Siteshoni Soldering ndi manja awo

Pa kukonzetsa Chip, mavabodi, kompyuta n'kofunika kugwiritsa ntchito chitsulo soldering. Koma si nthawi zonse yabwino ntchito, chifukwa mofulumira overheats, palibe kuthekera kusintha kutentha. Ndiyeno muyenera mafoni patsogolo siteshoni rework. wakumbatila wake anaphunzira kulenga amisiri.

mwina - kupanga siteshoni soldering kuti aikidwa mu magetsi (yeniyeni, thupi lake) ndi soldering, pa kukula kwa makumi asanu ndi atatu kuti millimeters makumi asanu ndi limodzi mphambu makumi asanu, sipangakhalenso chikugwirizana thereto EPSN akale. Kulenga siteshoni soldering chofunika kukhala ndi kukana kuti soldering chotenthetsera resistive sensa ndi zina mphero mbola 1.6 millimeters.

Mu EPSN ophatikizidwa thermocouple multimeter ku China. Mtsogoleri gulu akhoza kupeza kukula ndi makumi atatu kwa millimeters makumi atatu. Zam'manja digito siteshoni soldering, ndi manja awo anasonkhana, inati wokonzeka kugwiritsa ntchito soldering zolemba kangoloko. Pambuyo Launch Mtsogoleri zikuphatikizapo ACC ndi akuwerenga zolowetsa pa PC0, PC1 voteji mlingo. Zikatero, ngati ali ofanana ndi ntchito yobweretsa voteji, choncho palibe soldering, ndipo pali mawu «mumalakwitsa», cholakwa Akuti ikusonyezedwa.

Pamene voteji mmodzi wa zolowetsa ake ndi zosakwana 4.5 volts, ndiye n'zotheka kusankha soldering chitsulo kapena resistive kapena thermocouple. Komanso, aliyense akhoza kugwiritsa ntchito mabatani kusintha kutentha. Chionetsero zikusonyeza kuphethira dontho kuti limatiuza zimene zipangizo amusankha. Mphamvu soldering chitsulo akhoza lizilamuliridwa ndi PWM kusinthasintha mawu VT1 kiyi.

Pamene tikupita siteshoni soldering ndi manja awo, mungachite popanda transistors owonjezera, chifukwa pa panopa 2 MA ndi atalandirapo kwambiri ndi kuwala. Cathodes mwachindunji chikugwirizana ndi madoko Mtsogoleri. LED mawaya woonda ayenera solder bolodi ndi kukonza mbali kumbuyo mwa zomatira otentha Sungunulani.

Kuti akomere ndi mabatani ndipo anasonyeza ayenera kupanga maenje mu gulu kutsogolo. Chithunzi pane mu galasi chifanizo zimasindikizidwa mandala film, woyera phala-kumbali zomatira tepi kuchokera chitsanzo tona kudula padziko wozungulira ndiyeno glued nyumba ya. Pakuti mayiko mabatani bwino n'kudziphatika kwa gulu njira zomatira otentha Sungunulani.

Ntchito unsembe, ndalama zambiri, monga mavabodi kapena PC laputopu, oyenera infuraredi siteshoni soldering, ndi manja awo kuti izo, nawonso, si weniweni. Pakuti soldering pamwamba-wokwera kusindikizidwa dera bolodi ndi zigawo zake (mwachitsanzo, BGA) kupsa kapena mpweya otentha kapena cheza infuraredi.

chipangizo ndizo gulu kulamulira ili ndi nyumba zosiyana. Iwo ali heaters awiri ndi mindandanda yamasewera chifukwa matabwa. Udindo wa chapamwamba zikhoza kusintha malinga amalipiritsa lokhazikika. Pansi chotenthetsera amapereka kutentha mchitidwe kwa magetsi mphamvu mu kilowatts awiri ndi awiri a millimeters mazana awiri ndi makumi awiri. Upper chotenthetsera - anayi tubular halogen nyali. Aliyense wa iwo - 150 Watts. Choncho, siteshoni soldering, ndi manja awo pamodzi, umakhala yomalizidwa tione.

miyendo itatu A chingapangidwe kuchokera ku n'kupanga chosindikizira masanjidwewo. The zina mwa mfundo - komanso anaitenga ku zida akale kompyuta. Chizindikiro akutumikira ziwiri mzere madzi galasi gawo ndi Mtsogoleri. M'malo zimachitika tiransifoma bwino ntchito semistors ndi radiators. Kumbukirani kuti zikundithandiza pa unsembe ayenera kusamala monga semistors. Kuwonjezera zigawo zikuluzikulu zofunika chofunika kwa magetsi siteshoni soldering kuti lili panopa kupyolera mu njira ziwiri, kiyibodi, kuwonetsera, buzzer ndi chowunikira ziro.

Ngati munalenga siteshoni soldering ndi manja awo, ndipo ndikofunika kudziwa zina mwa malamulo pa ntchito ndi chitetezo chake. Mwachitsanzo, tisalole halogen nyali anali wodetsedwa ndi mafuta. Choncho, iwo ayenera mosamala kutsukidwa ndi kafungo kabwino kapena mafuta, musanayambe kuvala magalasi oteteza.
