12. Kodi ubwino wogwiritsa ntchito mbale yopera phulusa lachiphalaphala ndi chiyani podziteteza? zoperewera? Yankho: Ubwino: a.Kuphatikizika kwa abrasive pumice powder particles ndi maburashi a nayiloni ndi tangentially kuzitikita ndi nsalu thonje, amene angathe kuchotsa dothi lonse ndi poyera mwatsopano ndi mkuwa woyera;b.Ikhoza kupanga mchenga wonyezimira, wovuta komanso wofanana D. Pamwamba ndi dzenje sizidzawonongeka chifukwa cha kufewetsa kwa burashi ya nayiloni;d.Kusinthasintha kwa burashi yofewa ya nayiloni kumatha kupanga vuto la mbale zosagwirizana chifukwa cha kuvala kwa burashi;e.Popeza mbale pamwamba ndi yunifolomu ndipo popanda grooves, kubalalitsidwa kwa kukhudzana kuwala ndi yafupika, potero kuwongolera kuthetsa kwa kujambula.Zoipa: Zoyipa zake ndikuti ufa wa pumice ndi wosavuta kuwononga zida zamakina, kuwongolera kagawo kakang'ono kagawidwe ka ufa wa pumice ndikuchotsa zotsalira zapopu pamwamba pa gawo lapansi (makamaka m'mabowo). ).
13. Kodi chigawo chopanga komiti yoyang'anira dera chidzakhala chotani kwambiri kapena chochepa kwambiri? Yankho: Nthawi yoyenera yachitukuko imatsimikiziridwa ndi malo otukuka (malo omwe filimu yowuma yosawonekera imachotsedwa pa bolodi losindikizidwa).Mfundo yachitukuko iyenera kusungidwa pamlingo wokhazikika wa kutalika kwa gawo lachitukuko.Ngati malo omwe akutukuka ali pafupi kwambiri ndi kutuluka kwa gawo lomwe likutukuka, filimu yosakanizidwa ndi polymerized sidzatsukidwa mokwanira ndi kupangidwa, ndipo zotsalira zotsutsa zikhoza kukhalabe pamwamba pa bolodi ndikuyambitsa chitukuko chodetsedwa.Ngati malo omwe akukulirakulira ali pafupi kwambiri ndi khomo la gawo lomwe likutukuka, filimu yowuma ya polima imatha kukhazikika ndi Na2C03 ndikukhala yatsitsi chifukwa cholumikizana kwanthawi yayitali ndi yankho lomwe likukula.Nthawi zambiri malo omwe akutukuka amawongoleredwa mkati mwa 40% -60% ya kutalika kwa gawo lomwe likutukuka (35% -55% ya kampani yathu). 14. N’cifukwa ciani tiyenela kukonzekela kale matabwa a zilembozo asanasindikizidwe? Yankho: The pre-ophikidwa bolodi a ndi kupititsa patsogolo kugwirizana mphamvu pakati pa bolodi ndi otchulidwa otchulidwa kusindikizidwa, ndi b kuonjezera kuuma kwa solder chigoba inki pamwamba pa bolodi kupewa solder chigoba mafuta mtanda. -kufalikira chifukwa cha kusindikiza kwa zilembo kapena kukonza kotsatira. 15. N’cifukwa ciani tifunika kugwedeza burashi ya makina ophera mbale asanakonze? Yankho: Pali mtunda wina pakati pa ma pini a burashi.Ngati simugwiritsa ntchito sway pogaya mbale, padzakhala malo ambiri omwe sakhala ovala, zomwe zimapangitsa kuti mbaleyo ikhale yosiyana.Popanda kugwedezeka, groove yowongoka idzapangidwa pamwamba pa mbale.Zimayambitsa kusweka kwa waya, ndipo ndikosavuta kuthyola mabowo ndikutulutsa chodabwitsa popanda kusuntha m'mphepete mwa dzenje. 16. Kodi squeegee imakhudza bwanji kusindikiza? Yankho: Ngodya ya squeegee imayendetsa mwachindunji kuchuluka kwa mafuta, ndipo kufanana kwa tsamba pamwamba kumakhudza mwachindunji khalidwe lapamwamba la kusindikiza. 17. Kodi zotsatira za solder chigoba ndi kutentha ndi chinyezi mu mdima pa kupanga PCB? Yankho: Pamene kutentha ndi chinyezi m'chipinda chamdima ndizokwera kwambiri kapena zotsika kwambiri: 1. Zidzawonjezera zinyalala mumlengalenga, 2. Chochitika chomata filimu ndichosavuta kuwonekera mumayendedwe, 3. N'zosavuta kuyambitsa film to deform, 4. N'zosavuta kuchititsa gulu pamwamba kuti oxidize. 18. Chifukwa chiyani ma solder mask sagwiritsidwa ntchito ngati poyambira? Yankho "Chifukwa pali zinthu zambiri zosinthika mu inki za solder mask. Choyamba, mitundu ya inki imakhala yovuta kwambiri. Makhalidwe a inki iliyonse ndi osiyana. Pakusindikiza, makulidwe a inki iliyonse ya bolodi idzachititsa kuti ikhale yofanana chifukwa cha inkiyi. Kuthamanga, kuthamanga ndi kukhuthala, sizili zofanana ndi filimu yowuma, makulidwe a filimu imodzi ndi ofanana kwambiri, nthawi yomweyo, inki yotsutsana ndi solder imakhudzidwanso ndi nthawi yophika yosiyana, kutentha, ndi mphamvu zowonetsera. Zotsatira za bolodi ndizofanana.Choncho tanthauzo lenileni la chigoba cha solder ngati gawo lachitukuko silili lalikulu.
