Ukuze wenze lula ukukhiqizwa kanye nokukhiqiza, i-PCBPCB BOOL Circuit Board Gigsaw ngokuvamile kufanele iklame iphoyinti le-Mark, i-V-Groove, kanye nokusebenza kwamandla.
Idizayini yokubukeka kwe-PCB
1
2. Ububanzi obuphelele be-PCB Splicing Method yi-≤260mm (umugqa we-Nokia!) Noma ≤300mm (umugqa we-fuji); Uma kudingeka i-automatic gluing, ububanzi obuphelele be-PCB Splicing Method yi-125mm × 180mm.
3. Ukuklanywa kokubukeka kwendlela ye-PCB Boarding kusondelene nesikwele ngangokunokwenzeka, futhi kunconywe kakhulu ukusebenzisa 2 × 2, 3 × 3, ... kanye nendlela yokugibela; Kepha akudingekile ukupela amabhodi amahle namangele;
ukusikwa kwe-PCBV
1. Ngemuva kokuvula ukusikwa kwe-V, ubukhulu obusele x kufanele kube (1/4 ~ 1/3) ubukhulu bepuleti l, kepha ubukhulu obuncane x kumele bube ≥0.4mm. Imikhawulo iyatholakala ngamabhodi anemithwalo esindayo, futhi imikhawulo ephansi iyatholakala ngamabhodi anezitha ezilula.
2. I-spacement sin inxeba ngakwesobunxele nangakwesokudla kwezinhlangothi ze-V-cut kufanele ibe ngaphansi kuka-0 mm; Ngenxa yomkhawulo omncane wobukhulu obuncane, indlela ye-V-Cut Splicing ayifanele iBhodi ngobukhulu obungaphansi kwe-1,3mm.
Iphuzu leMark
1. Lapho usetha iphuzu lokukhetha elijwayelekile, ngokuvamile phuma endaweni engahambisani ne-1.5 mm enkulu kunengxenye yephuzu lokukhetha.
2. Isetshenziselwa ukusiza i-Optics ye-elekthronikhi yomshini wokubekwa kwe-SMT ukuze uthole ukuthola kahle ekhoneni eliphezulu lebhodi le-PCB nge-Chip Contnex. Kukhona okungenani amaphuzu amabili okulinganisa ahlukene. Amaphuzu wokulinganisa wokuma okunembile kwe-PCB evamile ngokuvamile engxenyeni eyodwa. Isikhundla esihlobene ekhoneni eliphezulu le-PCB; Amaphoyinti wokulinganisa wokuma okuqondile kwe-PCB Ectronic Optics ngokuvamile ekhoneni eliphezulu le-PCB PCB Circuit Bholi.
I-3. Ngezakhi ze-QFP (Iphakheji eliyisikwele) nge-wire spacesing ≤0.5 mm kanye ne-BGA (I-Ball Grid Array Package) nge-Ball Spacering
Iyacubungula uhlangothi lwezobuchwepheshe
1 Ukuqinisekisa ukusebenza okujwayelekile kwama-laser cutting CNC blades.
Ukubeka izimbobo eziqondile ebhodini
1. Isetshenziselwa ukuma okunembile kwebhodi lonke le-PCB yeBhodi Yesekethwa kwePCBPCB kanye namamaki ajwayelekile wokuma okunembile kwezinto ezinhle ezihlukaniswe kahle. Ngaphansi kwezimo ezijwayelekile, i-QFP enesikhathi sokuphumula esingaphansi kuka-0.65mm kufanele isethwe ekhoneni layo ephezulu; Amamaki ajwayelekile okubeka izinto ze-PCB yendodakazi yeBhodi kufanele asetshenziswe ngababili futhi abekwe emakhoneni aphezulu ezinto eziqondile zokuma.

Umklami we-PCB omuhle kufanele acabangele izakhi zokukhiqiza nokwenza lapho ethuthukisa uhlelo lokuklama iphazili ukuqinisekisa ukukhiqizwa nokusebenza okulula, ukuthuthukisa umkhiqizo, nokunciphisa izindleko zomkhiqizo.
