The mgbọrọgwụ nke mbili na ọdịda kpebisiri ike site àgwà nke ihe onwunwe. Iji dozie nsogbu nke shrinkage nke isiike-Mgbanwe PCB Board , ka anyị a nkenke iwebata ka ihe onwunwe nke na-agbanwe efere Polyimide:
(1) polyimide nwere magburu onwe thermal arụmọrụ, nwere ike idi ihe kwes ujo nke-edu ndú-free soldering okpomọkụ omume;
(2) Ọtụtụ ngwaọrụ emepụta agbasaghị iji mgbanwe na sekit na sekit osisi maka obere ngwaọrụ na mkpa ka mesie mgbaàmà ike n'ezi;
(3) Polyimide nwere nnukwu iko mgbanwe okpomọkụ ma na elu agbaze mgbe e ji mara,

(4) Na organic mgbasa, polyimide bụ unyi anaghị agbasa na nkịtị organic solvents.
Mgbanwe efere ihe na ala na isi isi ihe onwunwe PI na mama nwere a mmekọrịta, nke ahụ bụ, a oké mmekọrịta imidation nke PI, na elu ogo imidization, ndị siri ike na controllability.
Dị ka nkịtị mmepụta iwu, mgbe mgbanwe osisi ọnwụ, na guzobe nke ndịna akara, na Nchikota isiike na juu na usoro nke mkpakọ ga nwere mgbanwe degrees nke ibu na mkpi na ndịna akara etching, akara osisi ike na direction , ga-eduga ná reorientation nke nchegbu nke dum osisi, na-emecha na-eduga general ụkpụrụ nke osisi na ala mgbanwe; na usoro nke na ijikọta na juu na ike, dị ka elu ekpuchi film na isi ihe onwunwe PI mgbasa ọnụọgụ ekwekọghị, N'ime akporo a ụfọdụ ruo n'ókè nke mgbasa.
