He tikanga whai hua te tākai taumata wafer whakawātea (FOWLP) i roto i te umanga haurua-ā-ira. Engari ko ngā pānga taha noa o tēnei tukanga ko te piko me te wehewehe maramara. Ahakoa te whakapai tonu o te hangarau whakawātea taumata wafer me te taumata panera, kei te mau tonu ēnei take e pā ana ki te whakahāngai.
Ko te piko o te kiriuhi ka puta mai i te whakahekenga matū o te matū whakakikorua wai (LCM) i te wā e whakamaroke ana, e whakamatao ana hoki i muri i te whakakikorua. Ko te take tuarua o te piko ko te kore taurite o te tauwehenga wera (CTE) i waenga i te maramara silicon, te rauemi whakakikorua, me te papa. Ko te take o te whakawehenga ko ngā rauemi whakakikorua matotoru he nui te ihirangi whakakī ka taea anake te whakamahi i raro i te pāmahana teitei me te pēhanga teitei. I te mea ka piri te maramara ki te kawe mā te hononga rangitahi, ka whakangawari te piripiri i te pāmahana teitei, ka ngoikore te kaha o te piripiri, ka whakaiti hoki i tōna kaha ki te whakapiri i te maramara. Ko te take tuarua o te whakawehenga ko te pēhanga e hiahiatia ana mō te whakakikorua ka hanga he ahotea ki runga i ia maramara.
Hei kimi i ngā otinga mō ēnei wero, i whakahaerehia e DELO tētahi rangahau whaihua mā te here i tētahi maramara anaro māmā ki tētahi kaikawe. Mō te whakatakotoranga, ka pania te papa kawe ki te piripiri here rangitahi, ā, ka whakatakotoria te maramara ki raro. Muri iho, ka hangaia te papa kawe mā te whakamahi i te piripiri DELO matotoru iti, ā, ka whakamaroketia ki te hihi ultraviolet i mua i te tango i te papa kawe. I roto i ēnei tono, ka whakamahia ngā whakakotahitanga whakakikorua whakamahana matotoru teitei.
I whakaritea hoki e DELO te piko o ngā rauemi whakahāngai werawera me ngā hua kua whakamaroketia ki te UV i roto i te whakamātautau, ā, i whakaatuhia e ngā hua ka piko ngā rauemi whakahāngai noa i te wā whakamatao i muri i te whakahāngai werawera. Nō reira, mā te whakamahi i te whakamaroketia ki te pāmahana rūma hei utu mō te whakamahana ka taea te whakaiti i te pānga o te kore taurite o te tauwehenga whānui wera i waenga i te matū whakahāngai me te kaikawe, ā, mā reira ka whakaitihia te piko ki te taumata nui rawa atu.
Mā te whakamahinga o ngā rauemi whakamaroke ultraviolet ka taea hoki te whakaiti i te whakamahinga o ngā whakakī, ā, ka whakaitihia te matotoru me te modulus a Young. Ko te matotoru o te tauira piripiri i whakamahia i te whakamātautau he 35000 mPa · s, ā, ko te modulus a Young he 1 GPa. Nā te kore o te wera, te pēhanga nui rānei i runga i te rauemi whakahāngai, ka taea te whakaiti i te rerekētanga maramara ki te taumata teitei rawa atu. Ko te matotoru o tētahi matū whakahāngai noa he tata ki te 800000 mPa · s, ā, ko te modulus a Young kei roto i te awhe o ngā mati e rua.
I te nuinga o te wā, kua whakaatuhia e ngā rangahau he pai te whakamahi i ngā rauemi kua whakamaroketia ki te UV mō te hanga i te takai taumata-rahi, me te whakaiti i te piko me te rerekētanga o te maramara ki te taumata nui rawa atu. Ahakoa ngā rerekētanga nui o ngā tauwehenga whānui wera i waenga i ngā rauemi e whakamahia ana, he maha tonu ngā whakamahinga o tēnei tukanga nā te kore o te rerekētanga pāmahana. Hei tāpiri, ka taea hoki e te whakamaroketia ki te UV te whakaiti i te wā whakamaroketia me te whakapaunga pūngao.
Ka whakaitihia e te UV hei utu mō te whakamaroke wera te piko me te nekehanga mate i roto i te takai taumata-waferi pā-waho
Te whakataurite i ngā anga papatahi 12-inihi te whānui mā te whakamahi i tētahi matū whakakī-teitei kua whakamaroketia e te wera (A) me tētahi matū kua whakamaroketia e te UV (B)
