A na-egbutu oghere ọkara nke metallized na ọkara mgbe agbachara oghere ahụ.Ọ dị mfe ịpụta ihe ngosi nke ihe fọdụrụ na waya ọla kọpa na akpụkpọ anụ akpụkpọ anụ na-agba na ọkara oghere, nke na-emetụta ọrụ nke oghere ọkara ma na-eduga n'ibelata arụmọrụ ngwaahịa na mkpụrụ.Iji merie ntụpọ ndị a dị n'elu, a ga-eme ya dị ka usoro ndị a si dị na PCB nke metallized semi-orifice:

1. Nhazi ọkara oghere abụọ V ụdị mma.

2. N'okwu nke abụọ, a na-agbakwunye oghere nduzi na nsọtụ oghere ahụ, a na-ewepụ akpụkpọ ahụ ọla kọpa n'ihu, na-ebelata burr.A na-eji oghere ndị ahụ eme ihe maka mkpọpu mmiri iji kwalite ọsọ nke ọdịda.

3. Ihe mkpuchi ọla kọpa na mkpụrụ, nke mere na akwa akwa ọla kọpa na mgbidi oghere nke oghere gburugburu na nsọtụ efere ahụ.

4. A na-eme sekit nke dị n'èzí site na fim mkpakọ, ikpughe na mmepe nke mkpụrụ n'aka n'aka, mgbe ahụ, a na-etinye mkpụrụ osisi ahụ na ọla kọpa na tin ugboro abụọ, nke mere na oyi akwa ọla kọpa na mgbidi oghere nke oghere gburugburu na nsọtụ. a na-agbaji efere na akwa ọla kọpa na-ekpuchi akwa tin nwere mmetụta mgbochi corrosion;

5. Ọkara oghere na-akpụ efere nsọtụ gburugburu oghere bee na ọkara na-etolite ọkara oghere;

6. Iwepụ ihe nkiri ahụ ga-ewepụ ihe nkiri na-egbochi ihe nkiri a na-agbanye na usoro ịpị ihe nkiri;

7. Etch nke mkpụrụ ahụ, ma wepụ ihe mkpuchi ọla kọpa ekpughere na oyi akwa nke mpụta ahụ mgbe o wepụsịrị ihe nkiri ahụ; mgbidi gbawara agbawa na-ekpughe.

9. Mgbe akwa ọla kọpa nke abụọ na tin na-etinye na mkpụrụ, a na-egbutu oghere okirikiri dị na nsọtụ efere ahụ na ọkara iji mepụta oghere ọkara.N'ihi na akwa ọla kọpa nke mgbidi oghere ahụ na-eji akwa tin kpuchie, na akwa ọla kọpa nke mgbidi oghere ahụ na-ejikọta ya na akwa ọla kọpa nke mpụta nke mkpụrụ ahụ, na ike na-ejikọta ya bụ nnukwu, akwa ọla kọpa na oghere ahụ. enwere ike ịzere mgbidi nke ọma mgbe ị na-egbutu ya, dị ka ịdọpụ ma ọ bụ ihe ngosi nke ịgbatị ọla kọpa;

10. Mgbe ẹkụre ọkara oghere akpụ wee wepụ ihe nkiri, na mgbe etch, ọla kọpa elu oxidation agaghị eme, n'ụzọ dị irè zere omume nke ọla kọpa fọdụrụnụ na ọbụna obere sekit onu, melite mkpụrụ metallized ọkara oghere PCB. .
