Kusamala popanga ndi kusungirako mizere yowunikira ya LED ndi mizere yowunikira

Njira zodzitetezera pakupanga ndi kusungirako mizere yowunikira ya LED ndi mizere yowunikira Panthawi yopanga chingwe cha LED, padzakhala chodabwitsa cha imfa yabodza ya LED (ndiko kuti, kuwala kwa LED sikuyatsa). Zifukwa za chodabwitsa ichi ndi motere: 1. Magetsi osasunthika amawotcha 1: 1 Chifukwa LED ndi gawo lodziwika bwino la electrostatic, ngati chitetezo cha electrostatic sichinachitike bwino panthawi yopanga, chipangizo cha LED chidzatenthedwa chifukwa cha magetsi osasunthika, zomwe zidzachititsa imfa yabodza ya mzere wa LED. 1: 2 Muyeso wopewa izi ndikulimbitsa chitetezo chamagetsi. Ogwira ntchito onse omwe amakhudza ma LED ayenera kuvala magolovesi odana ndi static ndi mphete zosasunthika motsatira malamulo, ndipo zida ndi zida ziyenera kukhala pansi. 2. Kuwonongeka kwakukulu kwa kutentha Kutentha kwapamwamba kwa 2: 1 LED sikwabwino. Choncho, ngati kutentha kwa kuwotcherera ndi nthawi yowotcherera ya LED sikuyendetsedwa bwino panthawi yopangira ndi kukonza, chipangizo cha LED chidzawonongeka chifukwa cha kutentha kwakukulu kapena kutentha kosalekeza, zomwe zimapangitsa kuti LED ikhale yochititsa chidwi ya kuyimitsidwa kwa makanema ojambula.

2: 2 Njira zopewera izi ndi: gwirani ntchito yabwino pakuwongolera kutentha kwa reflow soldering ndi soldering iron, gwiritsani ntchito munthu wapadera yemwe ali ndi udindo, komanso kasamalidwe ka mafayilo apadera; chitsulo chosungunula chimagwiritsa ntchito chitsulo chowongolera kutentha kuti chiteteze bwino kutentha kwachitsulo chachitsulo kuti chisawotche chipangizo cha LED. 3. Chinyezi chimaphulika pa kutentha kwakukulu 3: 1 Ngati phukusi la LED likuwonekera mlengalenga kwa nthawi yaitali, limatenga chinyezi. Ngati sichikuwonongeka musanagwiritse ntchito, chinyezi mu phukusi la LED chidzakhudzidwa ndi kutentha kwakukulu komanso nthawi yayitali panthawi ya reflow soldering. Kuwonjezeka kwa kutentha kumapangitsa phukusi la LED kuphulika, zomwe zimapangitsa kuti chipangizo cha LED chitenthe kwambiri ndikuwonongeka. 3: 2 Yankho: Malo osungiramo ma LED amayenera kusungidwa kutentha ndi chinyezi nthawi zonse. Ma LED osagwiritsidwa ntchito ayenera kuphikidwa mu uvuni pafupifupi 80 ° kwa maola 6-8 kuti awononge chinyezi musanagwiritse ntchito, kuti atsimikizire kuti ma LED omwe amagwiritsidwa ntchito ndi ofanana. Sipadzakhala kuyamwa chinyezi.
