Oomatshini bokuphawula nge-laser yefayibha basebenzisa umqadi we-laser onamandla aphezulu ogxile ngqo kumphezulu we-PCB. Isiphumo sobushushu siyayitshisa okanye siyitshise intsimbi okanye iileya zokugquma, sikrola iipateni ezincinci, umbhalo, okanye sisuse iileya ezingaphezulu ngokuchanekileyo, nto leyo eyenza ukuba ilungele iisekethe ezintsonkothileyo kunye neeleya ezincinci.

Njengenkqubo yokungachukumisi, uphawu lwelaser lususa ukuguguleka koomatshini, lugcina umphezulu wePCB. Ukongeza, aludingi zisombululo zokugrumba ngeekhemikhali, luqinisekisa inkqubo yokuvelisa enobuhlobo nokusingqongileyo nesebenzayo.

Oomatshini bokuphawula i-laser yefayibha bagxila kwi-laser enamandla aphezulu kumphezulu wekhadi le-SD, okubangela utshintsho lombala (njengokubola kwe-oxidation okanye ubushushu) okanye utshintsho lokwakheka komphezulu ngeziphumo zobushushu, okwenza ukuba iimpawu zibonakale.

Le nkqubo iqinisekisa ukuchaneka okuphezulu kunye nokuqina, ithintela ukuguguleka okanye ukususwa, okwenza ukuba ilungele ukusetyenziswa ixesha elide kunye nokuchongwa kwesixhobo sokugcina esithembekileyo kakhulu.

Oomatshini bokuphawula nge-laser ye-CO₂ basebenzisa umqadi we-laser we-infrared we-10.6μm ukwenza iimpawu kwiindawo zemodyuli yememori. Xa zijoliswe kwi-PCB, isiphumo sobushushu obunamandla aphezulu siyafudumeza, sidibanise, okanye sibolise izinto, nto leyo ebangela utshintsho lombala olwenza uphawu oluhlala luhleli.

Njengenkqubo yokungadibani, uphawu lwelaser aluchaphazeli ukusebenza kombane okanye amandla okugcina idatha kwimodyuli yememori. Ubushushu obuxineneyo buhlala phezu komphezulu, buqinisekisa ukuba akukho mpembelelo kwiitships okanye iisekethe zangaphakathi, kugcina ukuthembeka kwemveliso kunye nokuthembeka kwayo.

Oomatshini bokuphawula nge-laser ye-UV bafaka iimpawu kwiitships ezifakwe kwi-epoxy resin besebenzisa umthombo wokukhanya obandayo, nto leyo evumela ukuba uphawu luchaneke kakhulu kwaye lube nefuthe elincinci kubushushu. Oku kuthintela umonakalo wobushushu kwitships nakwizakhiwo ezingqongileyo, kuqinisekisa inkqubo yokuphawula ekhuselekileyo kunye nokuthembeka kwezinto.

Ngoxinzelelo oluphezulu lwamandla, ii-laser ze-UV zisusa ngokuchanekileyo umphezulu we-epoxy resin, zenze iimpawu ezibukhali nezihlala ixesha elide. Oku kuphucula kakhulu ukulandeleka kweetshiphusi ngelixa kugcinwa uzinzo lokupakishwa kunye nomgangatho wemveliso.

I-PA (iPolyamide, edla ngokuba yinylon) isetyenziswa kakhulu kwiibhloko ze-terminal ze-elektroniki, zeemoto, nezemizi-mveliso ngenxa yokumelana kwayo nokuguguleka, ukumelana neekhemikhali, amandla aphezulu oomatshini, kunye neempawu zokuthintela ubushushu bombane.

Ukumakishwa kwelaser yefayibha kudla ngokusebenzisa imisebe yelaser enobude obufutshane, enobunzima obuphezulu (umz., 1064nm). Xa ijoliswe kumphezulu we-PA, amandla aqokelelweyo abangela ukusabela kobushushu, okubangela ukuba izinto zekhabhoni kwizinto zinyibilike kwaye zenze umaleko omnyama ofakwe ikhabhoni. Le nkqubo ibolisa izinto eziphilayo, isuse umswakama kunye nokuguquguquka, kwaye ishiye uphawu olumnyama olutyebileyo kwikhabhoni, iqinisekisa umahluko ophezulu kunye nokufundeka kakuhle xa kuthelekiswa nezinto ze-PA.

Ukuphawula nge-laser ye-UV kudala iimpawu ezihlala zihleli nezibonakala kakhulu kwiindawo zokugcina i-optocoupler ngokusebenzisa i-carbonization kunye nokubola kobushushu. Le nkqubo iqinisekisa ukuchaneka okuphezulu, umahluko onamandla, kunye nokuqina okugqwesileyo. Ukuphawula nge-laser ye-UV kusetyenziswa kakhulu ekuchongeni okusisigxina, kwiinombolo ze-serial, okanye kwiilogo zenkampani kwiindawo zokugcina i-optocoupler, ngakumbi kwizicelo zoshishino neze-elektroniki, ukuqinisekisa ukucaca okuhlala ixesha elide kunye nozinzo.
