Fotokozani Mayeso Ouluka pa bolodi mwatsatanetsatane

Mfundo yoyeserera yoyendetsa pini ndiyosavuta. Zimangofunika ma probes awiri kuti musunthire x, y ndi Z kuti muziyesa malekezero awiri a dera lirilonse, chifukwa chake palibe chifukwa chopangira zida zina zokwera mtengo. Komabe, chifukwa cha mayeso omaliza, liwiro loyesa ndilochedwa kwambiri, pafupifupi 10 ~ 40 point / sec, chifukwa chake ndiloyenera kwambiri pazitsanzo ndi kupanga pang’ono; Potengera kuchuluka kwa mayeso, mayeso a singano zouluka atha kugwiritsidwa ntchito kuma board osalimba kwambiri, monga MCM.

Mfundo yoyeserera ya singano zouluka: imagwiritsa ntchito ma probes anayi kuti ayesetse kutulutsa kwamphamvu kwambiri komanso kuyeserera kotsika kotsika (yesani dera lotseguka ndi dera lalifupi la mzere) kwa board board, bola chikalatacho chikhale ndi kasitomala choyambirira komanso pulani yathu yaukadaulo.

Pambuyo pa mayeso, pali zifukwa zinayi zoyendera dera lalifupi:

1. Fayilo yamakasitomala: woyesa akhoza kungofanizira, osasanthula

2. Kupanga mzere wopanga: warpage, solder kukana komanso osakhala ovomerezeka a board ya PCB

3. Kusintha kwadongosolo: kampani yathu imagwiritsa ntchito kuyesa kwaukadaulo waukadaulo, ndipo zina (kudzera) zaukadaulo waumisiri sizimasungidwa

4. Zida pazida: zovuta zamapulogalamu ndi zovuta

Titalandira komiti yomwe idapambana mayeso athu ndikumata, tidakumana ndi kutchinga kwa dzenje. Sindikudziwa chomwe chinayambitsa. Tinaganiza molakwika kuti anali mayeso athu, koma nawonso adatumizidwa. M’malo mwake, pali zifukwa zambiri zotchingira dzenje.

Pali zifukwa zinayi izi:

1. Zofooka zomwe zimachitika pobowola: mbaleyo imapangidwa ndi epoxy resin fiber fiber. Pambuyo pobowola, pamakhala fumbi lotsalira mdzenje, lomwe silitsukidwa, ndipo mkuwa sungayikidwe pambuyo pochiritsa. Nthawi zambiri, timaziyesa mumayeso oyesera singano zouluka.

2. Zofooka zomwe zimadza chifukwa chofunsa mkuwa: nthawi yolowera mkuwa ndi yayifupi kwambiri, dzenje lamkuwa silidzaza, ndipo dzenje lamkuwa silidzaza mukathira malata, zomwe zimabweretsa mavuto. (pokonza mkuwa wamankhwala, pali vuto limodzi lolumikizana ndi guluu wa slag, kuchotsa mafuta amchere, kutulutsa pang’ono, kuyambitsa, kuthamangitsa ndi kusungunula mkuwa, chitukuko chosatha, kutchera kwambiri, ndi yankho lotsalira mdzenje silitsukidwa. Maulalo apadera amafufuzidwa mwatsatanetsatane)

3. Ma viasi a bolodi amafunika zochulukirapo ndipo sanadziwitsidwe pasadakhale zakufunika koboola dzenje. Vutoli limapezeka nthawi zambiri pakakhala kuti nyengoyi ndi yayikulu kwambiri kuti isasungunuke bowo mkuwa ikatha magetsi. Pakadali pano phindu lamalingaliro silofanana ndi momwe ziliri pano, zomwe zimapangitsa kusungunuka kwazitsulo zamkuwa pambuyo pa mphamvu, zomwe zimapangitsa kuti kupitiliza kupitilira, komwe kumaganiziridwa molakwika kuti mayeso sanachitike.

4. Zofooka zomwe zimadza chifukwa chaukadaulo ndi ukadaulo wa tini ya SMT: nthawi yayitali yokhala m’ng’anjo yamatini panthawi yotsekemera imabweretsa kusungunuka kwa mkuwa wa dzenje, komwe kumabweretsa zolakwika. Okwatirana a Novice sakhala olondola pakuweruza zinthu malinga ndi nthawi yolamulira, ndipo amalakwitsa pazinthu zotentha kwambiri, zomwe zimapangitsa kuti nthaka isungunuke. Fakitole wapano wa mbale atha kuyesa mayeso a singano zouluka pamasampuli, ndiye ngati kupangira mbale kukupezabe mayeso oyeserera 100% kupewa mavuto omwe amapezeka m’manja mwa mbaleyo.

Kutsiliza: kudzera pakuphunzira, tidzadziwa zambiri zazing’onozing’ono zakuyesa singano zouluka ndikudziwa komwe tikapite kuntchito yathu.
