Poari tāngia ara iahiko: whakaahuatanga, ti'araa

Ko te āhuatanga hanganga e ngā te turanga, me te parahi conductors uruhanga, e kua takoto i runga i te tïpako i roto i te puka o ngā wāhanga metallized te poari ara iahiko tāngia. E whakarato ana i te pūhui o huānga taiawhio hiko.

he maha o painga whakaritea ki te nuinga (apa) tāutanga whakamahi taura me waea kua te poari ara iahiko:

• ekeeke High kiato o ngā wāhanga reo irirangi me ratou pūhui, hua i roto i te rahi tino heke me te taimaha;
• te fariiraa i te whakahiko a paruru papa, me ngā āhuatanga iraruke i roto i te huringa hangarau kotahi;
• pūmautanga, repeatability āhuatanga pērā i te puritanga, conductance, hiko;
• tere tiketike, me te haruru wātea i te mate circuitry;
• ātete ki ngā awenga pūkaha me te āhuarangi;
• Waeine me whakakotahitanga o hangarau, me te hoahoa rongoā;
• hahi tika, wae me te pūrere rite he katoa;
• ake processability rite ki te hua o te aunoatanga matatini o ngā mahi huihui, mana me te whakatikatikanga ngā mahi;
• kaha mahi iti, te kohi rauemi me ngā utu.

hoki kua te poari taiawhio tā drawbacks, engari ko ratou rawa he bit: iti maintainability me matatini tiketike o te tāpiri huringa hoahoa.

Ko te āhuatanga o taua kāri ngā te turanga uruhanga, he paninga konganuku, i te mea he tauira o conductors tāngia, Pads whakapā; whakatika me te whakapuru rua.

Whakaritenga e tono ki enei hua GOST

• kia whai i te tae ōrite i runga i te tïpako uruhanga ki kia nukurau kotahi i roto i te hanganga poari taiawhio tāngia, e kore i roto i vesicles ā, piko, inclusions ke, kapiti, tītipi, paihere. Heoi whakaaetia rapirapi kotahi, inclusions whakarewa, tango o ngā tohu neprotravlennogo wahi kotahi, me te whakaatu o te hanganga e kore nei e te huri i te tawhā hiko o te hua, e kore e whakaiti i te tawhiti tīkina i waenganui i te huānga tauira.
• Figure - mārama, ki te mata maheni, kahore opupu, kapiti, tihorenga, wahi taputapu. stains iti rohe, engari e kore e neke atu i te rima ngā ia tapawha decimeter, me te kia āhei e hāngai te toenga o te whanui ara ki te tīkina iti; anganga roa ki ono mitamano me te hohonu o te 25 microns.

Ki te whakapai ake i te mahi te waikura, me te whakapai ake i mata poari solderability pani e te hanganga -hiko kia e kia tonu, kahore tihorenga, pakaru, me te podgarov. Whakatika a me nga tikanga whakapuru rua o roto i runga i te tātuhi. Whakaaetia ki te whai i te ine mahora tautuhi utu piha tika. I roto i te tikanga ki te whakapai ake i te tika o te whakapiringa i runga i papa i roto katoa o whakapuru rua te maputia e apa parahi, tona matotoru kia kia iti iho i te 25 microns. huaina ana tēnei tukanga ko - metallization o rua.

He aha te mea akomanga PCB? I raro i titau tenei ariā akomanga pū papa ahumahi haaati, kua whakaratohia ratou e GOST 23751-86. Tei runga i te kiato tauira o te poari taiawhio tāngia e rima akomanga o te tika, i whakaritea te pai rawa o nei i te taputapu hangarau o te taumata hinonga. E kore e nga akomanga tuatahi, me te tuarua rapu taputapu pū, me te e whakaaro cheap ki te whakaputa. Ko te akomanga wha me te rima rapua e rauemi motuhake, taputapu motuhake, mâ tino i roto i te hanga whakaurunga, whāhauhau, whakahaere i te pāmahana. hinonga kāinga papatipu whakaputa papa taiawhio tāngia o te toru o nga piha o te tika.
