The Pcb bhodhi tinowanzoona ane mavara mazhinji. Muchokwadi, mavara aya anogadzirwa nekudhinda akasiyana PCB solder masks. Common mavara muPCB redunhu bhodhi solder chifukidzo vari girini, dema, tsvuku, bhuruu, chena, yero, etc. Vanhu vakawanda vanoda kuziva, chii musiyano pakati pemavara aya akasiyana redunhu mapuranga?

Ingave bhodhi redunhu pane mudziyo wemagetsi, nharembozha mamaboard kana komputa motherboard, PCB redunhu mabhodhi anoshandiswa. Kubva pakuonekwa kwemaonero, mabhodhi ePCB edunhu anouya mumarudzi akasiyana-siyana, girinhi yakajairika, inoteverwa nebhuruu, tsvuku, dema, chena zvichingodaro.

Hazvina mhosva kuti bhodhi redunhu rakafanana nenhamba yemhando ipi, basa rayo rakafanana. Mabhodhi edunhu emavara akasiyana anoratidza kuti ruvara rwe solder mask inoshandiswa rwakasiyana. Basa guru remasolder mask ndeyekuisa pane solder mask kuvhara waya kuti insulate uye kudzivirira mapfupi maseketi. Green inowanzoonekwa, nekuti munhu wese anoshandiswa kushandisa girini solder mask inki yemapuranga edunhu, uye vanogadzira masiki vanogadzira kazhinji vanogadzira mamwe mafuta egirinhi, uye mutengo uchave wakaderera pane mamwe mavara ingi. , Anenge ese ari mustock. Ehe, vamwe vatengi vanozodawo mamwe mavara, akadai dema, tsvuku, yero, nezvimwewo, saka ivo vanofanirwa kudhindwa nemamwe mavara emasolder mask.

Iyo inki paPCB redunhu bhodhi, kazhinji kutaura, zvisinei neruvara rwemasolder mask, basa rayo harina kunyanya kusiyana. Musiyano mukuru ndiwo musiyano wekuona. Kunze kwemavara machena anoshandiswa paaluminium substrate uye backlight, pachava nemusiyano wakajeka mukuratidzira kwechiedza, uye mamwe mavara anoshandiswa pakuchengetedza solder nekudzivirira kwekudzivirira.

Iyo solder masikisi yemavara akasiyana anodhindwa pabhodhi redunhu. Kunyangwe mutsauko webasa usiri mukuru, pachine misiyano mishoma. Chekutanga ndechekuti inoratidzika zvakasiyana. Subconsciously, ndinonzwa kuti dema nebhuruu zvakanyanyisa-kuguma, uye zvinodiwa zvichave zvakakwirira. Nekudaro, mapuranga edunhu anoshandisa green solder mask akajairika zvekuti anonzwa akajairika. Mazhinji mapaneru anoshandisa green solder mask. Kuenzaniswa nemutema, hazvisi nyore kuona mutsara wemutsara, uye kuvhara kuchava nani, izvo zvinogona kudzivirira kutevedzera vezera kune imwe nhanho. Muchena unoratidza chiedza zviri nani, uye unowanzo shandiswa kuvheneka kana kuvheneka.

Mazhinji emasolder masks anoshandiswa mumabhodhi edunhu akasvibira, uye masiki ekutengesa anoshandiswa munharembozha anochinjika antenna mabhodhi akanyanya dema nechena. Iyo wiring board uye kamera module board inonyanya kushandisa yero solder kuramba inki, uye bhaa bhodhi rinoshandisa chena kana matt chena solder kuramba inki.

Kazhinji kutaura, ndeupi ruvara solder kuramba inki inoshandiswa paPCB inotsamira zvakanyanya pane zvinodiwa nemutengi wefekitori yedunhu bhodhi. Ruvara haruna zvakawanda mhedzisiro pakuita. Zvishoma ndezvekuti kana iyo photosensitive solder kuramba inki ikashandiswa, kazhinji zviri nyore kuve chena. Kunze kwechisimbiso chemufirimu. Pane inochinjika redunhu bhodhi, iyo chena solder mask haina kushingirira kukotama pane mamwe mavara.

Kunewo mamwe masikisi emasoja pamapuranga edunhu ane mavara anokosha. Mazhinji eaya akakosha emavara solder masiki anogadzirwa nevagadziri veinki, uye mamwe anosanganiswa nemhando mbiri dzemasolder mask ingi mune imwe chikamu. Yakasanganiswa kunze (mamwe mafekitori makuru ebhodhi redunhu, iyo mafuta blender mukati inogadzirisa ruvara)

Hazvina mhosva kuti PCB solder inorambira ingi ruvara rwakaita sei, inofanirwa kunge iine kudhinda kwakanaka uye kugadziriswa, kuitira kuti isangane nezvinodiwa sirika skrini uye zvinodiwa zvekugadzira fekitori.
