Chipangizocho sichikugwira ntchito mutasintha cholumikizira cha FPC

Kotero mwangosintha Cholumikizira cha Fpc—mwina pafoni yam'manja, laputopu, kamera, kapena chida china chilichonse—ndipo tsopano chipangizocho sichikuyatsa, chinthu china chake chatha, kapena mukuyamba kuchita zinthu zosakhazikika. Zokhumudwitsa, eti? Simuli nokha. Izi zimachitika kawirikawiri kuposa momwe mungaganizire, ndipo nkhani yabwino ndi yakuti nthawi zambiri, vutoli limathetsedwa popanda zida zapadera kapena digiri ya uinjiniya wamagetsi.

Mu bukhuli, ndikufotokozerani zifukwa zomwe chipangizo chanu chimagwirira ntchito pambuyo poti Kusintha cholumikizira cha FPC, ndi momwe tingayambitsirenso kugwira ntchito. Tiyeni tiyambe ndi kufufuza mwachangu poyamba—chifukwa kukonza kungakhale kosavuta kuposa momwe mukuganizira.

Choyamba, musachite mantha (ndipo musamakakamize chilichonse)

Chipangizo chikalephera kugwira ntchito mutangosintha cholumikizira, cholinga chake ndi kukankhira mwamphamvu, kuyikanso chingwe mwamphamvu, kapena kubwerezanso ntchito yonse yosokera. Imani. Kukakamiza zinthu nthawi zambiri kumapinda mapini kapena kung'amba Dera Losindikizidwa Losinthasintha (FPC) yokha. Pumirani mpweya wambiri, yatsani chipangizocho kwathunthu, ndipo tiyeni tipite pang'onopang'ono.

Omwe angakhale olakwa kwambiri

1. Chingwe sichinakhazikike bwino kapena chili mozondoka

Ichi ndi chifukwa #1. Cholumikizira cha FpcZikuoneka zosavuta, koma n'zosavuta kuzilumikiza molakwika. Chingwecho chiyenera kulowa molunjika, mpaka kumbuyo kwa cholumikizira, ndipo chotchingira (ngati chilipo) chiyenera kutsekedwa kwathunthu. Ngakhale kutsekedwa ndi theka la milimita kungasokoneze kulumikizana.

Komanso, yang'anani komwe zinthu zili. Chingwe cha FpcZimawoneka ngati zofanana, koma sizili choncho. Yang'anani chitsanzo cha copper pad, m'mphepete mwake mopingasa, kapena mzere wosindikizidwa womwe umasonyeza mbali yoyenera mmwamba. Ngati mutayiyika kumbuyo, chipangizocho sichingayankhe konse, kapena choipa kwambiri—kuchepetsa china chake.

2. Mapini opindika, okwezedwa, kapena osowa pa cholumikizira chatsopano

Kusintha Cholumikizira cha Fpc Nthawi zambiri zimakhala zomangira zolimba kapena ntchito yotentha. Ngati munagwiritsa ntchito chitsulo chomangira, n'zosavuta kupinda mwangozi pini kapena kulumikiza ziwiri zomwe zili pafupi. Ngakhale zolumikizira zosinthidwa zomwe zapangidwa kale zitha kufika ndi kuwonongeka. Tengani galasi lokulitsira kapena kamera ya foni yanu yolumikizidwa ndikuyang'ana pini iliyonse. Yang'anani:

• Mapini omwe sakugwirizana ndi ena onse
• Milatho yosokera (tinthu tating'onoting'ono tolumikiza mapini awiri)
• Cholumikizira chomwe chimakhala chokhota pang'ono pa bolodi

Ngati muwona chilichonse mwa izi, muyenera kukonzanso malo olumikizirana. Pa ma pini opindika, singano yaying'ono kapena chotsukira mano chingathe kuwawongola pang'onopang'ono—koma chitani pang'onopang'ono.

3. Chingwe cha FPC chinawonongeka panthawi yosintha

Mwina munayang'ana kwambiri pa cholumikizira ndipo sanayang'ane chingwecho. Ma FPC ndi ofooka. Kuwapinda mwamphamvu, kuwakoka, kapena kuwagwira ndi zala zamafuta kungang'ambe madontho kapena kuswa gawo loyendetsa. Yang'anani chingwecho kuti muwone ngati:

• Ming'alu kapena ma nick pafupi ndi mapeto
• Makwinya kapena mikwingwirima
• Zizindikiro za moto (ngati munali ndi chitsulo chosungunula pafupi kwambiri)

Ngati chingwecho chikuoneka ngati chokayikitsa, yesani kusintha ndi china chodziwika bwino ngati n'kotheka. Nthawi zina njira yosavuta yothetsera vutoli ndi kungosintha chingwecho. Chingwe cha Fpc kachiwiri.

4. Mtundu wolakwika wa cholumikizira chosinthira

Si zonse Cholumikizira cha Fpcs amapangidwa mofanana. Ngakhale atakhala ofanana, mtunda (mtunda pakati pa ma pin) ukhoza kukhala 0.5mm vs 0.3mm, kapena njira yotsekera ikhoza kusiyana. Cholakwika chofala: kugwiritsa ntchito cholumikizira cha "top contact" pomwe choyambirira chinali "bottom contact," kapena mosemphanitsa. Izi zikutanthauza kuti ma pad a chingwe sakhudza bwino ma terminal a cholumikizira.

Yang'anani kawiri nambala ya gawo poyerekeza ndi yoyambirira. Ngati mulibe deta, yerekezerani zolumikizira zatsopano ndi zakale mbali ndi mbali pansi pa kuwala kwabwino. Yang'anani kutalika, mawonekedwe a latch, ndi malo a zolumikizira zachitsulo.

5. Zinyalala kapena zotsalira za flux mkati mwa cholumikizira

Pambuyo pothira soldering, flux imatha kulowa mu cholumikizira. Flux nthawi zambiri imakhala yoyendetsa pang'ono kapena yowononga pakapita nthawi. Komanso, tinthu tating'onoting'ono ta soldering, fumbi, kapena tsitsi losochera limatha kukhala pakati pa mapini ndikuyambitsa kabudula kapena kulumikizana kosalekeza.

Tsukani cholumikizira mosamala. Gwiritsani ntchito 99% isopropyl alcohol ndi burashi yofewa (bulashi la mano lakale limagwira ntchito). Kenako liumireni ndi mpweya wozizira. Musagwiritse ntchito thonje lomwe limasiya ulusi. Lolani kuti liume kwathunthu musanalumikizanenso chingwe.

Kuthetsa mavuto pang'onopang'ono (chitani izi motsatira dongosolo)

Gawo 1: Kuyang'ana maso popanda magetsi
Chotsani Chingwe cha Fpc kachiwiri. Yang'anani cholumikizira ndi chingwe pansi pa kuwala kowala ndi kukula. Yang'anani chilichonse chachilendo—mapini opindika, zinyalala, ndi madontho owonongeka.

Gawo 2: Bwezerani chingwecho moyenera
Ikani chingwecho molunjika komanso molunjika. Kankhirani mpaka mutamva kukana pang'ono (chiyenera kutsika pansi). Ngati pali chotchingira chotseka, chitembenuzireni pansi kapena chikankhireni patsogolo mpaka mutamva kapena kumva kudina. Pa zolumikizira zolowetsa (zopanda chotchingira), chingwecho chiyenera kukhala chogwirizana ndi thupi la cholumikizira.

Gawo 3: Yesani ndi zigawo zochepa
Ngati chipangizo chanu chili ndi zambiri Zolumikizira za FPC (monga kuwonetsa, kukhudza, mabatani), chotsani chilichonse kupatulapo zochepa zomwe zimafunika kuti muwone moyo. Pa foni, izi zitha kukhala batire ndi batani lamphamvu la FPC. Izi zimathandiza kupeza cholumikizira chomwe chikuyambitsa vutoli.

Gawo 4: Yang'anani ngati pali kupitirira (ngati muli ndi multimeter)
Ikani multimeter yanu mu continuity mode. Chingwe chitakhala pansi ndikutsekedwa, gwirani probe imodzi ku pad kumapeto kwa chingwe ndi probe inayo ku pini yofanana pa bolodi (kapena malo oyesera pambuyo pa cholumikizira). Muyenera kupeza beep. Chitani izi kwa ma pini angapo osasinthika. Kupanda beep kumatanthauza kulumikizana koyipa mkati mwa cholumikizira kapena trace yosweka.

Gawo 5: Yesani kupanikizika pang'ono mukamayesa
Nthawi zina cholumikizira chimamangirira koma sichigwirana mokwanira. Pamene chipangizocho chikuyaka (mosamala!), kanikizani pang'onopang'ono pamwamba pa cholumikiziracho kapena kankhirani chingwecho ku bolodi. Ngati chipangizocho chikugwira ntchito mwadzidzidzi, mumakhala ndi kulumikizana kofooka kwa makina. Nthawi zina mutha kukonza izi powonjezera shim yopyapyala (monga chidutswa cha tepi ya Kapton) kumbuyo kwa chingwecho kuti muwonjezere mphamvu.

Nthawi yoti musinthe zonse zomwe zasinthidwa

Ngati mwadutsa njira zonse koma chipangizocho sichikugwirabe ntchito, mungakhale ndi vuto lalikulu:

• Pedi yokwezedwa pa PCB– Pedi yamkuwa pomwe zolumikizira zolumikizira zimang'ambika. Izi zimafuna kukonza waya wa jumper.
• Kulunjika kolakwika kwa cholumikizira - Mwasoka cholumikiziracho mwachizunguliza madigiri 180. Inde, zimachitika.
• Kuwonongeka kwa ESD– Kutulutsa kwa electrostatic kumatha kukazinga chip chomwe chimalumikizana ndi FPC. Ngati simunagwiritse ntchito mphasa yokhazikika kapena lamba wa dzanja, izi ndizotheka koma sizodziwika kawirikawiri.

Pazochitikazi, njira yabwino kwambiri ndi kuchotsanso cholumikizira, kutsuka ma pad, ndikuyesera china chatsopano. Ngati simukudzidalira, pitani nacho ku malo okonzera zinthu okhala ndi maikulosikopu ndi malo okonzanso.

Momwe mungapewere izi nthawi ina

• Tengani zithunzi musanajambule - Chotsani zithunzi za cholumikizira choyambirira ndi momwe chingwe chilili musanachotse chilichonse.
• Gwiritsani ntchito kutentha kochepa komanso kusinthasintha - Mukasungunula chitsulo, sungani chitsulocho pa 300-330°C ndipo gwiritsani ntchito kusinthasintha kwabwino. Kutentha kwambiri kumasokoneza thupi la cholumikizira cha pulasitiki.
• Chogwirira Chingwe cha Fpcm'mphepete mwa m'mphepete mwa m'manja mwanu - Mafuta ochokera m'zala zanu amatha kuwononga chophimba cha conductive pakapita nthawi.
• Yesani musanayikenso kwathunthu - Mukasintha cholumikizira, lumikizani batri ndi FPC kuti muwone ngati ntchitoyo ikugwira ntchito. N'zosavuta kwambiri kukonza vutoli chipangizocho chikatsegulidwa.

Maganizo omaliza

Chipangizo chomwe sichikugwira ntchito pambuyo pake Kusintha cholumikizira cha FPC Si chilango cha imfa kwenikweni. Malinga ndi zomwe ndakumana nazo, milandu yoposa 80% imathetsedwa mwa kungoyikanso chingwecho bwino kapena kutsuka pang'ono kutuluka kwa cholumikiziracho. 20% yotsala nthawi zambiri imakhala ndi pini yopindika kapena chingwe chowonongeka.

Tengani nthawi yanu, gwiritsani ntchito kuwala kowala bwino, ndipo musaope kubwereza sitepe. Mwachita kale gawo lovuta—kusintha cholumikizira chokha. Tsopano ndi pafupifupi milimita yomaliza yolumikizira.

Ngati mukukakamirabe, siyani ndemanga pansipa yokhudza chipangizo chanu ndi zomwe mwayesa. Mwina wina wakumanapo ndi zomwezo. Zabwino zonse, ndipo mundidziwitse mukayamba kugwira ntchito!
