PCB Ngwakọta Igwe Dị Elu nke 8 | Rogers RO4350B + Shengyi S1000-2M | RF Circuit Board8

Ngwọta Mmepụta PCB dị elu

Dịka ọkachamara n'ịrụpụta PCB ugboro ugboro, anyị na-enye ọtụtụ ngwọta PCB dị elu nke ahaziri maka ọtụtụ ngwa ugboro ugboro dị iche iche.

Ngalaba Ngwaahịa Anyị Bụ Isi::

✅ PCBs nke nwere ọtụtụ ugboro ngwakọ (Rogers + FR4, Shengyi, wdg)

✅ Igwe eji esi nri na igwe eji esi nri na igwe eji esi nri (5G communication, radar, satellites)

✅ PCBs Njikọta Njupụta Dị Elu (HDI)

✅ PCBs Metal Core (dabere na Aluminom, dabere na Copper)

✅ PCBs TG dị elu (TG170, TG180, wdg)

✅ PCB ndị na-agbanwe agbanwe ma sie ike

Nkewa Ihe Rogers

Rogers Corporation na-enye ọrụ dị iche iche ihe dị elu ugboro ugborodakọtara maka ngwa dị iche iche:

Usoro RO4000 (RO4350B, RO4003C) - Mfu dị ala, nhazi dị mfe, dị mma maka nkwukọrịta ikuku.

Usoro RT/duroid (RT5880, RT6002) – Mfu dị oke ala, nke e mere maka radar na satịlaịtị.

Usoro TMM - Ngwa RF dị elu nwere ike dielectric kwụsiri ike.

Usoro CLTE - Antenna dị oke mma nke nwere ezigbo nkwụsi ike okpomọkụ.

Q1. Gịnị mere PCBs nke nwere ọtụtụ ugboro dị iche iche ji dị mma?

PCB ngwakọ na-ejikọta ihe RF dị ka Rogers RO4350B na FR4, na-ahazi arụmọrụ ọnụ ahịa na arụmọrụ ugboro ugboro dị elu ebe ọ na-eme ka njikwa okpomọkụ na nkwụsi ike igwe dịkwuo mma.

Q2. Gịnị mere e ji eji ígwè blind vias eme ihe na RF PCBs?

Vias ndị na-ekpuchi ihe mgbochi na-ebelata mgbagọ mgbaàmà, na-ebelata ikike parasitic, ma na-eme ka ụzọ dị elu dịkwuo mma, dị mkpa maka ngwa ngwa microwave na RF.

Q3. Kedu uru dị na mkpuchi ọnụ ọlaedo na PCB RF?

Mkpuchi ọla edo na-eme ka nchekwa EMI ka mma, na-eme ka njikwa dịkwuo mma, ma na-egbochi oxidation, na-eme ka arụmọrụ ogologo oge a pụrụ ịtụkwasị obi.

Q4. Kedu ka dielectric constant (Dk) si emetụta imewe RF PCB?

Dk kwụsiri ike na-eme ka mgbasa nke mgbaàmà na-aga n'ihu. Rogers RO4350B, yana Dk = 3.48, na-enye obere mgbanwe usoro na arụmọrụ RF a na-atụ anya ya.

Q5. Ọrụ dị aṅaa ka impedance a na-achịkwa na-arụ na PCBs RF?

Mgbochi a na-achịkwa na-ejigide iguzosi ike n'ezi ihe mgbaàmà, na-ebelata ntụgharị uche, ọ dịkwa oke mkpa maka nnyefe RF dị elu.

Q6. Kedu ihe ndị na-akpata mfu ntinye na PCB ugboro ugboro dị elu?

Mbelata ntinye na-adabere na oke ike nke elu ọla kọpa, ihe Df (mfu dielectric), nhazi PCB, na geometry conductor.

Q7. Kedu ihe bụ isi ihe dị mkpa maka imewe PCB ugboro ugboro?

Belata ogologo akara iji gbochie mbelata

Jiri foil ọla kọpa dị nro belata mfu mgbaàmà

Mee ka nchịkọta dịkwuo mma maka njikwa impedance

Zere ịgbagọ agbagọ iji nọgide na-enwe iguzosi ike n'ezi ihe nke akara

Q8. Kedu ka njikwa okpomọkụ si emetụta arụmọrụ RF PCB?

Iji ihe dị elu (TG170) na vias okpomọkụ na-eme ka okpomọkụ dị mma, na-eme ka ogologo ndụ PCB na arụmọrụ kwụsie ike.

Q9. Kedu ihe dị iche n'etiti Rogers RO4000 na RT/duroid laminates?

Usoro RO4000 (RO4350B, RO4003C): Dị ọnụ ala, ọ dabara adaba maka mmepụta oke nke PCB RF.

Usoro RT/duroid (RT5880, RT6002): Ihe ndị dị oke mma nwere obere mfu dielectric, dị mma maka ngwa RF dị elu.

Q10. Ị na-enye ngwọta ODM na OEM ahaziri iche maka PCB RF?

Ee! Anyị bụ ọkachamara n'ịmepụta PCB RF pụrụ iche, nhọrọ ihe, nhazi mkpokọta, na mmepụta ihe atụ maka ngwa RF ahaziri ahazi.
