Gịnị bụ wafer warpage?

Waferwarpage na-ezo aka na-ehulata ma ọ bụ ntụgharị nke wafer n'oge usoro nkwakọ ngwaahịa.Waferwarpage nwere ike ibute ndakpọ n'usoro, nsogbu ịgbado ọkụ na mmebi arụmọrụ ngwaọrụ n'oge usoro nkwakọ ngwaahịa.

Ebelatala izi ezi nkwakọ ngwaahịa:Waferwarpage nwere ike ibute ndakpọ n'oge usoro nkwakọ ngwaahịa. Mgbe wafer ahụ na-agbanwe n'oge usoro nkwakọ ngwaahịa, enwere ike imetụta nhazi n'etiti mgbawa na ngwaọrụ ngwugwu, na-ebute enweghị ike ịkwado ntụtụ njikọ ma ọ bụ nkwonkwo solder. Nke a na-ebelata izi ezi nkwakọ ngwaahịa ma nwee ike ibute ịrụ ọrụ ngwaọrụ enweghị ntụkwasị obi ma ọ bụ enweghị ntụkwasị obi.

Mgbakasị igwe na-abawanye:Waferwarpage na-ewebata nrụgide n'ibu ọzọ. N'ihi nrụrụ nke wafer n'onwe ya, nrụgide ọrụ nke etinyere n'oge usoro nkwakọ ngwaahịa nwere ike ịba ụba. Nke a nwere ike bute mgbakasị uche n'ime wafer, metuta ihe na nhazi ngwaọrụ ahụ nke ọma, na-ebute mmebi nke ime wafer ma ọ bụ ọdịda ngwaọrụ. 

Mmebi arụmọrụ:Ibe wafer nwere ike bute mmebi arụmọrụ ngwaọrụ. A na-emepụta ihe ndị na-emepụta ihe na nhazi sekit na wafer na-adabere n'elu ala dị larịị. Ọ bụrụ na wafer na-agba, ọ nwere ike imetụta njikọ eletriki, nnyefe mgbaàmà na njikwa okpomọkụ n'etiti ngwaọrụ. Nke a nwere ike ịkpata nsogbu na arụmọrụ eletriki, ọsọ, oriri ike ma ọ bụ ntụkwasị obi nke ngwaọrụ.

Nsogbu ịgbado ọkụ:Wafer warpage nwere ike ịkpata nsogbu ịgbado ọkụ. N'oge usoro ịgbado ọkụ, ma ọ bụrụ na wafer na-ehulata ma ọ bụ gbagọrọ agbagọ, ikesa ike n'oge usoro ịgbado ọkụ nwere ike ịbụ nke na-adịghị mma, na-akpata adịghị mma nke nkwonkwo na-agbado ma ọ bụ ọbụna na-agbaji nkwonkwo.
