1. ICT nyocha
Oghere a na-ejikarị bụ 1.27mm, 1.91MM, 2.54mm.Usoro a na-ejikarị bụ usoro 100, usoro 75, na usoro 50.A na-eji ha eme ihe maka nnwale sekit n'ịntanetị yana nyocha ọrụ.A na-eji ule ICT na ule FCT ugboro ugboro iji nwalee mbadamba PCB efu.
2. Nchọpụta ngwụcha ugboro abụọ
A na-eji ya maka ule BGA.Ọ dị ntakịrị nke siri ike ma na-achọ ọrụ dị elu.Na mkpokọta, a na-anwale ibe IC ekwentị mkpanaaka, ibe IC laptop, kọmpụta mbadamba na nzikọrịta ozi IC.Dayameta ahụ agịga dị n'etiti 0.25MM na 0.58MM.
3. Gbanwee nyocha
Otu nyocha ngbanwe nwere sekit abụọ nke ugbu a iji jikwaa ọrụ sekit na-emeghe na nke mechiri emechi.
4. Nyocha ugboro ugboro
A na-eji ya anwale akara ngosi dị elu, yana mgbanaka mkpuchi, enwere ike ịnwale ya n'ime 10GHz na 500MHz na-enweghị mgbanaka mkpuchi.
5. Rotary nyocha
The elasticity na-adịkarịghị elu, n'ihi na ya penetrability bụ inherent ike, na ọ na-ejikarị maka PCBA ule nke OSP na-esichara.
