Kuyerekeza Magawo a Granite vs. Steel mu PCB Punching Application.

 

Pakupanga makina osindikizira (PCB), kulondola komanso kulimba ndikofunikira. Mbali yofunika kwambiri ya ndondomekoyi ndi kusindikiza kwa PCB, ndipo kusankha kwazinthu zamagulu osindikizidwa kungakhudze kwambiri khalidwe la kupanga ndi kuchita bwino. Zida ziwiri zomwe zimagwiritsidwa ntchito pamutuwu ndi granite ndi zitsulo, chilichonse chili ndi ubwino wake ndi zovuta zake.

Zigawo za granite zimadziwika chifukwa chokhazikika komanso kusasunthika kwapadera. Kuchulukana kwa miyala yachilengedwe kumapereka maziko olimba omwe amachepetsa kugwedezeka panthawi yopondaponda, potero kumawonjezera kulondola ndikuchepetsa kuvala kwa zida zopondaponda. Kukhazikika kumeneku kumakhala kopindulitsa makamaka pamapulogalamu othamanga kwambiri, pomwe ngakhale kuyenda pang'ono kungayambitse kusamvetsetsana ndi zolakwika. Kuonjezera apo, granite imagonjetsedwa ndi kuwonjezereka kwa kutentha, kuonetsetsa kuti ikugwira ntchito mosasinthasintha pa kutentha kosiyana, zomwe ndizofunikira kwambiri m'madera omwe kutentha kumadetsa nkhawa.

Zida zachitsulo, kumbali ina, zimakondedwa chifukwa cha mphamvu zawo komanso kulimba. Zigawo zachitsulo ndizochepa kwambiri kuposa granite, zomwe zimawapangitsa kukhala odalirika popanga ma voliyumu apamwamba. Kuphatikiza apo, zida zachitsulo zimatha kupangidwa mosavuta ndikusinthidwa kuti zikwaniritse zofunikira zenizeni, kupereka kusinthasintha kwapangidwe komwe granite singagwirizane. Komabe, zigawo zachitsulo zimakhala ndi dzimbiri komanso dzimbiri, zomwe zingakhale zovuta kwambiri m'malo onyowa kapena owononga mankhwala.

Poyerekeza ntchito ya granite ndi chitsulo kwa PCB sitampu ntchito, chigamulo chomaliza zimadalira zofuna zenizeni za ndondomeko kupanga. Kwa ntchito zomwe kulondola ndi kukhazikika ndizofunikira, granite ikhoza kukhala chisankho chabwino kwambiri. Mosiyana ndi izi, pazinthu zomwe zimafuna kukhazikika komanso kusinthasintha, chitsulo chingakhale chopindulitsa kwambiri. Kumvetsetsa mawonekedwe apadera azinthu zilizonse ndikofunikira kwa opanga omwe akufuna kukulitsa njira zawo zopangira PCB.
