Solder phala kusindikiza njira ya miniaturized zigawo zikuluzikulu 3-3

1) Electroforming stencil

Mfundo yopanga ma stencil electroformed: template yopangidwa ndi electroformed imapangidwa ndi kusindikiza zinthu za photoresist pa mbale yachitsulo yopangira zitsulo, kenako kupyolera mu nkhungu yophimba ndi kukhudzana ndi ultraviolet, ndiyeno template yowonda ndi electroformed mu electroforming madzi.Ndipotu, electroforming ndi yofanana ndi electroplating, kupatula kuti pepala la nickel pambuyo pa electroforming ikhoza kuchotsedwa pansi pa mbale kuti apange stencil.

Stencil ya electroforming ili ndi zizindikiro zotsatirazi: palibe kupanikizika mkati mwa pepala lachitsulo, khoma la dzenje ndi losalala kwambiri, stencil ikhoza kukhala makulidwe aliwonse (mkati mwa 0.2mm, yoyendetsedwa ndi nthawi ya electroforming), choyipa ndi chakuti mtengo wake ndi wapamwamba.Chithunzi chotsatirachi ndi kufanizitsa kwa laser zitsulo mauna ndi electroformed zitsulo mauna khoma.Khoma la dzenje losalala la mesh yachitsulo ya electroformed limakhala ndi zotsatira zabwino zowongolera pambuyo posindikiza, kotero kuti chiŵerengero chotsegulira chikhoza kukhala chotsika ngati 0,5.

2) Stencil ya makwerero

Chitsulo chopondapo chikhoza kukulitsidwa kwanuko kapena kupatulira.Gawo lokhuthala pang'ono limagwiritsidwa ntchito kusindikiza mapepala a solder omwe amafunikira kuchuluka kwa solder phala, ndipo gawo lokhuthala limazindikiridwa ndi electroforming, ndipo mtengo wake ndi wapamwamba.Kupatulira kumatheka ndi etching mankhwala.Gawo lochepetsetsa limagwiritsidwa ntchito kusindikiza mapepala a zigawo za miniaturized, zomwe zimapangitsa kuti mawonekedwe ake azikhala bwino.Ogwiritsa ntchito omwe ali otsika mtengo akulimbikitsidwa kugwiritsa ntchito etching yamankhwala, yomwe ndi yotsika mtengo.

3) Kupaka kwa Nano Ultra

Kupaka kapena kupaka wosanjikiza wa nano ❖ kuyanika pamwamba pa mauna zitsulo, ndi nano ❖ kuyanika kumapangitsa kuti dzenje khoma kuthamangitsa phala solder, kotero demolding zotsatira ndi bwino, ndi kukhazikika kwa voliyumu ya solder phala kusindikiza ndi zogwirizana.Mwa njira iyi, ubwino wa kusindikiza umatsimikiziridwa, ndipo chiwerengero cha kuyeretsa ndi kupukuta zitsulo zazitsulo zingathenso kuchepetsedwa.Pakalipano, njira zambiri zapakhomo zimangogwiritsa ntchito chingwe cha nano-coating, ndipo zotsatira zake zimakhala zofooka pambuyo pa chiwerengero china cha kusindikiza.Pali zokutira za nano zomwe zimayikidwa mwachindunji pazitsulo zachitsulo, zomwe zimakhala ndi zotsatira zabwino komanso zolimba, ndipo ndithudi mtengo wake ndi wapamwamba.

3. Iwiri solder phala akamaumba ndondomeko.

1) Kusindikiza/Kusindikiza

Makina awiri osindikizira amagwiritsidwa ntchito kusindikiza ndi kupanga solder phala.Yoyamba imagwiritsa ntchito stencil wamba kusindikiza mapepala a zigawo zing'onozing'ono ndi phula labwino, ndipo yachiwiri imagwiritsa ntchito stencil ya 3D kapena stencil yosindikizira kusindikiza mapepala a zigawo zazikulu.

Njira imeneyi imafunika makina awiri osindikizira, ndipo mtengo wa stencil nawonso ndi wokwera.Ngati cholembera cha 3D chikugwiritsidwa ntchito, chopukutira chimafunika, chomwe chimawonjezera mtengo wake komanso kupanga bwino kumakhala kotsika.

2) Kusindikiza/kupopera zitini

Chosindikizira choyamba chosindikizira chimasindikiza mapepala ang'onoang'ono, ndipo chosindikizira chachiwiri cha inkjet chimasindikiza mapepala akuluakulu.Mwanjira imeneyi, phala lopangira phala la solder ndilabwino, koma mtengo wake ndi wokwera ndipo magwiridwe ake ndi otsika (malingana ndi kuchuluka kwa zigawo zazikulu).

Ogwiritsa ntchito amatha kusankha kugwiritsa ntchito njira zingapo zomwe zili pamwambazi malinga ndi momwe alili.Pankhani ya mtengo ndi kupanga bwino, kuchepetsa makulidwe a stencil, kugwiritsa ntchito ma stencil ocheperako ofunikira, ndi ma stencil ndi zosankha zoyenera;ogwiritsa omwe ali ndi zotulutsa zochepa, zofunikira zapamwamba kwambiri, komanso ogwiritsa ntchito otsika mtengo angasankhe Pulogalamu yosindikiza / yosindikiza ndege.
