Pali mitundu yambiri yama board ozungulira pamsika, ndipo mawu aukadaulo ndi osiyana, omwe gulu la fpc limagwiritsidwa ntchito kwambiri, koma anthu ambiri sadziwa zambiri za bolodi la fpc, ndiye fpc board imatanthauza chiyani?

1, fpc bolodi amatchedwanso "kusintha dera bolodi", ndi imodzi mwa PCB kusindikizidwa dera bolodi, ndi mtundu wa ntchito insulating zakuthupi monga gawo lapansi, monga: polyimide kapena poliyesitala filimu, ndiyeno mwa njira yapadera anapanga. ya bolodi yosindikizidwa. Kachulukidwe wama waya a bolodi laderali nthawi zambiri amakhala okwera, koma kulemera kwake kumakhala kopepuka, makulidwe ake amakhala ochepa thupi, komanso amakhala ndi magwiridwe antchito abwino, komanso magwiridwe antchito abwino.

2, fpc board ndi PCB board ndizosiyana kwambiri. Gawo laling'ono la bolodi la fpc nthawi zambiri limakhala la PI, chifukwa chake limatha kupindika, kusinthasintha, ndi zina zambiri, pomwe gawolo la bolodi la PCB nthawi zambiri limakhala FR4, kotero silingapindike mopanda pake komanso kusinthasintha. Chifukwa chake, kugwiritsa ntchito ndikugwiritsa ntchito kwa fpc board ndi PCB board ndizosiyana kwambiri.

3, chifukwa bolodi la fpc likhoza kupindika ndi kusinthasintha, bolodi la fpc limagwiritsidwa ntchito kwambiri pamalo omwe amafunika kusinthasintha mobwerezabwereza kapena kugwirizana pakati pa magawo ang'onoang'ono. The PCB bolodi ndi okhwima, choncho chimagwiritsidwa ntchito m'madera ena kumene safunika kupindika ndi mphamvu ndi zovuta.

4, fpc bolodi ali ndi ubwino ang'onoang'ono kukula, kuwala kuwala, kotero akhoza mogwira kuchepetsa kukula kwa zinthu zamagetsi ndi laling'ono kwambiri, choncho chimagwiritsidwa ntchito makampani mafoni makampani, makampani TV, makampani digito kamera ndi zina. makampani ang'onoang'ono, otsogola kwambiri azinthu zamagetsi.

5, bolodi la fpc silingangopindika momasuka, komanso limatha kuvulazidwa mwachisawawa kapena kupindidwa pamodzi, komanso kukonzedwa momasuka molingana ndi zosowa za malo. Mu malo atatu-dimensional, bolodi la fpc lingathenso kusuntha mosasamala kapena kuwonera telescope, kotero kuti cholinga chogwirizanitsa chikhoza kutheka pakati pa waya ndi msonkhano wachigawo.

Kodi mafilimu owuma a PCB ndi chiyani?

1, PCB ya mbali imodzi

Pansi mbale amapangidwa ndi pepala phenol mkuwa laminated bolodi (pepa phenol monga maziko, yokutidwa ndi zojambulazo mkuwa) ndi pepala Epoxy mkuwa laminated bolodi. Ambiri aiwo amagwiritsidwa ntchito pazinthu zamagetsi zapakhomo monga mawayilesi, zida za AV, ma heaters, mafiriji, makina ochapira, ndi makina ogulitsa monga osindikiza, makina ogulitsa, makina ozungulira, ndi zida zamagetsi.

2, PCB yokhala ndi mbali ziwiri

Zida zoyambira ndi Glass-Epoxy copper laminated board, GlassComposite copper laminated board, ndi pepala Epoxy copper laminated board. Ambiri aiwo amagwiritsidwa ntchito pamakompyuta apakompyuta, Zida zamagetsi zamagetsi, matelefoni amitundu yambiri, makina amagetsi apagalimoto, zotumphukira zamagetsi, zoseweretsa zamagetsi, ndi zina. Ponena za Glass benzene resin copper laminated laminates, Glass polima laminated laminated laminates amagwiritsidwa ntchito kwambiri pamakina olankhulirana. , makina osindikizira a satellite, ndi makina olankhulana ndi mafoni chifukwa cha makhalidwe awo apamwamba kwambiri, ndipo ndithudi, mtengo wake ndi wokwera.

3, 3-4 zigawo za PCB

Zomwe zimayambira ndi Glass-Epoxy kapena benzene resin. Amagwiritsidwa ntchito makamaka pamakompyuta amunthu, makina a Me (zamagetsi azachipatala, zamagetsi azachipatala), makina oyezera, makina oyesera a semiconductor, makina a NC (NumericControl, kuwongolera manambala) makina, zosinthira zamagetsi, makina olumikizirana, ma board ozungulira kukumbukira, makhadi a IC, ndi zina zambiri. komanso galasi kupanga mkuwa laminated bolodi monga Mipikisano wosanjikiza zipangizo PCB, makamaka kuganizira kwambiri makhalidwe ake processing.

4,6-8 zigawo za PCB

Zoyambira zimatengera GLASS-epoxy kapena Glass benzene resin. Amagwiritsidwa ntchito posinthira zamagetsi, makina oyesera a semiconductor, makompyuta apakatikati, EWS (EngineeringWorkStation), NC ndi makina ena.

5, zigawo zoposa 10 za PCB

Gawoli limapangidwa makamaka ndi utomoni wa Glass benzene, kapena GLASS-epoxy ngati gawo la magawo angapo a PCB. Kugwiritsa ntchito kwa mtundu uwu wa PCB ndikwapadera kwambiri, ambiri mwa iwo ndi makompyuta akuluakulu, makompyuta othamanga kwambiri, makina olankhulana, etc., makamaka chifukwa ali ndi makhalidwe apamwamba komanso kutentha kwambiri.

6, zina za PCB gawo lapansi

Zida zina za gawo lapansi za PCB ndi gawo lapansi la aluminiyamu, gawo lapansi lachitsulo ndi zina zotero. Deralo limapangidwa pa gawo lapansi, lomwe limagwiritsidwa ntchito kwambiri pamagalimoto (motor yaing'ono). Komanso, pali kusintha PCB (FlexiblPrintCircuitBoard), dera aumbike pa polima, poliyesitala ndi zipangizo zina zazikulu, angagwiritsidwe ntchito ngati wosanjikiza umodzi, wosanjikiza awiri, kuti Mipikisano wosanjikiza bolodi kungakhale. Izi kusintha bolodi dera zimagwiritsa ntchito mbali zosunthika makamera, OA makina, etc., ndi kugwirizana pakati pa PCB olimba kapena ogwira kugwirizana kugwirizana pakati pa PCB zolimba ndi PCB zofewa, monga kugwirizana kugwirizana njira chifukwa mkulu elasticity, mawonekedwe ake ndi osiyanasiyana.

Mipikisano wosanjikiza board ndi sing'anga ndi mkulu TG mbale

Choyamba, matabwa ozungulira a PCB amitundu yambiri amagwiritsidwa ntchito m'malo otani?

Multilayer PCB matabwa dera zambiri ntchito zipangizo kulankhulana, zipangizo zachipatala, ulamuliro mafakitale, chitetezo, zamagetsi galimoto, ndege, kompyuta zotumphukira minda; Monga "chizindikiro chachikulu" m'magawo awa, ndi kuwonjezeka kosalekeza kwa ntchito zamalonda, mizere yowonjezereka yowonjezereka, zofunikira za msika za khalidwe la bolodi zikuchulukirachulukira, ndipo kufunikira kwamakasitomala kwapakati ndi kwakukulu. Ma board ozungulira a TG akuchulukirachulukira.

Chachiwiri, makamaka a Mipikisano wosanjikiza matabwa PCB dera

Wamba PCB bolodi adzakhala ndi mapindikidwe ndi mavuto ena pa kutentha kwambiri, pamene makina ndi makhalidwe magetsi mwinanso kutsika kwambiri, kuchepetsa moyo utumiki wa mankhwala. Munda wa ntchito Mipikisano wosanjikiza bolodi PCB zambiri ili mu makampani mkulu-mapeto luso, amene mwachindunji amafuna kuti bolodi ndi bata mkulu, kukana mkulu mankhwala, ndipo akhoza kupirira kutentha, chinyezi mkulu ndi zina zotero.

Chifukwa chake, kupanga ma board a PCB amitundu ingapo kumagwiritsa ntchito mbale zosachepera TG150, kuwonetsetsa kuti bolodi ladera likuchepetsedwa ndi zinthu zakunja pakugwiritsira ntchito ndikuwonjezera moyo wautumiki wa mankhwalawa.

Chachitatu, kukhazikika kwamtundu wa TG wapamwamba komanso kudalirika kwakukulu

Mtengo wa TG ndi chiyani?

Mtengo wa TG: TG ndi kutentha kwapamwamba kwambiri komwe pepalalo limakhala lolimba, ndipo mtengo wa TG umatanthawuza kutentha kumene polima amorphous (komanso gawo la amorphous la crystalline polima) amasintha kuchokera ku galasi kupita kumalo okwera kwambiri (rabala). dziko).

Mtengo wa TG ndi kutentha kofunikira komwe gawo lapansi limasungunuka kuchoka ku cholimba kupita kumadzimadzi a rubbery.

Mulingo wa mtengo wa TG umagwirizana mwachindunji ndi kukhazikika ndi kudalirika kwa zinthu za PCB, ndipo kuchuluka kwa TG kwa bolodi kumapangitsa kukhazikika komanso kudalirika.

High TG sheet ili ndi zotsatirazi:

1) Kukana kutentha kwakukulu, komwe kumatha kuchepetsa kuyandama kwa mapadi a PCB panthawi yosungunuka yotentha ya infuraredi, kuwotcherera ndi kugwedezeka kwamafuta.

2) Low matenthedwe coefficient (otsika CTE) akhoza kuchepetsa warping chifukwa cha kutentha zinthu, ndi kuchepetsa mkuwa kuthyoka pa ngodya ya dzenje chifukwa matenthedwe kukula, makamaka PCB matabwa ndi zigawo eyiti kapena kuposa, ntchito ya yokutidwa ndi mabowo. ndiyabwino kuposa ma board a PCB okhala ndi TG wamba.

3) Imakhala ndi kukana kwamankhwala kwabwino kwambiri, kotero kuti bolodi la PCB litha kuviikidwa munjira yonyowa komanso mayankho ambiri amankhwala, magwiridwe ake akadali osasunthika.
