Ndi iti yomwe ili yoyenera kwambiri pakukonza msonkhano wa PCB pakati pa kuwotcherera kosankha ndi kuwotcherera kozungulira?

Chowotcherera chosankhidwa ndi ma wave soldering amagwiritsidwa ntchito kwambiriKutsimikizira kwa PCB.Komabe, iliyonse mwa njirazi ili ndi ubwino wake ndi kuipa kwake.Tiyeni tiwone zowotcherera zosankhidwa ndi kuwotcherera mafunde - ndi iti yomwe ili yoyenera kwambiri pokonza chip cha SMT, kutsimikizira ndi kusonkhanitsa?

 

Wave soldering

Kutentha kwa mafunde, komwe kumadziwikanso kuti reflow soldering, kumachitika mumlengalenga woteteza mpweya, chifukwa zimadziwika kuti kugwiritsa ntchito nayitrogeni kumatha kuchepetsa kwambiri kuthekera kwa kuwonongeka kwa kuwotcherera.

 

Njira yopangira ma wave soldering imaphatikizapo:

1. Ikani chovala cha flux kuyeretsa ndi kukonzekera msonkhano.Izi ndizofunikira chifukwa zonyansa zilizonse zidzakhudza njira yowotcherera.

2. Circuit board preheating.Idzayambitsa kusinthasintha ndikuwonetsetsa kuti bolodi silikugwedezeka ndi kutentha.

3. PCB imadutsa mu solder yosungunuka.Pamene bolodi la dera likuyenda pa njanji yowongolera njanji, kugwirizana kwa magetsi kumakhazikitsidwa pakati pa zida zamagetsi, zikhomo za PCB ndi solder.

Wave soldering ndiyothandiza kwambiri pakupanga zinthu zambiri, koma ilinso ndi zovuta zake, makamaka kuphatikiza:

1. Kugwiritsa ntchito solder ndikokwera kwambiri

2. imadya kusinthasintha kwambiri

3. Wave soldering amagwiritsa ntchito mphamvu zambiri

4. Kudya kwake kwa nayitrogeni ndikokwera

5. Kuwotchera kwa mafunde kumafunika kukonzedwanso pambuyo pa soldering yoweyula

6. Pamafunikanso kuyeretsa yoweyula soldering dzenje thireyi ndi kuwotcherera zigawo zikuluzikulu

7. Mwachidule, mtengo wa soldering wave ndi wokwera kwambiri, ndipo mtengo wogwiritsira ntchito umatengedwa kuti ndi pafupifupi kasanu kuposa kuwotcherera kosankha.

Kuwotcherera kosankha

Kuwotchera kosankhidwa ndi mtundu wa ma wave soldering, omwe amagwiritsidwa ntchito kukweza zida zopangira za SMT zophatikizidwa ndi zida zapabowo.Selective wave soldering imatha kupanga zinthu zazing'ono komanso zopepuka.

Kusankha kuwotcherera kumaphatikizapo:

Kugwiritsa ntchito flux pazigawo zomwe ziyenera kuwotcherera / board board preheating / solder nozzle pazowotcherera zigawo zinazake.

 

Ubwino wa kusankha kuwotcherera:

1. Flux imagwiritsidwa ntchito kwanuko, kotero palibe chifukwa chotetezera zigawo zina

2. Palibe kusinthasintha kofunikira

3. Imakulolani kuti muyike magawo osiyanasiyana pagawo lililonse

4. Palibe chifukwa chogwiritsa ntchito matayala obowola okwera mtengo

5. Itha kugwiritsidwa ntchito pama board ozungulira omwe sangakhale otenthetsera

6. Pazonse, ubwino wake wachindunji kwa makasitomala ndi mtengo wotsika

 

Chifukwa chake, momwe mungasankhire njira yoyenera yopangira msonkhano wa PCB iyenera kuwunikiridwa mozama ndi makasitomala malinga ndi mawonekedwe azinthu.
