Indlela yokuklama isikhala sokuphepha se-PCB?
Isikhala sokuphepha esihlobene nogesi
1. Isikhala phakathi kwesekhethi.
Ngomthamo wokucubungula, isikhala esincane phakathi kwezintambo akufanele sibe ngaphansi kuka-4mil. Isikhala somugqa omncane yibanga ukusuka kolayini ukuya kolayini nomugqa uye kuphedi. Ngokukhiqizwa, inkulu futhi ingcono, ngokuvamile i-10mil.
2.Ububanzi bembobo yephedi nobubanzi
Ububanzi bephedi akumele bube ngaphansi kuka-0.2mm uma imbobo ibholwa ngomshini, futhi ingabi ngaphansi kuka-4mil uma imbobo ibholwa nge-laser. Futhi ukubekezelelana kobubanzi bembobo kuhluke kancane ngokusho kwepuleti, ngokuvamile kungalawulwa ngaphakathi kwe-0.05mm, ububanzi obuncane bephedi akufanele bube ngaphansi kuka-0.2mm.
3.Isikhala phakathi kwamaphedi
Isikhala kufanele singabi ngaphansi kuka-0.2mm ukusuka kuphedi uye kwelinye.
4.Isikhala phakathi kwethusi nonqenqema lwebhodi
Ibanga phakathi konqenqema lwethusi ne-PCB akumele libe ngaphansi kuka-0.3mm. Setha umthetho wokuhlukanisa izinto ekhasini lohlaka Lwebhodi Lemithetho-yemithetho
Uma ithusi libekwe endaweni enkulu, kufanele kube nebanga elinciphayo phakathi kwebhodi nonqenqema, okuvamise ukubekwa ku-20mil.Embonini yokuklama ye-PCB kanye nokukhiqiza, ngokujwayelekile, ngenxa yezici zemishini ye-PCB. ibhodi lesifunda eliqediwe, noma ukugwema ukwenzeka kokujiya noma ukujikeleza okufushane kukagesi ngenxa yesikhumba sethusi esivezwe onqenqemeni lwebhodi, onjiniyela bavame ukunciphisa ibhulokhi yethusi enendawo enkulu ngama-20mil ngokuhlobene nonqenqema lwebhodi, esikhundleni ebeka isikhumba sethusi kuze kufike emaphethelweni ebhodi.
Ziningi izindlela zokwenza lokhu, njengokudweba isendlalelo se-keepout onqenqemeni lwebhodi nokusetha ibanga lokugcina. Indlela elula yethulwa lapha, okungukuthi, amabanga ahlukene okuphepha asethelwe izinto zokubeka ithusi. Isibonelo, uma ukuhlukaniswa kokuphepha kwepuleti lonke kusethelwe ku-10mil, futhi ukubeka kwethusi kusethelwe ku-20mil, umphumela wokuncipha okungu-20mil ngaphakathi konqenqema lwepuleti ungafinyelelwa, futhi ithusi elifile elingase livele kudivayisi nalo lingaba isusiwe.
