Kodi Pali Kusiyana Kotani Pakati pa Wave Soldering Machine ndi Manual Welding?

Mu makampani amagetsi, PCBA processing zipangizo mapulogalamu ndimakina opangira ma wave solderingndi kuwotcherera pamanja.Kodi pali kusiyana kotani pakati pa njira ziwirizi zowotcherera, zabwino ndi zoyipa zake ndi ziti?

I. Ubwino Wowotcherera Ndi Kuchita Bwino Ndiwotsika Kwambiri

1. Chifukwa cha kugwiritsa ntchito ERSA, OK, HAKKO ndi crack ndi chitsulo china chanzeru chanzeru chamagetsi, kuwotcherera kwabwino kwasinthidwa, koma pali zovuta zina zowongolera.Mwachitsanzo, kuchuluka solder ndi kuwotcherera kunyowetsa ngodya ulamuliro, kuwotcherera kugwirizana, zofunika za mlingo malata kudzera dzenje metallized.Makamaka pamene chigawo chotsogolera ndi golide-chokutidwa ndi golide, m'pofunika kuchotsa golidi ndi malata akalowa pa gawo lomwe likufunika kuwotcherera tini kutsogolo pamaso kuwotcherera, chimene chiri chinthu chovuta kwambiri.

2. Kuwotcherera pamanja kumakhalanso zinthu zaumunthu ndi zofooka zina, n'zovuta kukwaniritsa zofunikira zapamwamba;Mwachitsanzo, ndi kuwonjezeka kwa kachulukidwe gulu gulu ndi kuwonjezeka makulidwe a bolodi dera, kuwotcherera mphamvu kutentha ukuwonjezeka, ndi soldering chitsulo kuwotcherera n'zosavuta kutsogolera kutentha osakwanira, mapangidwe kuwotcherera pafupifupi kapena kudzera dzenje solder kukwera. kutalika sikukwaniritsa zofunikira.Ngati kutentha kwa kuwotcherera kukuchulukirachulukira kapena nthawi yowotcherera italikirana, ndikosavuta kuwononga bolodi losindikizidwa ndikupangitsa kuti pad igwe.

3. Traditional soldering chitsulo amafuna anthu ambiri ntchito mfundo kuwotcherera mfundo pa PCBA.Selective wave soldering imagwiritsa ntchito zokutira zotulutsa, kenako kutenthetsa bolodi / flux, ndiyeno kugwiritsa ntchito chowotcherera potengera njira yowotcherera.Njira yopangira batch ya mafakitale yamzere wa msonkhano imatengedwa.Kuwotcherera nozzles zazikulu zosiyanasiyana akhoza kuwotcherera mu magulu ndi kuukoka kuwotcherera.The kuwotcherera dzuwa zambiri nthawi zambiri kuposa kuwotcherera pamanja.

II.Wave Soldering Wapamwamba Kwambiri

1. kuwotcherera mafunde, kuwotcherera, kuwotcherera magawo olowa aliyense solder akhoza "ogwirizana", ndi zokwanira ndondomeko kusintha malo pa malo aliwonse kuwotcherera zinthu, monga flux wa kupopera mbewu mankhwalawa kuchuluka, kuwotcherera nthawi, kuwotcherera funde kutalika ndi mafunde kutalika chosinthika kuti bwino. , zolakwika zitha kuchepetsedwa kwambiri zitha kutheka kudzera muzitsulo za dzenje zero defect powotcherera, The defect rate (DPM) ya selective wave soldering ndiyotsika kwambiri poyerekeza ndi soldering pamanja, through-hole reflow soldering ndi ochiritsira wave soldering.

2. kuwotcherera yoweyula chifukwa cha ntchito programmable mafoni yamphamvu yaing'ono malata ndi zosiyanasiyana kusinthasintha kuwotcherera nozzle, kotero mu ndondomeko kuwotcherera akhoza anakonza kupewa zina zomangira zina zomangira ndi kulimbikitsa mbali ya PCB B mbali, kuti musagwirizane ndi mkulu kutentha solder ndi kuwononga, palibe chifukwa makonda thireyi kuwotcherera ndi njira zina.

3. Kuchokera poyerekeza pakati pa kuwotcherera kwa mafunde ndi kuwotcherera pamanja, tikhoza kuona kuti kuwotcherera kwa mafunde kuli ndi ubwino wambiri monga kutsekemera kwabwino, kusinthasintha kwakukulu, kusinthasintha kwamphamvu, kuchepa kwa chilema, kuipitsidwa kochepa ndi kusiyanasiyana kwa zigawo zowotcherera.
