ʻO ka mīkini etching laser, ka mea e hōʻike ana i ka etching pololei me ka wikiwiki kiʻekiʻe, ʻo ia ka mīkini hana ʻike maʻamau i nā ʻoihana hana PCB. Akā hoʻokahi mea hiki ʻole i kēia mau hui ke hala - S&ʻO kahi ʻāpana chiller portable Teyu CW-3000.
Pili ka PCB i ka papa kaapuni paʻi a he ʻāpana koʻikoʻi ia o nā mea uila. Inā ʻoe e nānā kokoke, nui nā huaʻōlelo liʻiliʻi ma ka PCB. No ka hoʻopuka ʻana i nā huaʻōlelo liʻiliʻi ma luna o ia mau papa liʻiliʻi, pono ia i ka ʻenehana etching pololei loa. No laila, ʻo ka mīkini etching laser, e hōʻike ana i ka etching pololei me ka wikiwiki kiʻekiʻe, ʻo ia ka mīkini hana ʻike maʻamau i nā ʻoihana hana PCB.
