Iyi ngingo imenyesha ahanini imitekerereze itatu yo gukoresha PCB yarangiye.

01

PCB yarangiye irashobora gutera hejuru ya pad okiside
Okidation ya PADS igurisha izatera abagurisha nabi, ishobora kuzaga kunanirwa gukora cyangwa ibyago byo guta ishuri. Ubuvuzi butandukanye bwimbaho ​​zumuzunguruko bizaba bifite ingaruka zitandukanye zo kurwanya oki-okiside. Ihame, Enig irasaba gukoreshwa mumezi 12, mugihe OSP isaba gukoreshwa mugihe cyamezi atandatu. Birasabwa gukurikiza ubuzima bwa filf bwuruganda rwa PCB (Shelflife) kugirango ireme ubuziranenge.

Ububiko bwa OSP burashobora koherezwa mu ruganda rw'ubuyobozi kugirango woze Filime ya OSP kandi wongere ukoreshe uruganda rushya kugira ngo rusange uruganda rw'Inama y'Ubutegetsi kugira ngo bagaragaze ko ari firime ya OSP ishobora gusubirwamo.

Imbeba ya ENIG ntishobora gusubirwamo. Muri rusange birasabwa gukora "kanda-guteka" hanyuma ugerageze niba hari ikibazo cyibasiwe.

02

PCB yarangiye irashobora gukuramo ubushuhe kandi itera ikibaho

Ikibaho cyumuzunguruko gishobora guteza ingaruka za popcorn, guturika cyangwa gucibwa mugihe inama yumuzunguruko ihanze nyuma yo gukuraho burundu. Nubwo iki kibazo gishobora gukemurwa no guteka, ntabwo ari inama yubutaka bwose ikwiriye guteka, kandi guteka bishobora gutera ibindi bibazo byiza.

Muri rusange, Inama y'Ubutegetsi oSP ntabwo isabwa guteka, kuko guteka ubushyuhe bwinshi bizangiza film ya esp, ariko abantu bamwe babonaga abantu bafata imigati, ariko igihe cyo guteka kigomba kuba gito gishoboka, kandi ubushyuhe bugomba kuba burebure cyane. Birakenewe kurangiza itanura ryaka mugihe gito, nibibazo byinshi, bitabaye ibyo, umusirikare Pad uzaba okibi cyangwa ngo bigire ingaruka ku gusudira.

03

Ubushobozi bwo guhuza PCB bwarangiye bwarangiye no kwangirika

Nyuma yinama yumuzunguruko, ubushobozi bwo guhuza ibice hagati yabyo (urwego kuri layer) bizagenda bitesha agaciro cyangwa kwiyongera mugihe cyiyongera, imbaraga zinganda ziri hagati yinama yumuzunguruko zizagenda zigabanuka buhoro buhoro.

Iyo ikigo nkiki cyakorewe ubushyuhe bwinshi mu itanura ryaka, kuko imbaho ​​z'umuzunguruko zigizwe n'ibikoresho bitandukanye byo kwagura mu bushyuhe, mu bikorwa byo kwagura mu bushyuhe no kugahagarikwa, birashobora gutera ubushyuhe no kumeneka. Ibi bizagira ingaruka zikomeye ku kwizerwa no kwizerwa kwizerwa no kwizerwa kwizerwa, kubera ko gucyakira akanama kacumbike bishobora guhungabanya imyaya hagati y'ibice by'umuzunguruko, bikaviramo imiterere y'amashanyarazi. Ibibazo byinshi cyane nibibazo bibi bishobora kubaho, kandi birashoboka cyane gutera caf (micro ngufi) utabizi.

Ikigizi cyo gukoresha PCB zarangiye kiracyari kinini, bityo abashushanya bagomba gukoresha PCB mugihe ntarengwa.
