ThePCB redunhu mabhodhitinowanzoona ane mavara mazhinji.Muchokwadi, mavara aya ese anogadzirwa nekudhinda akasiyana PCB solder kuramba ingi.Common mavara muna PCB redunhu bhodhi solder kuramba ingi vari girini, dema, dzvuku, zvitema, chena, yero, etc. Vanhu vakawanda vanoda kuziva, chii musiyano pakati redunhu mapuranga aya mavara akasiyana?
Ingave bhodhi redunhu pachinhu chemagetsi, nharembozha mamaboard kana komputa motherboard, zvese zvinoshandisa PCB circuit board.Kubva pakuonekwa kwemaonero, mabhodhi ePCB edunhu ane mavara akasiyana-siyana, girinhi yakajairika, inoteverwa nebhuruu, tsvuku, dema, chena zvichingodaro.
Mabhodhi ane nhamba imwe chete yechikamu ane basa rimwechete zvisinei kuti nderipi ruvara.Mabhodhi emavara akasiyana anoratidza mavara akasiyana e solder kuramba inki inoshandiswa.Basa guru reiyo solder kuramba inki ndeyekuiisa pane solder resist layer kuvhara waya dzekudzivirira uye kudzivirira mapfupi maseketi.Green inowanzoonekwa, nokuti munhu wose anoshandiswa kushandisa girini solder kuramba ingi kuita redunhu mapuranga, uye vagadziri solder kuramba ingi kazhinji kubereka mamwe mafuta akasvibira, uye mutengo achava yakaderera pane ingi mamwe mavara., dzinenge dzose dziri mustock.Zvechokwadi, vamwe vatengi vachadawo mamwe mavara, akadai sematema, tsvuku, yero, nezvimwewo, izvo zvinoda kudhindwa ne solder resist inks yemamwe mavara.
Iyo inki paPCB redunhu bhodhi, kazhinji kutaura, zvisinei kuti iyo solder inodzivisa ingi ndeipi, mhedzisiro yayo haina kusiyana zvakanyanya.Chikonzero chikuru kusiyana kwechiono.Kunze kwekuti chena inoshandiswa pane aluminium substrate uye backlight, pachava nemusiyano wekuvhenekera kwechiedza, uye mamwe mavara anoshandiswa kushambadzira uye kudzivirira kudzivirira.
Solder kuramba ingi dzemavara akasiyana anodhindwa pabhodhi redunhu.Kunyangwe pasina misiyano yakawanda mukushanda, pachine misiyano midiki.Chokutanga pane zvose, zvinoratidzika zvakasiyana.Subconsciously, ndinonzwa kuti dema nebhuruu zvakanyanya-yepamusoro, uye zvinodiwa zvichave zvakakwirira.Nekudaro, mapuranga edunhu anoshandisa green solder kuramba inki akawandisa, saka anonzwa akajairika.Mabhodhi mazhinji ane divi rimwe chete anoshandisa green solder kuramba inki.Kuenzaniswa neyo dema, hazvisi nyore kuona mutsara wemutsara, uye kushanda kwekuvhara kuchava nani, izvo zvinogona kudzivirira vaenzanisi kukopa bhodhi kune imwe nzvimbo.Muchena unoratidza chiedza zviri nani uye unowanzo shandiswa kuvheneka kana kuvheneka.
Iyo solder inopikisa inki inoshandiswa mumabhodhi mazhinji edunhu yakasvibira, uye iyo solder inoramba ingi inoshandiswa munhare mbozha inochinjika antenna board inonyanya dema nechena.Iyo tambo bhodhi uye kamera module bhodhi kazhinji inoshandisa yero solder kuramba inki, uye mwenje bhodhi bhodhi inoshandisa chena kana matte chena solder kuramba inki.
Kazhinji, ruvara rwe solder kuramba inki inoshandiswa paPCB inonyanya kuenderana nezvinodiwa nevatengi vefekitori yedunhu bhodhi.Dhinda firimu.Pamapuranga edunhu anochinjika, chena solder kuramba ingi hadzina kushingirira kukotama pane mamwe mavara.
Panewo mamwe solder kuramba ingi pamatunhu mapuranga ane anokosha mavara.Mazhinji solder anopikisa ingi yemuvara uyu wakasarudzika anogadzirwa nevagadziri veingi, uye mamwe anosanganiswa neaviri solder kuramba ingi mune imwe chikamu.Bvisa kunze (mune mamwe mafekitori makuru ebhodhi redunhu, maoiri ari mukati anogona kuipenda)
Hazvina mhosva kuti PCB solder inorambira ingi ruvara rwakaita sei, inofanirwa kunge iine kudhinda kwakanaka uye kugadziriswa, kuitira kuti isangane nefekitari inodhinda sikirini zvinodiwa uye zvinodiwa pakugadzirwa.
