Ewebata:

bọọdụ sekit e biri ebi na-agbanwe agbanwe (PCBs) agbanweela ụlọ ọrụ eletrọnịkị site n'ịkwalite atụmatụ kọmpat na mgbanwe. Ha na-enye ọtụtụ uru karịa ndị ibe ha siri ike, dị ka njikwa okpomọkụ dị elu, belata ibu na nha, yana ntụkwasị obi ka mma. Otú ọ dị, mgbe ọ na-abịakwute nchịkọta PCB na-agbanwe agbanwe nke 2-layer, ntinye nke ihe siri ike na-aghọ ihe dị egwu.Na blọọgụ a, anyị ga-elebakwu anya na ihe kpatara nchịkọta PCB na-agbanwe agbanwe nke 2-layer chọrọ ihe siri ike ma kparịta mkpa ha dị n'ịhụ na arụmọrụ kacha mma na ogologo ndụ.

Mụta maka nchịkọta PCB na-agbanwe agbanwe:

Tupu anyị abanye n'ime mkpa nke stiffeners, anyị kwesịrị ibu ụzọ nwee nghọta doro anya nke ihe nhazi PCB na-agbanwe agbanwe bụ. Ndobere PCB na-agbanwe agbanwe na-ezo aka na nhazi nke ọtụtụ ọkwa n'ime bọọdụ sekit na-agbanwe agbanwe. N'ime nchịkọta 2-layer, PCB na-agbanwe agbanwe nwere akwa ọla kọpa abụọ kewapụrụ site na ihe mkpuchi na-agbanwe agbanwe (na-abụkarị polyimide).

Kedu ihe kpatara nchịkọta PCB nke nwere akwa abụọ na-agbanwe agbanwe ji chọọ ihe siri ike?

1. Nkwado igwe:

Otu n'ime isi ihe mere eji chọ stiffeners na PCB stackup 2-layer na-agbanwe agbanwe bụ inye nkwado igwe. N'adịghị ka PCB ndị siri ike, PCB ndị na-agbanwe agbanwe enweghị isi ike. Ịgbakwunye stiffeners na-enyere aka iwusi usoro ahụ ike ma na-egbochi PCB ịgbada ma ọ bụ ịgbagha n'oge njikwa ma ọ bụ mgbakọ. Nke a na-adị mkpa karịsịa mgbe PCB ndị na-agbanwe agbanwe na-ehulata ma ọ bụ na-apịaji.

2. kwalite nkwụsi ike:

Ribs na-arụ ọrụ dị mkpa n'ịkwalite nkwụsi ike nke nchịkọta PCB na-agbanwe agbanwe nke 2-layer. Site n'inye PCB siri ike, ha na-enyere aka belata ohere nke nsogbu ndị na-akpata ịma jijiji, dị ka resonance, nke nwere ike imetụta arụmọrụ zuru oke na ntụkwasị obi nke sekit. Na mgbakwunye, ndị stiffeners na-enye ohere maka nhazi na ndebanye aha ka mma n'oge mgbakọ, na-ahụ maka nhazi nke ọma nke components na njikọ njikọ.

3. Nkwado akụrụngwa:

Ihe ọzọ dị mkpa mere 2-layer flex PCB stackups chọrọ ihe siri ike bụ inye nkwado maka akụrụngwa. Ọtụtụ ngwaọrụ eletrọnịkị chọrọ ka akụrụngwa na-ebuli elu elu (SMT) na PCB ndị na-agbanwe agbanwe. Ọnụnọ nke stiffeners na-enyere aka igbasa nrụgide n'ibu na-akpata n'oge a na-ere ere, na-egbochi mmebi nke ihe ndị dị na ya ma hụ na nhazi ha ziri ezi na mkpụrụ na-agbanwe agbanwe.

4. Nchedo site na ihe gbasara gburugburu ebe obibi:

A na-ejikarị PCB na-agbanwe agbanwe na ngwa ekpughere na ọnọdụ gburugburu ebe obibi siri ike, dị ka oke okpomọkụ, iru mmiri, ma ọ bụ mkpughe kemịkalụ. Ọgịrịga ahụ na-arụ ọrụ dị ka ihe mgbochi nchebe, na-echebe sekit ndị dị nro site na mmebi nke ihe ndị a gburugburu ebe obibi kpatara. Na mgbakwunye, ha na-enyere aka melite PCB na-agbanwe agbanwe n'ozuzu nguzogide nrụgide n'ibu ma gbochie ịbanye mmiri, si otú ahụ na-abawanye ogologo ndụ na ntụkwasị obi ya.

5. Iguzosi ike n'ezi ihe na mgbama:

N'ime ngwugwu PCB flex 2-layer, akara na akara ike na-agbakarị na oyi akwa dị n'ime nke bọọdụ flex. Ọgịrịga ahụ dị ugbu a iji dobe oghere kwesịrị ekwesị ma gbochie ndabichi eletrik n'etiti akwa ọla kọpa dị n'ime. Na mgbakwunye, ndị stiffeners na-echebe akara mgbaama dị elu nke nwere mmetụta siri ike site na okwu mkparịta ụka na nhụsianya mgbaama, na-eme ka mgbochi a na-achịkwa na n'ikpeazụ na-edobe iguzosi ike n'ezi ihe mgbama sekit.

Na ngwụcha:

Na nchịkọta, stiffeners bụ akụkụ dị mkpa na nchịkọta PCB 2-layer na-agbanwe agbanwe ka ha na-ekere òkè n'inye nkwado ígwè ọrụ, ịkwalite nkwụsi ike, inye nkwado akụrụngwa, na ichebe ihe ndị metụtara gburugburu ebe obibi.Ha na-echebe sekit ziri ezi, na-edobe iguzosi ike n'ezi ihe mgbaàmà, na-ekwe ka mgbakọ na-aga nke ọma na ịrụ ọrụ a pụrụ ịdabere na ya n'ọtụtụ ngwa. Site n'itinye stiffeners n'ime atụmatụ PCB na-agbanwe agbanwe, ndị injinia nwere ike hụ na ike na ogologo ndụ nke ngwaọrụ eletrọnịkị ha ka na-enweta uru nke sekit na-agbanwe agbanwe.
