Na pcb imewe, anyị na-echekarị ma a ga-eji ọla kọpa kpuchie elu pcb? Nke a na-adabere n'ezie na ọnọdụ ahụ, nke mbụ anyị kwesịrị ịghọta uru na ọghọm dị n'elu ọla kọpa.

Mbụ ka anyị leba anya na uru mkpuchi ọla kọpa:

1. N'elu ọla kọpa nwere ike inye nchebe nchebe ọzọ na mkpọtụ mkpọtụ maka mgbaàmà n'ime;
2. Nwere ike melite ikike mkpofu ọkụ nke pcb
3. Na PCB mmepụta usoro, chekwaa ego nke corrosive gị n'ụlọnga;
4. Zere PCB warping deformation kpatara PCB n'elu reflow nchegbu kpatara ahaghị nhata ọla kọpa foil.

Ihe mkpuchi elu nke ọla kọpa kwekọrọ na ya nwekwara ọghọm ndị kwekọrọ:

1, A ga-ekewapụ ụgbọ elu nke ọla kọpa nke dị n'èzí site na ihe ndị dị n'elu na ahịrị mgbama gbajiri, ma ọ bụrụ na enwere mpempe ọla kọpa na-adịghị mma (karịsịa nke ahụ dị ogologo ogologo ọla kọpa), ọ ga-aghọ antenna, na-ebute nsogbu EMI;

Maka ụdị akpụkpọ anụ ọla kọpa a anyị nwekwara ike igwu site na ọrụ nke ngwanrọ

2.Ọ bụrụ na a na-eji ọla kọpa kpuchie ihe mejupụtara pin ahụ ma jikọta ya nke ọma, ọ ga-eme ka ọ ghara ikpo ọkụ ngwa ngwa, na-akpata ihe isi ike na ịgbado ọkụ na ịgbado ọkụ, n'ihi ya, anyị na-ejikarị usoro ntinye ọla kọpa nke njikọ cross maka ihe nkedo.

Ya mere, nyocha nke ma a na-ekpuchi elu ya na ọla kọpa nwere nkwubi okwu ndị a:

1, PCB imewe maka okpukpu abụọ nke osisi, mkpuchi ọla kọpa dị ezigbo mkpa, n'ozuzu na ala ala, elu oyi akwa nke isi ngwaọrụ ma na-eje ije akara ike na akara mgbaàmà.
2, n'ihi na elu impedance circuit, analọg circuit (analog-na-dijitalụ mgbanwe circuit, ịgbanwee mode ike ọkọnọ mgbanwe circuit), ọla kọpa mkpuchi bụ ezigbo omume.
3.For multi-layer board high-speed digital circuits na zuru ezu ike ọkọnọ na ala ụgbọ elu, mara na nke a na-ezo aka elu-ọsọ dijitalụ sekit, na ọla kọpa mkpuchi na elu oyi akwa agaghị eweta oké uru.
4.N'ihi na ojiji nke multi-layer osisi digital circuit, n'ime oyi akwa nwere a zuru ezu ike ọkọnọ, ala ụgbọ elu, ọla kọpa mkpuchi n'elu enweghị ike budata ibelata crosstalk, ma dị nso na ọla kọpa ga-agbanwe impedance nke microstrip nnyefe akara, discontinuous ọla kọpa ga-emekwa ka a ọjọọ mmetụta na nnyefe akara impedance kwụsị.
5.N'ihi na mbadamba multilayer, ebe ebe dị anya n'etiti eriri microstrip na ụgbọ elu ntụaka bụ <10mil, a na-ahọrọ ụzọ nlọghachi nke mgbaàmà ahụ kpọmkwem na ụgbọ elu ntụaka dị n'okpuru akara ngosi, karịa mpempe ọla kọpa gbara ya gburugburu, n'ihi nkwụsị ala ya. Maka efere okpukpu abụọ nwere anya nke 60mil n'etiti ahịrị mgbama na ụgbọ elu ntụaka, ihe mkpuchi ọla kọpa zuru oke n'akụkụ ụzọ akara ngosi niile nwere ike belata mkpọtụ.
6.For multi-layer mbadamba, ma ọ bụrụ na e nwere ihe elu ngwaọrụ na wiring, adịghị etinye ọla kọpa iji zere oke agbaji ọla kọpa. Ọ bụrụ na elu components na elu-ọsọ akara bụ obere, na osisi bụ dịtụ efu, iji PCB nhazi chọrọ, ị nwere ike họrọ dina ọla kọpa n'elu, ma ntị na PCB imewe n'etiti ọla kọpa na elu-ọsọ akara akara dịkarịa ala 4W ma ọ bụ karịa, iji zere ịgbanwe àgwà impedance nke mgbaàmà akara.
