyenziswa, kunye nokulandela iinkqubo ezicetyiswayo zokunyanga kunye nokomisa, abavelisi banokuvelisa ii-PCB ezingenasiphako ngelixa begcina inkqubo yokuvelisa. Ukubambelela kwezi zilumkiso kunokwandisa kakhulu amandla oshishino lokwenziwa kwePCB, kunciphise iziphene, kwaye kwandise ukwaneliseka kwabathengi.
