Hand Soldering FPC Boards: Malangizo Ofunika ndi Zoganizira

yambitsani

Posonkhanitsa matabwa a flexible printed circuit (FPC), kuwotcha kwa manja ndi njira yogwiritsidwa ntchito kwambiri chifukwa cha kulondola kwake komanso kutsika mtengo.Komabe, pali zinthu zingapo zofunika kuziganizira kuti mukwaniritse kulumikizana kwabwino kwa solder.Mu positi iyi blog, tikambirana mfundo zazikulu zimene tiyenera kulabadira pamene dzanja soldering FPC matabwa dera, kuphatikizapo njira kukhudzana pakati pa soldering chitsulo nsonga ndi chigawo chimodzi, njira kotunga wa soldering waya, nthawi soldering ndi kutentha. zoikamo, etc. Monga kusamala kofunikira kuonetsetsa kuti njira yowotcherera yopanda cholakwika.Tiyeni tilowe!

1. Njira yolumikizirana pakati pa nsonga yachitsulo cha soldering ndi magawo awiri omwe amawotcherera

Kupeza kugwirizana kwakukulu pakati pa chitsulo chosungunuka ndi chigawocho n'kofunika kwambiri kuti pakhale njira yabwino yopangira soldering.Chonde tcherani khutu ku mfundo zotsatirazi:

I. Sungani nsonga yachitsulo chosungunulira mwaukhondo ndi m'mikutidwa:Musanayambe ntchito ya soldering, onetsetsani kuti nsonga yachitsulo cha soldering ndi yoyera komanso yotsekedwa bwino.Izi zimateteza kutentha kwabwinoko ndikuletsa makutidwe ndi okosijeni, zomwe zimapangitsa kuti mafupa azikhala osalala.

2. Ikani ngodya yakumanja:sungani ngodya yoyenera pakati pa nsonga yachitsulo cholumikizira ndi bolodi la FPC.Moyenera, ngodya yovomerezeka ili pakati pa 30 ndi 45 madigiri.Izi zimathandizira kutengera kutentha koyenera ndikupewa kutenthedwa kapena kuwononga zigawo.

3. Ikani mphamvu zokwanira:Ikani kupanikizika pang'ono kwa chigawocho kuti mugulitsidwe, ndikuonetsetsa kuti musagwiritse ntchito mphamvu zambiri chifukwa izi zingayambitse kuwonongeka.Izi zimathandiza kuonetsetsa kulumikizana kolondola komanso kokhazikika pakati pa nsonga yachitsulo cholumikizira ndi bolodi la FPC.

2. Njira yowotcherera mawaya

Momwe waya wowotcherera amagawira zimathandizira kwambiri kuti pakhale kulumikizana koyenera.Chonde tsatirani malangizo awa:

I. Gwiritsani ntchito kuchuluka koyenera kwa solder:Pewani kugwiritsa ntchito solder kwambiri chifukwa zingayambitse kutsekeka kapena kufupika.Mosiyana ndi zimenezo, solder yosakwanira ingayambitse kusagwirizana.Choncho, ndalama zolondola ziyenera kugwiritsidwa ntchito potengera kukula ndi zovuta za mgwirizano wa solder.

2. Sankhani waya wapamwamba kwambiri:Nthawi zonse gwiritsani ntchito waya wogulitsira wapamwamba kwambiri woyenera kuwotcherera bolodi la FPC.Ubwino wa waya wa solder umakhudza kwambiri zotsatira za soldering.

3. Ikani waya wowotcherera mbali ina:Kuti muwonetsetse kutentha koyenera, chonde ikani waya wowotcherera mbali ina ya cholumikizira cha solder.Tekinoloje iyi imalola solder kuyenda momasuka ndikupanga mgwirizano wamphamvu pakati pa zigawo.

3. Kuwotcherera nthawi ndi zokonda kutentha

Nthawi yolondola ya soldering ndi makonzedwe a kutentha ndizofunikira kwambiri kuti tipeze malumikizano odalirika a soldering.Ganizirani mbali zotsatirazi:

I. Dziwani kutentha koyenera:Dzidziwitseni ndi kutentha kovomerezeka kwa ma board a FPC.Nthawi zambiri, kutentha kwapakati pa 250 mpaka 300 madigiri Celsius ndi koyenera.Komabe, ndikofunikira kutsatira malangizo apadera operekedwa ndi wopanga kuti apewe kuwonongeka kwa zinthu zosakhwima.

2. Yang'anirani bwino nthawi yotentha:nthawi yotentha singakhale yaifupi kapena yayitali kwambiri.Kutentha kwanthawi yayitali kumatha kuwononga chigawocho, pomwe kutentha kosakwanira kungayambitse mafupa ofooka a solder.Yesetsani kuchita bwino kwambiri potsatira nthawi yotentha yomwe yatchulidwa.

4. Kuteteza kuwotcherera

Pofuna kupewa zovuta zomwe zingachitike panthawi yowotcherera, njira zodzitetezera ziyenera kuchitidwa.Phatikizani malangizo awa:

I. Onetsetsani mpweya wokwanira:Gwirani ntchito pamalo olowera mpweya wabwino kuti musapume muzinthu zovulaza zomwe zimatulutsidwa panthawi yowotcherera.

2. Tsatirani njira zopewera ESD:Ma board a FPC amatha kutenga electrostatic discharge (ESD).Gwiritsani ntchito mateti oteteza ESD, zingwe zapamanja, ndi njira zina zoyenera kupewa kuwonongeka koyambitsidwa ndi ESD.

3. Pewani kutentha kwambiri:Osawotchera zinthu zina kapena malo enaake panthawi yowotcherera, apo ayi zitha kuwonongeka.Sungani njira yokhazikika komanso yoyendetsedwa kuti mupewe mavuto okhudzana ndi kutentha kwambiri.

Pomaliza

Mukamagwira ntchito ndi ma board ozungulira a FPC, njira zoyenera zolumikizirana ndi manja ndizofunikira kuti zitsimikizire kulumikizana kodalirika komanso kolimba.Mwa kutchera khutu ku njira zolumikizirana, ma waya, nthawi ndi kutentha, komanso kutsatira njira zodzitetezera, mutha kupeza zotsatira zowotcherera bwino.Ndikuchita komanso kusamala mwatsatanetsatane, mutha kudziwa bwino luso lofunikirali pakupanga zamagetsi, zomwe zimapangitsa kuti pakhale ma board apamwamba kwambiri a FPC.
