Cov lus qhia rau soldering nrog solding hlau: koj yuav tsum tau mloog li cas thaum nrog cov khoom siv hluav taws xob sib txawv?
Soldering ntawm cov cim PAR hom: Siv cov hluav taws xob tshuab hlau thiab cov yas cam rau teev thiab tsim cov khoom siv uas tsim nyog. Thaum soldering array pin Cheebtsam, qhov ntev ntev ntawm cov pins tivthaiv Cov txheej txheem ntawm soldering yog mus ua ntej tso tawm cov cam ntawm cov hlua hlau, thiab tom qab ntawd cov hlau hlau kaw rau cov hlau ruaj ruaj. Yog hais tias tus nqi ntawm solder yog tsim nyog, txav cov hlua hlau tawm ua ntej. Thaum cov hlua khi nyob hauv cov qauv ua haujlwm, txav cov hlau txhaws pov tseg. Nco ntsoov tias nws tsis yog kev xav kom tso ntau dhau ntawm lub ncoo. Thaum kawg, txiav tawm cov pins ntev.
Soldering smt Cheebtsam nrog cov hluav taws kub tshuab: ua ntej, koj tuaj yeem muab cov khoom siv uas ua tau los ua ke, thiab yog tias nws tuaj yeem ua tau los tiv thaiv cov khoom tiv thaiv los ntawm kev ua soldered khov kho txaus). Tom qab ntawd siv cov hluav taws xob tshuab hluav taws xob hlau thiab tweezers txhawm rau txhim kho ib qho kawg ntawm cov khoom ua ntej, thiab tom qab ntawd kos lwm qhov kawg ntawm kev txhim kho cov khoom sib xyaw ua ke. Txhawm rau ua kom cov khoom sib xyaw kom nruj nrog cov Cirtric Board, koj tuaj yeem ua ntej nrog cov hluav taws xob nrog cov roj hluav taws xob rau lwm tus, thiab nias nws nrog cov qauv loj). Nto mount resistor).
When soldering integrated chip type surface mount components, first place a small amount of solder on the solder pads of each pin of the chip, then place the chip on top, determine the position, and fix the diagonal ends of the chip first. Yog tias muaj kev tsis ncaj ncees hauv qhov chaw ruaj khov, nws tuaj yeem muab tshem tawm thiab rov kho dua. Yog tias tsis muaj teeb meem, lwm cov koob muaj peev xwm tuaj yeem txuas nrog cov cam ntawm cov thawj ncoo ua ntej. Thaum kawg, ntxiv me me ntawm solder rau txhua tus pin raws li xav tau ua kom nws tsau thiab tsis txhob raug tshem tawm. Thaum kawg, siv tweezers kuaj xyuas yog tias muaj cov pins soldered.
