Pafupifupi chidutswa chilichonse cha Printed Circuit Board (PCB) chimakhala ndi njira yolembera zinthu. Izi zili choncho chifukwa chidziwitso chomwe chimasindikizidwa pa PCB chimatha kuzindikira ntchito yoyang'anira khalidwe, kuzindikira zokha komanso kutsatsa mtundu wa chinthu. Chidziwitsochi chinkasindikizidwa ndi makina osindikizira achikhalidwe. Koma makina osindikizira achikhalidwe amagwiritsa ntchito zinthu zambiri zomwe zingayambitse kuipitsa chilengedwe mosavuta. Ndipo chidziwitso chomwe amasindikiza chimatha pakapita nthawi, zomwe sizothandiza kwenikweni.
Koma pa makina olembera chizindikiro cha laser, mavuto amenewo salinso mavuto. Makina olembera chizindikiro cha laser ali ndi njira yosakhudzana ndi kukhudzana, liwiro lapamwamba, palibe zinthu zogwiritsidwa ntchito komanso palibe kuipitsidwa. Amatha kulemba zizindikiro zomveka bwino, zolondola komanso zokhalitsa pamtundu wocheperako mpaka 3x3mm. Kupatula apo, popeza alibe kukhudzana mwachindunji, sadzawononga PCB.
Makina odziwika bwino olembera laser a PCB amayendetsedwa ndi laser ya CO2 ndi UV. Pogwiritsa ntchito makina omwewo, makina olembera laser a UV ali ndi kulondola kwakukulu kuposa makina olembera laser a CO2. Kutalika kwa nthawi ya laser ya UV kuli pafupifupi 355nm ndipo zinthu zambiri zimatha kuyamwa bwino kuwala kwa laser ya UV m'malo mwa kuwala kwa infrared. Kuphatikiza apo, laser ya CO2 ndi mtundu wa kukonza kutentha kuti zitsimikizire zotsatira zake. Chifukwa chake, carbonization ndi yosavuta kuchitika, zomwe zimakhala zovulaza kuzinthu zoyambira za PCB. M'malo mwake, laser ya UV ndi "processing yozizira", chifukwa imazindikira zotsatira zake poswa mgwirizano wa mankhwala kudzera mu kuwala kwa laser ya UV. Chifukwa chake, laser ya UV sidzawononga PCB.
Monga tikudziwira, PCB ndi yaying'ono kwambiri ndipo chidziwitso cholembera pa iyo sichophweka. Koma UV laser imatha kuchita izi mwanjira yeniyeni. Izi zimachitika osati chifukwa cha mawonekedwe apadera a makina olembera UV laser komanso makina oziziritsira omwe amabwera nawo. Makina oziziritsira olondola ndi ofunikira kwambiri pakusunga kutentha kwa UV laser kuti UV laser igwire ntchito bwino kwa nthawi yayitali. S&A Teyu compact chiller unit CWUL-05 imagwiritsidwa ntchito kwambiri poziziritsira makina olembera UV laser mu PCB marking. Chiller iyi ili ndi kukhazikika kwa kutentha kwa 0.2℃, zomwe zikutanthauza kuti kusinthasintha kwa kutentha ndi kochepa kwambiri. Ndipo kusinthasintha pang'ono kumatanthauza kuti kutulutsa kwa UV laser kwa laser kudzakhala kokhazikika. Chifukwa chake, zotsatira zolembera zitha kutsimikizika. Kuphatikiza apo, CWUL-05 compact water chiller unit ndi yaying'ono kwambiri, kotero simatenga malo ambiri ndipo imatha kulowa mosavuta mu makina olembera PCB laser.
