Ngaba i-PCB igqityiwe xa uyilo lugqityiwe kwaye akukho ngxaki zifunyenweyo ngoqhagamshelwanokunye nesithuba?
Kakade ke, impendulo nguhayi. Uninzi lwabaqalayo, kuquka iinjineli ezinamava, ngenxa yexesha elincinci okanye ukuphelelwa ngumonde okanye ukuzithemba kakhulu,
ithande ukungxama, ukungahoyi ukhangelo kade, bekukho ezinye iziphene ezisezantsi kakhulu, ezinje ngobubanzi bomgca awanelanga, izixhobo zoshicilelo lwelebhile.
uxinzelelo kunye nemingxuma yokuphuma yayisondele kakhulu, imiqondiso kwi-loop, njl., ikhokelela kwiingxaki zombane okanye inkqubo, ibhodi yokudlala enzulu, inkcitho. Ngoko ke,
emva kokuhlolwa linyathelo elibalulekileyo emva kokuba PCB sele ibekwe.
1. Ukupakishwa kwecandelo
(1) Isithuba sepadi. Ukuba sisixhobo esitsha, ukuzoba iphakheji yabo yamacandelo, qinisekisa ukuba isithuba sifanelekile. Isithuba sePad sichaphazela ngokuthe ngqo i-welding yamacandelo.
(2) Ngobukhulu (ukuba bukhona). Kwizixhobo ze-plug-in, ubukhulu bomngxuma kufuneka bugcinwe umda owaneleyo, ngokuqhelekileyo ungekho ngaphantsi kwe-0.2mm ifanelekile.
(3) Umzobo wesikrini sesilika. Ushicilelo lwescreen secontour lwamacandelo kufuneka lube
inkulu kunobukhulu bokwenyani ukuqinisekisa ukuba isixhobo sinokufakelwa kakuhle.
2. Uyilo
(1) I-IC ayifanele ibe kufutshane nomphetho webhodi.
(2) Amacandelo esekethe kwimodyuli enye kufuneka abekwe ngokusondeleyo omnye komnye. Ngokomzekelo, i-capacitor decoupling kufuneka ibe
kufutshane nephini yonikezelo lwamandla ye-IC, kwaye amacandelo abandakanya isekethe efanayo esebenzayo kufuneka abekwe kwindawo efanayo kunye noluhlu olucacileyo.
ukuqinisekisa ukufezekiswa kwemisebenzi.
(3) Lungiselela indawo yesokhethi ngokufakela kwangempela. I-Socket iqhagamshelwe kwezinye iimodyuli ngokukhokela, ngokwesakhiwo sokwenyani,
ukuze ufakele ukulungelelana, sebenzisa ngokubanzi indawo ekufutshane yolungiselelo lwesiseko, kwaye ngokubanzi kufutshane nomphetho webhodi.
(4) Nikela ingqalelo kwisalathiso sokuphuma. I-Socket idinga ulwalathiso, ukuba ulwalathiso luchasene, ucingo kufuneka lwenziwe. Kwisiseko esisicaba, ukuqhelaniswa nesokethi kufuneka kube kwicala elingaphandle kwebhodi.
(5) Makungabikho zixhobo kwindawo yogcino.
(6) Umthombo wokuphazamiseka kufuneka ube kude kwisekethe ebuthathaka. Isiginali yesantya esiphezulu, iwotshi yesantya esiphezulu okanye isiginali yokutshintsha yangoku ephezulu yimithombo yokuphazamiseka, kufuneka ibe kude nesekethe ebuthathaka (efana nokuseta ngokutsha isekethe, isekethe ye-analog). Ziyakwazi ukuhlukaniswa ngumgangatho.
