Ubwino wa Granite Inspection Plates pa Kutsimikizira Ubwino wa PCB.

 

Mu dziko la kupanga zamagetsi, makamaka popanga ma printed circuit board (PCBs), kutsimikizira khalidwe ndikofunikira kwambiri. Chimodzi mwa zida zothandiza kwambiri pakutsimikizira kulondola ndi kulondola pakupanga ma PCB ndikugwiritsa ntchito ma granite inspection boards. Malo olimba komanso okhazikika awa amapereka maubwino osiyanasiyana omwe amawonjezera njira yotsimikizira khalidwe.

Choyamba, mbale zowunikira granite zimapereka kusalala bwino komanso kulimba. Kapangidwe kachilengedwe ka granite kamapangitsa kuti pamwamba pake pasakhale pathyathyathya kwambiri, komanso kuti pasakhale kupotoka ndi kusinthika pakapita nthawi. Kukhazikika kumeneku ndikofunikira kwambiri poyesa ma PCB, chifukwa ngakhale zolakwika zazing'ono zingayambitse zolakwika zazikulu pakupanga. Pogwiritsa ntchito mbale za granite, opanga amatha kuwonetsetsa kuti miyeso yawo ndi yolondola, zomwe zimapangitsa kuti pakhale zinthu zabwino kwambiri.

Kuphatikiza apo, ma granite board owunikira ndi olimba kwambiri komanso osawonongeka. Mosiyana ndi zipangizo zina zomwe zingawonongeke kapena kuwonongeka pakapita nthawi, granite imasunga umphumphu wake, kupereka yankho lokhalitsa kuti zitsimikizire khalidwe. Kulimba kumeneku kumatanthauza kuti ndalama zochepa zokonzera komanso kusasintha pafupipafupi, zomwe zimapangitsa kuti ma granite board akhale chisankho chotsika mtengo kwa opanga ma PCB.

Ubwino wina waukulu wa ma granite test plates ndi wogwirizana ndi zida zosiyanasiyana zoyezera. Kaya mukugwiritsa ntchito ma caliper, ma micrometer kapena makina oyezera ogwirizana (CMMs), ma granite plates amatha kukhala ndi zida zosiyanasiyana, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito mosiyanasiyana pakutsimikizira khalidwe. Kusinthasintha kumeneku kumathandiza opanga kukonza njira zawo zoyezera ndikuwonjezera magwiridwe antchito onse.

Pomaliza, ubwino wa ma granite board owunikira kuti PCB ikhale yabwino ndi womveka bwino. Kusalala kwawo, kulimba, komanso kugwirizana kwawo ndi zida zoyezera kumawapangitsa kukhala chuma chamtengo wapatali kumakampani opanga zamagetsi. Mwa kuyika ndalama m'ma granite board owunikira, opanga amatha kupititsa patsogolo njira zawo zotsimikizira khalidwe, pomaliza pake kupanga zinthu zabwino za PCB ndikukweza kukhutitsidwa kwa makasitomala.
