Akamaro ka Stiffeners muri 2-Layeri Yoroshye PCB Stackup

Intangiriro:

Ikibaho cyoroshye cyandika cyumuzunguruko (PCBs) cyahinduye inganda za elegitoronike mu gukora ibishushanyo mbonera kandi byoroshye. Batanga inyungu nyinshi kurenza bagenzi babo bakomeye, nko gucunga neza ubushyuhe, kugabanya uburemere nubunini, no kurushaho kwizerwa. Ariko, iyo bigeze kuri 2-layer flexible PCB stack-ups, gushyiramo stiffeners biba ingirakamaro.Muri iyi blog, tuzareba neza impamvu ibice 2 byoroshye PCB yibitseho bisaba gukomera no kuganira ku kamaro kabo mugukora neza no kuramba.

Wige ibijyanye na PCB yoroheje:

Mbere yo gucukumbura akamaro ko gukomera, dukeneye mbere na mbere gusobanukirwa neza icyo PCB ihinduka. Imiterere ihindagurika ya PCB bivuga gahunda yihariye yuburyo bwinshi muburyo bworoshye bwumuzunguruko. Mubice 2 byububiko, PCB ihindagurika igizwe nibice bibiri byumuringa bitandukanijwe nibikoresho byoroshye (mubisanzwe polyimide).

Kuberiki ikeneye ibice 2 byoroshye PCB ikenera gukomera?

1. Inkunga ya mashini:

Imwe mumpamvu nyamukuru zituma stiffeners ikenerwa murwego rwa 2 rworoshye PCB stackup nugutanga inkunga yubukanishi. Bitandukanye na PCB zikomeye, PCB zoroshye zidafite ubukana bwihariye. Ongeramo stiffeners ifasha gushimangira imiterere kandi ikabuza PCB kunama cyangwa gutitira mugihe cyo gukora cyangwa guterana. Ibi biba ngombwa cyane cyane mugihe PCB zoroshye zunamye cyangwa zizingamye.

2. Kongera umutekano:

Urubavu rufite uruhare runini mukuzamura ituze rya 2-layer PCB yoroheje. Mugutanga ubukana kuri PCB, bafasha kugabanya amahirwe yibibazo biterwa no kunyeganyega, nka resonance, bishobora kugira ingaruka mbi kumikorere rusange no kwizerwa kwizunguruka. Byongeye kandi, stiffeners yemerera guhuza neza no kwiyandikisha mugihe cyo guterana, byemeza neza neza ibice hamwe nibisobanuro bihuza.

3. Inkunga yibigize:

Indi mpamvu yingenzi ituma ibice 2 bya flex PCB isaba gukomera ni ugutanga inkunga kubice. Ibikoresho byinshi bya elegitoronike bisaba tekinoroji yubuso (SMT) kugirango bishyirwe kuri PCB yoroheje. Kubaho kwa stiffeners bifasha gukwirakwiza imihangayiko ikoreshwa mugihe cyo kugurisha, kurinda ibyangiritse kubice byuzuye no kwemeza guhuza neza na substrate yoroheje.

4. Kurinda ibintu bidukikije:

PCB ihindagurika ikoreshwa kenshi mubisabwa guhura n’ibidukikije bikaze, nkubushyuhe bukabije, ubushuhe, cyangwa imiti y’imiti. Urubavu rukora nk'inzitizi ikingira, irinda imiyoboro yoroheje ibyangiritse bishobora guterwa nibi bidukikije. Byongeye kandi, bifasha kunoza uburyo bworoshye PCB irwanya ihungabana ryimashini no kwirinda kwinjiza amazi, bityo bikongerera kuramba no kwizerwa.

5. Inzira nyabagendwa n'ubunyangamugayo:

Mubice 2 bya flex PCB yibitseho, ibimenyetso hamwe nimbaraga zumurongo mubisanzwe bikorera kumurongo wimbere wibibaho bya flex. Urubavu rurahari kugirango rugumane umwanya ukwiye kandi wirinde guhuza amashanyarazi hagati yumuringa w'imbere. Byongeye kandi, ibyuma bikingira birinda ibimenyetso byihuta byerekana ibimenyetso byihuta byambukiranya umuhanda no kwerekanwa ibimenyetso, bikabuza inzitizi zagenzuwe kandi amaherezo bikagumana ubuziranenge bwibimenyetso byumuzunguruko.

Mu gusoza:

Muncamake, stiffeners nibintu byingenzi mubice 2 byoroshye PCB yibitseho kuko bigira uruhare mugutanga ubufasha bwimashini, kuzamura umutekano, gutanga inkunga yibigize, no kurinda ibidukikije.Zirinda inzitizi zuzuye, zigumana ubuziranenge bwibimenyetso, kandi zemerera guterana neza no gukora neza mubikorwa bitandukanye. Mugushyiramo stiffeners muburyo bworoshye bwa PCB, injeniyeri zirashobora kwemeza gukomera no kuramba kwibikoresho byabo bya elegitoronike mugihe bishimira ibyiza byumuzunguruko.
