Nawa amanye amathiphu ochwepheshe okuthi usenza kanjani lesi sinqumo:
1. Ukufinyeleleka
Mayelana nokuqhathanisa phakathi kwe-HASL engaholwanga ne-HASL eholayo, singasho ukuthi eyokuqala ibiza kakhulu.Ngakho-ke, uma unesabelomali esiqinile noma ufuna ukonga imali, ukuya ekuqedeni okuholayo kwe-HASL kuyindlela engcono yokonga imali.
2. Ukuthobela i-RoHS
Uma kubhekwa izinkinga zempilo kanye nokulimala komzimba okuhlotshaniswa nokusetshenziswa kwezinto zikagesi, ukujula kokuchayeka okulethwa ukuhlolwa kwebhodi lesekethe kumsebenzisi kuyafaneleka.
Ukuthobela i-RoHS manje kuyindinganiso yamaphrojekthi amaningi e-PCB futhi iningi labathengi liyanaka kulokhu.Ngalesi sizathu, ukukhetha imikhiqizo engenamthofu we-HASL kuyinketho engcono uma ufuna ukwenza amabhodi wesekethe athobela i-RoHS.
Lokhu kungenxa yokugcwala okukhulu kwethini kanye nenani elincane lethusi.Njengoba ungekho umthofu osetshenziswayo lapha, ungaqiniseka ukuthi izindaba ezingezinhle zezempilo oziphakamisayo aziyona into ongazikhathaza ngayo.
Isici esibalulekile sempumelelo, nokho, ukuthi zingekho izingxenye zephimbo elihle ku-PCB.Izingxenye ezifana nama-BGA nama-SMD azilungile kulokhu.
3. Izidingo zokuqina
Ngaphezu kokuvikela ithusi nezinye izakhi ezibalulekile, umsebenzi wokwelapha ongaphezulu kufanele udlulele ekuthuthukiseni ukuqina kwe-PCB.Uma ibhodi lihlala liqinile ngenxa yokusetshenziswa kwalo, lizohlala isikhathi eside.
4. Isicelo kanye nokusebenza
Isicelo, okungukuthi lapho ibhodi eligcotshwe nganoma iyiphi yalezi ziphetho lizosetshenziswa, kubalulekile ukucatshangelwa.Ngalesi sizathu, isicelo noma isimo sokusebenzisa kufanele sinakwe ukuze kusizwe ukukhetha okufanele.
5. Cabangela indawo ezungezile
Ungaphambanisi imvelo nohlelo lokusebenza noma icala lokusebenzisa.Ngokwemvelo lapha sisho uhlobo noma izinga lokuchayeka okungenzeka ukuthi ibhodi lesekethe eliphrintiwe (PCB) lizovezwa kulo uma selimbozwe ngokuqeda.
Imvelo ngokuvamile ibhekisela ezingeni lokushisa - kungakhathaliseki ukuthi linokhahlo noma lithambile.Ukuze uthole imiphumela engcono kakhulu, sebenzisa imikhiqizo engenamthofu ye-HASL njengoba ithobela i-RoHS, okuyenza ibe nobungane kubo bobabili umsebenzisi nendawo ezungezile.
6. Khetha i-ENIG ngaphezu kwe-HASL yokwelapha ngaphandle komthofu
Izinketho ezintathu (3) eziphambili eziphambi kwakho zokuqeda i-PCB i-HASL, i-HASL Lead Free kanye ne-ENIG.Nakuba lezi zinto ezintathu zinezakhiwo ezihlukene, eyodwa ingase ibe ukukhetha okungcono kunezinye.
Okokuqala, kufanele ukhethe i-HASL engenawo umthofu kune-HASL ngoba ihambisana ne-RoHS, okusho ukuthi kungenzeka ukuyisebenzisela uhla olubanzi lokuqedwa kwe-PCB.Iqiniso lokuthi linikeza ukuthengiselana okuhle kakhulu kungenye indawo yokuthengisa.
Ngakolunye uhlangothi, uma ufuna ukonga imali futhi usebenze kuma-PCB adinga amazinga okushisa aphansi, i-HASL iyisinqumo esihle.
Uma ungenaso isiqiniseko sokuthi kokubili i-HASL engenawo umthofu kanye ne-HASL izowenza umsebenzi, khona-ke ukukhetha igolide lokucwilisa i-electroless nickel (ENIG) iyona ndlela engcono kakhulu.Ngaphezu kwalokho, i-ENIG icishe ifane ne-HASL engenamthofu, njengokuthobela i-RoHS.
I-Zhejiang NeoDen Technology Co., Ltd. ibikhiqiza futhi ithumela kwamanye amazwe imishini emincane yokukhetha nendawo kusukela ngo-2010. Isebenzisa i-R&D yethu ecebile enokuhlangenwe nakho, ukukhiqizwa okuqeqeshwe kahle, i-NeoDen izuza idumela elihle kumakhasimende omhlaba wonke.
Sikholelwa ukuthi abantu abakhulu nozakwethu benza i-NeoDen inkampani enhle futhi ukuzibophezela kwethu Ekusunguleni, Ukuhlukahluka kanye Nokusimama kuqinisekisa ukuthi i-SMT automation ifinyeleleka kuwo wonke umuntu wokuzilibazisa yonke indawo.
