Chekutanga tichatsanangura nezvenyaya yedu, ndiko kuti, kukosha kwePCB dhizaini kune iyo SMT chigamba maitiro.Maererano nezvinyorwa zvatakaongorora kare, tinogona kuona kuti dzakawanda zvehutano hwehutano mu SMT dzakabatana zvakananga nezvinetso zvekugadzirisa mberi.Zvakangofanana nepfungwa ye "deformation zone" yatinoisa pamberi nhasi.
Izvi zvinonyanya kuitirwa PCB.Chero bedzi iyo yepasi pePCB yakakotama kana isina kuenzana, iyo PCB inogona kunge yakakotama panguva yekuisa screw maitiro.Kana mashoma akateedzana screws akagovaniswa mumutsara kana padyo nenzvimbo imwechete yekutsvagisa, iyo PCB ichakotama nekuremara nekuda kwekudzokororwa chiito chekushushikana panguva yekutonga kweiyo screw yekuisa maitiro.Isu tinodaidza iyi yakapetwa yakakotama nzvimbo yedeformation zone.
Kana iyo chip capacitors, BGAs, modules, uye mamwe ettress shanduko yekuchinja akaiswa munzvimbo yedeformation panguva yekuiswa, ipapo solder joint inogona kusatsemuka kana kutyoka.
Kutyoka kweiyo module magetsi ekupa solder yakabatana mune iyi kesi ndeyemamiriro ezvinhu aya
(1) Regedza kuisa zvinonetsa-sensitive components munzvimbo dziri nyore kukotama nekuremara panguva yegungano rePCB.
(2) Shandisa iyo yepasi bracket tooling panguva yegungano kuita kuti PCB iparadze iyo screw inoisirwa kudzivirira kukotama kwePCB panguva yekuungana.
(3) Simbisa majoini ekutengesa.
