Mafotokozedwe Akatundu

Etchant (etchant) imagwiritsidwa ntchito kwambiri popanga zitsulo, kupanga semiconductor, kupanga zida zamagetsi, kupanga chip ndi kafukufuku wasayansi. Pokonza zitsulo, ma etchants amagwiritsidwa ntchito kuchotsa ma oxides kapena zinthu zosafunikira pamalo achitsulo, potero amawongolera mawonekedwe ndi mawonekedwe azitsulo. Popanga semiconductor ndi zamagetsi, etchants amagwiritsidwa ntchito kupanga tinthu tating'onoting'ono ndi mabwalo. Pankhani ya kafukufuku wa sayansi, ma etchants angagwiritsidwe ntchito pokonzekera zitsanzo kuti awone mawonekedwe awo. Mwachidule, ma etchants ali ndi ntchito zofunika m'magawo ambiri.

Popanga semiconductor, Etchant ndi yankho lamankhwala lomwe limagwiritsidwa ntchito popanga tchipisi ndi zida zina za semiconductor. Etching iyi imagwiritsidwa ntchito popanga tinthu tating'onoting'ono monga ma tchanelo ndi ma vias omwe amatanthawuza kuzungulira kwa chip ndi zina. Nthawi zambiri, Etchant imagwiritsidwa ntchito kumadera ena a chipangizo cha semiconductor, kudzera muukadaulo wa masking kapena njira zina, kuti akwaniritse mawonekedwe ndi mapangidwe omwe mukufuna. Kuzama ndi kulondola kwa etching kumatha kusinthidwa ndikuwongolera kapangidwe ka Etchant, kutentha ndi nthawi yolumikizira. Chifukwa chake, popanga semiconductor, Etchant ndi njira yofunikira yomwe imagwiritsidwa ntchito pofotokozera ndikupanga mapangidwe abwino pa chip.

Etchant (etchant) nthawi zambiri amagwiritsidwa ntchito pokonza ma boarder osindikizidwa (PCBs) panthawi yopanga zida zamagetsi, makamaka popanga ma chemical etching. Ntchito yake ndikuchotsa magawo osafunika omwe amaphimba pamwamba pa zojambulazo zamkuwa kuti apange dongosolo loyenera la dera. Masitepe ogwiritsira ntchito ndi awa: Konzani dongosolo la dera lomwe mukufuna ndikusamutsira ku zojambula zamkuwa. Ikirani PCB mu Etchant, yomwe imachotsa zojambula zamkuwa zokha zosatetezedwa, ndikusiya mawonekedwe ozungulira omwe mukufuna. Yang'anirani nthawi yowotchera kuti muwonetsetse kuti chojambula chamkuwa chokhacho chimachotsedwa. Mwanjira iyi, Etchant ikhoza kuthandizira kupanga mayendedwe ofunikira, gawo lofunikira kwambiri pakupanga kwa PCB.
