Iyo deformation ye Pcb bhodhi, inozivikanwawo sedhigirii rehondo, ine pesvedzero huru pane welding uye kushandiswa. Kunyanya kune zvigadzirwa zvekutaurirana, bhodhi rimwechete rinoiswa mubhokisi-mubhokisi. Pane chiyero chepakati pakati pemapuranga. Nekupfupika kwepaneru, mukaha pakati pezvikamu zviri padhuze plug-in mabhodhi unova diki uye diki. Kana iyo PCB yakakotama, inozokanganisa plugging uye unplugging, inobata zvikamu. Kune rumwe rutivi, deformation yePCB ine simba guru pakuvimbika kweBGA zvikamu. Naizvozvo, zvakakosha kwazvo kudzora deformation yePCB panguva uye mushure mekutengesa.

(1) Iyo dhigirii ye deformation yePCB yakanangana nehukuru hwayo uye ukobvu. Kazhinji, chikamu chechiyero ishoma pane kana kuenzana ne2, uye hupamhi kusvika kune ukobvu reshiyo ishoma pane kana kuenzana ne150.

(2) Multilayer rigid PCB inoumbwa nemhangura foil, prepreg uye core board. Kuti uderedze deformation mushure mekudzvanya, iyo laminated dhizaini yePCB inofanirwa kuzadzisa symmetrical dhizaini zvinodiwa, kureva, ukobvu hwefoiri yemhangura, rudzi uye ukobvu hwepakati, kugoverwa kwezvinhu zvegraphic (circuit layer, ndege. layer), uye kumanikidzwa kunoenderana nekukora kwePCB. Mutsetse wepakati wegwara unoenzana.

(3) Kune maPCB mahombe, anti-deformation stiffeners kana lining board (anonziwo fire-proof board) anofanira kugadzirwa. Iyi inzira yekusimbisa michina.

(4) Kune zvikamu zvezvimiro zvakaiswa zvishoma zvinogona kukonzera PCB board deformation, senge CPU kadhi sockets, bhodhi rinotsigira rinodzivirira PCB deformation rinofanira kugadzirwa.
