16 mtunduzawamba PCBsolderingzolakwika
Mu PCB msonkhano ndondomeko, zosiyanasiyana zofooka nthawi zambiri kuonekera, monga soldering zabodza, kutenthedwa, mlatho ndi zina zotero.Pansipa PCBfuture ifotokoza zachilendoMsonkhano wa PCBzolakwika zikagulitsa ma PCB ndi momwe mungapewere.
1. Kuwotchera zabodza
Mawonekedwe: pali malire akuda pakati pa solder ndi chigawo chotsogolera, kapena zojambulazo zamkuwa, ndipo solder imadutsa malire.
Kuvulaza: kusagwira ntchito bwino.
Chifukwa: kutsogolera kwa zigawo zake sikutsukidwa, malata samakutidwa kapena malata ndi oxidized.Bolodi losindikizidwa silimatsukidwa, ndipo mtundu wa kupopera mbewu mankhwalawa si wabwino.
2. Solder kudzikundikira
Mawonekedwe: mawonekedwe olumikizana ndi solder ndi otayirira, oyera komanso osawoneka bwino.
Zovulaza: Kusakwanira kwamakina mphamvu kungayambitse kuwotcherera zabodza.
Chifukwa: osauka solder khalidwe.Kutentha kowotcherera sikokwanira.Pamene solder siimalimba, gawo lotsogolera limakhala lotayirira.
3. Solder kwambiri
Mawonekedwe: pamwamba pa solder ndi convex.
Zovulaza: solder yawonongeka ndipo zolakwika sizingawonekere mosavuta.
Chifukwa: olakwika ntchito pa soldering.
4. Solder pang'ono
Mawonekedwe: malo owotcherera ndi ochepera 80% a pad, ndipo solder sipanga malo osinthika osalala.
Kuvulaza: kusakwanira mphamvu zamakina.
Chifukwa: kusuntha kwa solder ndikosowa kapena kuchotsedwa msanga kwa solder.Kuthamanga kosakwanira.Nthawi yowotcherera ndiyofupika.
5. Rosin kuwotcherera
Mawonekedwe: pali rosin slag mu weld.
Kuvulaza: mphamvu zosakwanira, kusayendetsa bwino, nthawi zina kuyatsa ndi kuzimitsa.
Chifukwa: pali makina owotcherera ambiri kapena kulephera kwa welder.Nthawi yowotcherera yosakwanira ndi kutentha.Filimu ya oxide pamwamba sinachotsedwe.
6. Kutenthedwa
Mawonekedwe: cholumikizira choyera cha solder, chopanda chitsulo chonyezimira, pamwamba pake.
Zovulaza: Pad ndi yosavuta kupukuta ndipo mphamvu imachepa.
Chifukwa: mphamvu ya chitsulo chosungunuka ndi yaikulu kwambiri, ndipo nthawi yotentha ndi yaitali kwambiri.
7. Kuwotcherera kozizira
Mawonekedwe: Pamwamba pake ndi granular, ndipo nthawi zina pangakhale ming'alu.
Kuvulaza: Mphamvu zochepa komanso kusayenda bwino.
Chifukwa: solder imagwedezeka isanakhazikike.
8. Kulowa molakwika
Mawonekedwe: mawonekedwe pakati pa solder ndi weldment ndiakulu kwambiri komanso osasalala.
Zovulaza: mphamvu zochepa, palibe mwayi wofikira kapena kutseka nthawi.
Chifukwa: kuwotcherera sikutsukidwa.Flux ndiyosakwanira kapena yabwino.Kuwotchera sikutenthedwa kwathunthu.
9. Asymmetric
Mawonekedwe: solder sikuyenda pamwamba pa pedi.
Kuvulaza: Kusakwanira mphamvu.
Chifukwa: solder imakhala ndi madzi ochepa.Kuthamanga kosakwanira kapena kusakwanira bwino.Kutentha kosakwanira.
10. Womasuka
Mawonekedwe: Waya kapena gawo lotsogolera limatha kusunthidwa.
Kuononga: kusachita bwino kapena kusachita bwino.
Chifukwa: Solder isanayambe kulimba, waya wotsogolera amasuntha kuti apangitse voids.Kuwongolera sikukonzedwa bwino.
11. Kup
Mawonekedwe ake: akuthwa.
Kuvulaza: Kusawoneka bwino, kosavuta kuyambitsa mlatho
Chifukwa: kusinthasintha pang'ono komanso nthawi yayitali yotentha.Kuchoka kwa chitsulo chosungunuka ndi kosayenera.
12. Kulumikizana
Mawonekedwe: mawaya oyandikana amalumikizidwa.
Kuvulaza: Magetsi afupikitsa.
Chifukwa: solder kwambiri.Ngongole yolakwika ya kubweza chitsulo cha soldering.
13. Khomo
Mawonekedwe: kuyang'ana kowoneka kapena ma amplifiers otsika amatha kuwona mabowo.
Zovulaza: mphamvu zosakwanira, olowa solder osavuta kuwononga.
Chifukwa: kusiyana pakati pa chiwongolero ndi dzenje la pad ndi lalikulu kwambiri.
14. Mvula
Mawonekedwe a mawonekedwe: pali chowotcha chowotcha moto pamizu ya chiwongolero, ndipo chibowo chimabisika mkati.
Zovulaza: Kuwongolera kwakanthawi, koma ndikosavuta kuyambitsa kusayenda bwino kwa nthawi yayitali.
Chifukwa: kusiyana pakati pa kutsogolera ndi kuwotcherera chimbale dzenje ndi lalikulu.Kulowa molakwika kwa lead.Nthawi yowotcherera yokhala ndi mbali ziwiri kumabowo ndi yayitali, ndipo mpweya m'mabowo umakula.
15. Chojambula chamkuwa chopindika
Mawonekedwe: zojambulazo zamkuwa zimachotsedwa pa bolodi losindikizidwa.
Zovulaza: PCB yawonongeka.
Chifukwa: nthawi yowotcherera ndi yayitali kwambiri ndipo kutentha kumakwera kwambiri.
16. Avule
Mawonekedwe: zolumikizira zogulitsira zimachotsedwa pachojambula chamkuwa (osati zojambulazo zamkuwa ndi PCB).
Zovulaza: Tsegulani dera.
Chifukwa: zitsulo zokutira zoipa pa pad.
PCBFuture imapereka ntchito zonse zophatikizira za PCB, kuphatikiza kupanga PCB, kufufuza zinthu ndi kusonkhana kwa PCB.ZathuTurnkey PCB serviceimachotsa kufunikira kwanu koyang'anira othandizira angapo nthawi zingapo, zomwe zimapangitsa kuti pakhale ntchito yabwino komanso yotsika mtengo.Monga kampani yoyendetsedwa bwino, timayankha mokwanira zosowa za makasitomala, ndipo titha kupereka ntchito zapanthawi yake komanso zaumwini zomwe makampani akulu sangathe kutengera.Titha kukuthandizani kupewa kuwonongeka kwa PCB kugulitsa zinthu zanu.
