Muchokwadi, PCB warping zvakare inoreva zvakare kukotama kwedunhu redunhu, iyo inoreva iyo yekutanga flat wedunhu redunhu. Kana yakaiswa pane desktop, iwo maviri magumo kana pakati pebhodhi anoonekwa zvishoma kumusoro. Ichi chiitiko chinozivikanwa sePCB warping muindasitiri.

Fomula yekuverenga iyo yehondo yedunhu ndeyekuisa dunhu redunhu flat pane tafura ine makona mana eboka redunhu pasi uye kuyera kukwirira kweArch pakati. Fomula iri seinotevera:

Warpage = kureba kweiyo arch / kureba kwePCB refu divi * 100%.

Circuit Board Warpage Industry Standard: Maererano neIPC - 6012 (1996 Edition) "Kufunga kwekucherechedzwa kwekurwadzisa Nekuda kwekugona kwakasiyana kwekugona kwefekitori yega yega, kune zvakare mamwe mutsauko muPCB warpage control zvinodiwa.
