Enqubweni yokukhiqiza ye-PCB, kunenye inqubo ebalulekile, okungukuthi, i-tooling strip. Ukubhukha unqenqema lwenqubo kubaluleke kakhulu ekucubungulweni kwesichibi se-SMT okulandelayo.
Ucu lwamathuluzi luyingxenye engezwe ezinhlangothini zombili noma ezinhlangothini ezine zebhodi le-PCB, ikakhulukazi ukusiza i-plug-in ye-SMT ukuthi ishise ibhodi, okungukuthi, ukwenza lula i-SMT SMT track track clamp ibhodi ye-PCB futhi igeleze phakathi kwebhodi. Umshini we-SMT SMT. Uma izingxenye eziseduze kakhulu nonqenqema lwethrekhi zimunca izingxenye kumlomo womshini we-SMT SMT futhi zizinamathisele ebhodini le-PCB, isenzakalo sokushayisana singenzeka. Ngenxa yalokho, ukukhiqizwa akukwazi ukuqedwa, ngakho-ke umugqa othile wamathuluzi kufanele ugcinwe, ububanzi obujwayelekile obungu-2-5mm. Le ndlela ibuye ifanele ezinye izingxenye ze-plug-in, ngemva kokuhlanganisa amagagasi ukuvimbela izenzakalo ezifanayo.
Uhlu lwamathuluzi aluyona ingxenye yebhodi le-PCB futhi lungasuswa ngemva kokuqedwa kokwenziwa kwe-PCBA
Indlela yekhiqiza i-tooling strip:
I-1, V-CUT: uxhumano lwenqubo phakathi komugqa wamathuluzi nebhodi, ukusika kancane nhlangothi zombili zebhodi le-PCB, kodwa hhayi ukusika!
2, Imigoqo yokuxhuma: sebenzisa imigoqo eminingana ukuxhuma ibhodi le-PCB, wenze izimbobo zezitembu phakathi nendawo, ukuze isandla siphuke noma sigezwe ngomshini.
Akuwona wonke amabhodi e-PCB adinga ukungeza umugqa wamathuluzi, uma isikhala sebhodi le-PCB sikhulu, ungashiyi izingxenye ze-patch ngaphakathi kwe-5mm nhlangothi zombili ze-PCB, kulokhu, asikho isidingo sokwengeza umugqa wamathuluzi, kukhona futhi icala pcb ibhodi ngaphakathi 5mm ngakolunye uhlangothi akukho patch izingxenye, inqobo nje ukwengeza tooling strip ngakolunye uhlangothi. Lezi zidinga ukunakwa konjiniyela be-PCB.
Ibhodi elisetshenziswa umugqa wamathuluzi lizokhuphula izindleko zizonke ze-PCB, ngakho-ke kuyadingeka ukulinganisa umnotho nokwenziwayo lapho uklama unqenqema lwenqubo ye-PCB.
Kwezinye izimo ezikhethekile zebhodi le-PCB, ibhodi le-PCB elinamathuluzi angu-2 noma angu-4 lingenziwa lula kakhulu ngokuhlanganisa ibhodi ngobuhlakani.
Ekucutshungulweni kwe-SMT, idizayini yemodi yokubhoboza idinga ukucabangela ngokugcwele ububanzi bethrekhi bomshini wokubhoboza we-SMT. Ebhodini lokubhoboza elinobubanzi obudlula u-350mm, kuyadingeka ukuxhumana nonjiniyela wezinqubo zomphakeli we-SMT.
