2.Nthawi yowotcherera yosakwanira komanso kutentha kosakwanira.
3.The oxide filimu pamwamba si kuchotsedwa.
Kutentha kwambiri
Mawonekedwe:zolumikizira zoyera zogulitsira, zopanda zitsulo zonyezimira, zowoneka bwino.
Zowopsa:Padiyo ndi yosavuta kupukuta ndipo mphamvu imachepa.
Kusanthula zomwe zimayambitsa:
Mphamvu ya chitsulo chosungunulira ndi yayikulu kwambiri ndipo nthawi yotentha ndi yayitali kwambiri.
Kuwotcherera kozizira
Mawonekedwe:Pamwamba pake pamakhala tinthu tating'onoting'ono tomwe timakhala ngati ufa, ndipo nthawi zina pamakhala ming'alu.
Zowopsa:otsika mphamvu, osauka madutsidwe magetsi.
Kusanthula zomwe zimayambitsa:Pali jitter pamaso pa solder olimba.
Kulowa molakwika
Mawonekedwe:Maonekedwe pakati pa solder ndi weldment ndi yaikulu kwambiri osati yosalala.
Zowopsa:otsika kwambiri, palibe kugwirizana kapena kugwirizana kwapakatikati.
Kusanthula Chifukwa:
1.Kuwotcherera sikoyera.
2.Kusakwanira kapena kutsika kwabwino.
3.Weldments satenthedwa mokwanira.
Asymmetrical
Mawonekedwe:The solder sikuyenda pa pad.
Zowopsa:Mphamvu zosakwanira.
Kusanthula Chifukwa:
1.Solder fluidity si yabwino.
2.Kusakwanira kapena kutsika kwabwino.
3.Kutentha kosakwanira.
kumasuka
Mawonekedwe:Mawaya kapena zigawo zotsogolera zimatha kusunthidwa.
Zowopsa:kusayenda bwino kapena kusayenda bwino.
Kusanthula Chifukwa:
1.Kutsogolera kumasuntha solder isanayambe kulimba, kuchititsa voids.
2.Zotsogolera sizinakonzekere bwino (zosauka kapena zosanyowa).
Kunola
Mawonekedwe:Kuwonekera kwa nsonga.
Zowopsa:mawonekedwe osauka, zosavuta kuyambitsa bridging chodabwitsa.
Kusanthula Chifukwa:
1.Kuthamanga kochepa kwambiri komanso nthawi yayitali yotentha.
2.Ngodya ya chitsulo chosungunula kuti achoke ndi yosayenera.
Kulumikizana
Mawonekedwe:Mawaya oyandikana nawo amalumikizidwa.
Zowopsa:Magetsi afupikitsa.
Kusanthula Chifukwa:
1.Kugulitsa kwambiri.
2.Ngodya ya chitsulo chosungunula kuti achoke ndi yosayenera.
chipini
Mawonekedwe:Pali mabowo omwe amawonekera ndi kuyang'ana kowoneka kapena kukulitsa kochepa.
Zowopsa:Mphamvu zosakwanira, zolumikizira za solder ndizosavuta kuwononga.
Kusanthula zomwe zimayambitsa:Kusiyana pakati pa nsonga ndi bowo la pad ndi lalikulu kwambiri.
Bambo
Mawonekedwe:Muzu wa lead umakhala ndi chotupa chotulutsa mpweya, ndipo mkati mwake muli bowo.
Zowopsa:Kuwongolera kwakanthawi, koma ndikosavuta kuyambitsa kusayenda bwino kwa nthawi yayitali.
Kusanthula Chifukwa:
1. Kusiyana pakati pa kutsogolera ndi dzenje la pad ndi lalikulu.
2.Poor lead tonyowetsa.
3.Nthawi yowotcherera ya bolodi yokhala ndi mbali ziwiri kudzera m'mabowo ndi yaitali, ndipo mpweya m'mabowo ukuwonjezeka.
Wapolisipa zojambulazo zimakwezedwa
Mawonekedwe:Chojambula chamkuwa chimachotsedwa pa bolodi losindikizidwa.
Zowopsa:Bolodi losindikizidwa lawonongeka.
Kusanthula zomwe zimayambitsa:Nthawi yowotcherera ndi yayitali komanso kutentha kumakhala kokwera kwambiri.
Peel
Mawonekedwe:Zolumikizira zogulitsira zimachotsedwa pachojambula chamkuwa (osati zojambulazo zamkuwa ndi bolodi losindikizidwa).
Zowopsa:Tsegulani dera.
Kusanthula zomwe zimayambitsa:Kuyika kwachitsulo kosakwanira pa pedi.
Pambuyo pofufuza zomwe zimayambitsaPCB msonkhano solderingzolakwika, tili ndi chidaliro kukupatsirani kuphatikiza kwabwino kwambirikutembenukira kiyi PCB msonkhano msonkhano, khalidwe, mtengo ndi nthawi yobweretsera mu dongosolo lanu la Small batch voliyumu ya PCB ndi Mid batch Volume PCB dongosolo la msonkhano.
Ngati mukuyang'ana wopanga msonkhano wabwino wa PCB, chonde tumizani mafayilo anu a BOM ndi mafayilo a PCB kwa sales@pcbfuture.com.Mafayilo anu onse ndi achinsinsi kwambiri.Tikutumizirani mawu olondola okhala ndi nthawi yotsogolera mu maola 48.
