Indlela yokusombulula ingxaki ye Ibhodi PCB i-laminate yobhedu

Nazi ezinye zeengxaki zebhodi yesekethe ye-PCB edla ngokudibana nendlela yokuqinisekisa. Nje ukuba udibane neengxaki ze-laminate ye-PCB, kufuneka ucinge ngokuyongeza kwi-PCB ye-laminate material specication. Oku kulandelayo kuchaza indlela yokusombulula ingxaki yebhodi yesekethe ye-PCB yebhodi yobhedu ene-laminate?

PCB ibhodi yesekethe copper clad laminate ingxaki enye. Ukuze ukwazi ukulandelela kwaye ufumane

Akunakwenzeka ukuvelisa naliphi na inani leebhodi zesekethe ze-PCB ngaphandle kokuhlangabezana neengxaki ezithile, ezibangelwa ubukhulu becala kwizinto ze-laminate yobhedu ye-PCB. Xa iingxaki zomgangatho zisenzeka kweyona nkqubo yokuvelisa, kubonakala ngathi kaninzi kuba i-PCB substrate imathiriyeli iba ngunobangela wengxaki. Nkqu ebhalwe ngononophelo kwaye iphunyezwe ngokwezenzo PCB laminate iinkcukacha zobugcisa ayikhankanyi izinto zovavanyo ekufuneka zenziwe ukumisela ukuba PCB laminate unobangela iingxaki inkqubo yemveliso. Nazi ezinye zeengxaki ezixhaphakileyo ze-laminate PCB kwaye zichonge njani.

Nje ukuba udibane neengxaki ze-laminate ye-PCB, kufuneka ucinge ngokuyongeza kwi-PCB ye-laminate material specication. Ngokuqhelekileyo, ukuba le nkcazo yobugcisa ayizalisekanga, iya kubangela utshintsho oluqhubekayo lwekhwalithi kwaye ngenxa yoko lukhokelela ekukhutshweni kwemveliso. Ngokuqhelekileyo, iingxaki zezinto ezibonakalayo ezivela kwiinguqu kumgangatho we-PCB laminates zenzeka kwiimveliso eziveliswa ngabavelisi abasebenzisa iibhetshi ezahlukeneyo zemathiriyeli ekrwada okanye ukusebenzisa imithwalo yocinezelo eyahlukeneyo. Bambalwa abasebenzisi abaneerekhodi ezaneleyo ukuze bakwazi ukwahlula imithwalo ethile ecinezelayo okanye iibhetshi zemathiriyeli kwindawo yokucubungula. Ngenxa yoko, kuyenzeka ukuba ii-PCBs ziveliswa ngokuqhubekayo kwaye zixhonywe ngamacandelo, kwaye ii-warps ziqhubeka ziveliswa kwitanki ye-solder, echitha umsebenzi omningi kunye namacandelo exabiso. Ukuba inombolo yebhetshi yezinto zokulayisha inokufumaneka ngokukhawuleza, umenzi we-laminate we-PCB unokuqinisekisa inani lebhetshi ye-resin, inombolo yebhetshi yefoyile yobhedu, kunye nomjikelo wokunyanga. Ngamanye amazwi, ukuba umsebenzisi akakwazi ukubonelela ngokuqhubekayo kunye nenkqubo yokulawula umgangatho we-PCB umenzi we-laminate, oku kuya kubangela ukuba umsebenzisi ngokwakhe alahlekelwe yilahleko yexesha elide. Oku kulandelayo kwazisa imiba jikelele enxulumene substrate imathiriyeli kwinkqubo yokwenziwa kwebhodi yesekethe PCB.

PCB ibhodi yesekethe copper clad laminate ingxaki ezimbini. Ingxaki yomphezulu

Iimpawu: ukuncamatheliswa kakubi koshicilelo, ukuncamathela okungalunganga kweplating, ezinye iindawo azinakubekwa kude, kwaye ezinye iindawo azinakuthengiswa.

Iindlela zokuhlola ezikhoyo: ngokuqhelekileyo zisetyenziselwa ukwenza imigca yamanzi ebonakalayo kumphezulu webhodi ukuze kuhlolwe okubonakalayo:

isizathu esinokwenzeka:

Ngenxa yendawo exineneyo kakhulu kwaye egudileyo eyenziwe yifilimu yokukhululwa, indawo yobhedu engafakwanga iqaqambe kakhulu.

Ngokuqhelekileyo kwicala elingabonakaliyo le-laminate, umenzi we-laminate akasusi i-agent agent.

Imingxunya kwi-foil yobhedu ibangela ukuba i-resin iphume kwaye iqokelele phezu kwephepha lobhedu. Oku ngokuqhelekileyo kwenzeka kwi-foil yobhedu encinci kune-3/4 ye-ounce yobunzima.

Umenzi wefoyile yobhedu unxiba umphezulu wefoyile yobhedu ngezixa ezigqithisileyo ze-antioxidants.

Umenzi we-laminate utshintshe inkqubo ye-resin, ukuhluba okuncinci, okanye indlela yokuxubha.

Ngenxa yokusebenza ngendlela engafanelekanga, kukho iminwe emininzi okanye amabala egrisi.

Dipha nge-oyile ye-injini ngexesha lokubetha, ukuvala okanye ukugrumba.

Izisombululo ezinokubakho:

Ngaphambi kokwenza naluphi na utshintsho kwimveliso ye-laminate, sebenzisana nomenzi we-laminate kwaye ucacise izinto zokuvavanya komsebenzisi.

Kucetyiswa ukuba abavelisi be-laminate basebenzise iifilimu ezifana nelaphu okanye ezinye izinto zokukhulula.

Qhagamshelana nomenzi we-laminate ukuhlola ibhetshi nganye yefoyile yobhedu engafanelekanga; cela isisombululo esicetyiswayo sokususa i-resin.

Buza umenzi we-laminate ngendlela yokususa. U-Changtong ucebisa ukuba kusetyenziswe i-hydrochloric acid, elandelwa kukukhuhla ngoomatshini ukuyisusa.

Qhagamshelana nomenzi we-laminate kwaye usebenzise iindlela zokuphelisa oomatshini okanye iikhemikhali.

Ukufundisa abasebenzi kuzo zonke iinkqubo zokunxiba iiglavu ukuphatha i-laminates ezenziwe ngobhedu. Fumana ukuba i-laminate ithunyelwa ngepadi efanelekileyo okanye ifakwe kwisikhwama, kwaye i-pad inomxholo ophantsi wesulfure, kwaye isikhwama sokupakisha sikhululekile kumdaka. Qaphela ukuba akukho mntu uyichukumisayo xa usebenzisa i-silicone ene-detergent ye-Copper foil.

Degrease zonke laminates phambi plating okanye inkqubo yokudlulisa iphethini.
