He rerekē te hanganga taketake o ngā rau e rua ki ngā āhuahira matua.
Ko ngā āhuatanga matua: Ko te wera o te aluminum me te FR-4 e whakatauritetia ana ki te parenga wera o te iti: ko te aluminum he pūtake, ā, he whakawhitinga te FR-4. Nā te rerekē o te wera o te pūtake, he rerekē te raraunga whakamātautau mō te pikinga pāmahana.
Mahinga:
Mai i te whakatauritetanga o te Pcb Aluminum me te FR-4 pcb, nā te kaha o te wera o te iti konganuku, ka tino pai ake ngā waea, e whakaatu ana i ngā āhuatanga wera tiketike o te Aluminum mai i tētahi atu tirohanga. E pā ana te wera o te Aluminum ki te mātotoru o tōna apa me te whanonga wera. Ko te mea angiangi i te apa whakaroto, ko te teitei ake o te whanonga wera(engari ko te whakahekenga o te parenga ngaohiko).
Āheingatanga:
He kaha pūkaha ake te kaha pūkaha me te uaua o Aluminum, he pai ake i te FR-4.So ka taea te hanga i ngā papa tā nui ki runga i ngā papa iti o Aluminum, e taea ai te whakatū i ngā wae nui.
Whakangungu hiko:
Hei whakarite i te mahinga o te arawhiti, me pare ētahi wae i roto i ngā hua hiko i te māwhitiwhiti me te whakararurarutanga o ngā ngaru autō ā-hiko. Ka taea te whakamahi i te Aluminum hai whakangungu i nga ngaru autō ā-hiko.
Taurea whakanui wera:
Nā te whakawhānuitanga wera o FR-4, ā, ko te mātotoru o te papa, ka pāngia te kounga o ngā puare konganuku me ngā waea. Ko te take matua ko te whakawhānuitanga wera o te kapa i roto i nga rawa taketake ko te 17106cm/cm-C, ā, ko te rau FR-4 ko te 110106cm/cm-C, he nui te rerekētanga, ā, he ngāwari noa iho te whakanui i te whakawhānuitanga me te huri waea kapa me te pānga whakaheke o te rua konganuku i runga i te whaikikotanga hua. Ko te taurea whakanui wera o te Aluminum ko te 50×106cm/cm-C, he iti iho i tērā o te papa FR-4 noa iho, ā, e tata ana ki te taurea whakawhānui wera o te pepa kapa. Mā tēnei e āwhina ki te whakarite i te kounga me te whaikikotanga o te papa arawhiti tā.
He rerekē te arawhiti taupānga, he rerekē te āpure taupānga, e tika ana te papa FR-4 mō te ara iahiko ahuwhānui me ngā hua hiko ahuwhānui.
