PCB solder chigoba mavuto wamba ndi dera bolodi solder chigoba chophimba makina osindikizira mayankho

The PCB dera bolodi solder chigoba ndondomeko ndi chimodzi mwa maulalo kiyi mu PCB kupanga ndondomeko, ndi nkhani zake khalidwe zimakhudza kwambiri ntchito ndi kudalirika kwa PCB.Mu njira yopangira chigoba cha solder, zovuta zamtundu wamba zimaphatikizapo pores, kutsekemera kwabodza, ndi kutayikira.Mavutowa sangangobweretsa kuchepa kwa magwiridwe antchito a PCB ndi kudalirika, komanso atha kubweretsa zotayika zosafunikira pakupanga.Nkhaniyi adzayambitsa njira zothandiza kuthetsa mavutowa ndi kufufuza ntchito PCB solder chigoba chophimba makina osindikizira pothetsa mavutowa.

1. Kufotokozera za mavuto wamba khalidwe PCB solder chigoba ndondomeko

1. Stomata

Porosity ndi imodzi mwamavuto omwe amapezeka pa PCB solder mask process.Zimayamba makamaka chifukwa cha kutopa kosakwanira kwa gasi mu solder mask zakuthupi.Pores izi zimabweretsa zovuta monga kusagwira bwino ntchito kwamagetsi ndi mabwalo afupiafupi mu PCB pakakonzedwa ndikugwiritsa ntchito.

2. Virtual soldering

Kuwotcherera kumatanthawuza kukhudzana kosauka pakati pa ma PCB ndi zigawo zake, zomwe zimapangitsa kuti magetsi azikhala osasunthika komanso maulendo afupipafupi kapena otseguka.Virtual soldering makamaka amayamba chifukwa chosakwanira kumamatira pakati pa solder chigoba zakuthupi ndi pad kapena zosayenera ndondomeko magawo.

3. Kutayikira

Kutayikira ndi pamene pali kutayikira pakati pa mabwalo osiyanasiyana pa PCB kapena pakati pa dera ndi gawo lokhazikika.Kutayikira sikungokhudza magwiridwe antchito a dera, komanso kungayambitsenso zovuta zachitetezo.Zifukwa kutayikira zingaphatikizepo nkhani khalidwe ndi solder chigoba zipangizo, zosayenera ndondomeko magawo, etc.

2. Yankho

Pofuna kuthana ndi zovuta zomwe zili pamwambazi, njira zotsatirazi zitha kutengedwa:

Kwa vuto la pores, ndondomeko yokutira ya solder kukana zakuthupi akhoza wokometsedwa kuonetsetsa kuti zakuthupi likulowerera kwathunthu pakati pa mizere, ndi ndondomeko Pre-kuwotcha akhoza kuonjezedwa kuti kwathunthu kutulutsa mpweya mu solder kukana zakuthupi.Kuonjezera apo, mukhoza kuwonjezera kusintha kwa scraper pressure pambuyo pa kusindikiza pazenera kuti muthe kuchotsa pores.Apa tikupangira kuti muphunzire za makina ojambulira anzeru okhazikika a solder mask hole okhala ndi makina ake okakamiza.Ndi 6 ~ 8 kg ya gasi, imatha kukwaniritsa The scraper imatha kudzaza dzenje ndi sitiroko imodzi ndikutulutsa kwathunthu mpweya.Palibe chifukwa chokonzanso dzenje la pulagi mobwerezabwereza.Ndiwothandiza, amapulumutsa nthawi ndi mavuto, ndipo amachepetsa kwambiri kuchuluka kwa zinyalala.

Pavuto la soldering pafupifupi, ndondomekoyi ikhoza kukonzedwa kuti iwonetsetse kuti palimodzi pakati pa solder chigoba zakuthupi ndi pad.Panthawi imodzimodziyo, ponena za magawo a ndondomeko, kutentha kwa kuphika ndi kupanikizika kungathe kuwonjezereka moyenera kuti apititse patsogolo kumamatira pakati pa solder kukana zinthu ndi pedi.

Pazovuta za kutayikira, kuwongolera kwamtundu wa solder kukana zida zitha kulimbikitsidwa kuti zitsimikizire kukhazikika kwamagetsi.Panthawi imodzimodziyo, ponena za magawo a ndondomeko, kutentha kwa kuphika ndi nthawi kungawonjezeke moyenerera kuti kulimbitsa mphamvu ya solder kukana, potero kupititsa patsogolo ntchito yotetezera dera.

3. Kugwiritsa ntchito makina osindikizira a Xinjinhui PCB board board solder

Poyankha mavuto pamwamba khalidwe, Xinjinhui PCB solder chigoba angapereke mayankho ogwira.Zipangizozi zimagwiritsa ntchito ukadaulo wapamwamba wosindikizira, womwe umatha kuwongolera kuchuluka kwa zokutira ndi malo a solder chigoba zakuthupi, popewa kuchitika kwa pores ndi kugulitsa zabodza.Panthawi imodzimodziyo, zipangizozi zimakhalanso ndi ntchito yoyendetsera ntchito yanzeru, yomwe imatha kusintha mofulumira manambala azinthu mu 3 mpaka maminiti a 5 popanda kufunikira kwa kusintha kwa gudumu lamanja ndikugwirizanitsa dongosolo lokonzekera bwino kwambiri kuti zitsimikizire kuti kusindikiza chigoba cha solder ndi kolondola komanso kothandiza. .

Yesetsani watsimikizira kuti ntchito Xinjinhui PCB dera bolodi solder chigoba chophimba kusindikiza makina akhoza bwino kusintha khalidwe ndi kupanga dzuwa la ndondomeko PCB solder chigoba.Kugwiritsa ntchito zida izi sikungochepetsa kupanga zinthu zolakwika ndikuwongolera magwiridwe antchito, komanso kupereka makasitomala apamwamba kwambiri a PCB kuti akwaniritse zosowa zosiyanasiyana zofunsira.

4. Mwachidule

Nkhaniyi limafotokoza mavuto wamba khalidwe ndi zothetsera mu PCB solder chigoba ndondomeko, moganizira ntchito Xinjinhui PCB dera bolodi solder chigoba chophimba yosindikiza makina pothetsa mavutowa.Zochita zawonetsa kuti kugwiritsa ntchito solder kukana kumatha kuwongolera bwino komanso kupanga bwino kwa PCB solder kukana njira, kuchepetsa kupezeka kwa zinthu zopanda pake, ndikuwongolera magwiridwe antchito.Pa nthawi yomweyo, zida izi angaperekenso makasitomala ndi apamwamba mankhwala PCB kukwaniritsa zosowa zosiyanasiyana ntchito.Mayankho ndi njira zomwe zafotokozedwa ndi Xin Jinhui m'nkhaniyi zitha kupereka maupangiri ndi chitsogozo chamakampani oyenera.
