Menene dalilin da komai waldi na aka gyara?

SMD za ta sami lahani iri-iri iri-iri, alal misali, ɓangaren ɓangaren siyar da ba komai a ciki, masana'antar ta kira wannan sabon abu don abin tunawa.

Daya karshen bangaren warped haka haifar da abin tunawa m solder, shi ne da dama dalilai na samuwar.A yau, za mu bayyana musabbabin faruwar lamarin da wasu matakan ingantawa.

1.Solder manna firintaba lebur ba ne, ƙarshen pad ɗin ya fi tin, ƙarshen ɗaya ya rage tin

Wannan shi ne gaban karshen faci jawo, saboda m solder manna bugu, solder manna bugu a duka iyakar da kushin ba daya adadin, sakamakon da baya na waldi rushe lokaci ba iri daya ba, sakamakon tashin hankali ne. ba iri ɗaya ba, don haka ƙarshen ɗaya ya karkata don samar da siyar da babu kowa.

Hanya mafi kyau don inganta wannan ita ce ƙara SPI a bayan na'ura mai siyar da kayan bugawa, ƙoƙarin gano abin da ba daidai ba, guje wa kwarara zuwa walda sannan kuma matsalar, ta yadda aikin sake yin aiki yana cin lokaci da tsada.

2.Zaba da sanya injiɗorawa biyun iyakar ba a goge ko kashewa ba

Bayan daInjin SMDyana shanye jeri na bangaren, na iya sa bututun tsotsa ya sha karkacewa ko kamara ta karanta daidaitattun jeri na lamba don karkata saboda ciyarwar foda, don haka yana kaiwa ga sakawa wuri diyya, an saka ƙarshen kushin fiye, ƙarshen ɗaya shine. Posted ƙasa don bayyana wa pad a waje, don haka yana haifar da lokacin reflow waldi lokacin da lokacin zafi ya bambanta, lokacin hawan tin ya bambanta, yana haifar da tashin hankali daban-daban, yana haifar da warping.

Hanyar inganta wannan matsala, a gefe guda ita ce kula da faifan dutsen da kyamara akai-akai, guje wa shanyewa da sanya karkacewa.a daya bangaren, akwai kasafin kudin don samun aInjin SMT AOI, gano ingancin sanyawa.

3.Na'ura mai sake juyewamatsalar saitin lankwasa zafin wuta

Reflow soldering kanta yana da hudu zafin jiki zones, daban-daban zafin jiki zone rawa ne daban-daban, a preheating da kuma akai zazzabi mataki, wasu aka gyara na iya zama kusa da mafi girma aka gyara, ta haka sa daya gefen da za a mai tsanani mugun, a shiga dumama walda mataki, da zafin jiki ne daban-daban zuwa ga solder manna zafi narkewa lokaci ne daban-daban, bayyana a tsaye abin tunawa komai waldi.

Abubuwan da ke sama da dalilai guda uku sune abubuwan gama gari na abubuwan da aka lalata a tsaye kwamfutar hannu komai a cikin solder, idan a cikin tsarin samarwa, wannan sabon abu na iya kasancewa daga waɗannan bangarorin na gyara matsala.
