Best Technology ndi mmodzi wa opanga bwino pcb ndi kusindikizidwa dera bolodi ogulitsa China
Zikafika popanga ma board osindikizidwa (PCBs) ndi zida zina zamagetsi, njira ziwiri zomwe zimagwiritsidwa ntchito nthawi zambiri ndi ma stencil a laser ndi ma etching stencil. Ngakhale kuti ma stencil onsewa amagwira ntchito yopanga mapangidwe enieni, njira zawo zopangira ndikugwiritsa ntchito zimasiyana kwambiri. M'nkhaniyi, tifotokoza kusiyana pakati pa ma stencil a laser ndi ma etching stencil.
Kodi etching stencil ndi chiyani?
Chemical etching ndi njira yochepetsera yomwe imaphatikizapo kugwiritsa ntchito mankhwala kuti achotse zinthu m'magulu. Amagwiritsidwa ntchito kwambiri popanga mapepala osindikizira (PCBs) ndipo amagwiritsidwanso ntchito popanga ma stencil. Njira yolumikizira ma stencil imaphatikizapo kuyika cholembera pa PCB, kuyeretsa cholembera ndi bolodi, ndikubwereza masitepewa mpaka zomwe mukufuna zitakwaniritsidwa. Kubwerezabwerezaku kumatha kutenga nthawi, ndikupangitsa kuti ikhale imodzi mwazinthu zofunikira kwambiri popanga ma board apadera amagetsi, ma sub-assemblies, ndi ma board board. Kuti athane ndi zovuta zomwe zimagwirizanitsidwa ndi kukokera kwachikhalidwe, opanga ena ayamba kugwiritsa ntchito ma stencil odulidwa ndi laser ngati njira ina.
Chifukwa chiyani mumagwiritsa ntchito etching stencil?
Ma stencil omata ali ndi zinthu zotsatirazi.
l Mtengo wake:
Njira yopangira zolembera zolembera nthawi zambiri imakhala yotsika mtengo poyerekeza ndi ma stencil a laser.
l Kulondola Kokwanira:
Ngakhale kuti sakukwaniritsa mulingo wofanana ndi ma stencil a laser, ma stencil etching amaperekabe kulondola kokwanira pamapulogalamu osiyanasiyana a PCB.
l Kusinthasintha:
Ma stencil a etching amatha kusinthidwa mosavuta kapena kusinthidwa kuti agwirizane ndi masinthidwe apangidwe, kuwapangitsa kukhala oyenera kupanga ma prototyping ndi kupanga pang'ono.
Ma stencil etching nthawi zambiri amagwiritsidwa ntchito muukadaulo wa through-hole technology (THT) ndipo ndi oyenerera pazigawo zomwe zimafunikira ma depositi akuluakulu a solder. Amapeza zoyenera m'mapulogalamu omwe ali ndi kachulukidwe kagawo kakang'ono komwe kutsika mtengo kumakhala kofunikira kwambiri.
Kodi stencil ya Laser ndi chiyani?
Ma stencil a laser, omwe amadziwikanso kuti ma digito, ndi njira yamakono yopangira zinthu zomwe zimagwiritsa ntchito ma laser oyendetsedwa ndi makompyuta kuti azidula bwino zinthu m'mawonekedwe ndi mapatani enaake. Tekinoloje iyi idawonekera m'makampani opanga zinthu kuzungulira 2010-2012, ndikupangitsa kuti ikhale yatsopano pamsika.
Ngakhale ndi chitukuko chaposachedwa, ma stencil a laser amapereka maubwino angapo kuposa ma stencil achikhalidwe achikhalidwe. Opanga amatha kupindula ndi kuchepa kwa nthawi ndi zofunikira zakuthupi popanga ma stencil pogwiritsa ntchito njirayi. Kuphatikiza apo, ma stencil odulidwa a laser amapereka kulondola kowonjezereka poyerekeza ndi ma etching awo amankhwala.
Ubwino wogwiritsa ntchito laser stencil
Ma stencil a laser ali ndi zizindikiro zotsatirazi.
l Precision Yachitsanzo
Kugwiritsa ntchito ukadaulo wa laser kudula kumathandizira kupanga mapangidwe ovuta komanso oyengedwa, kuwonetsetsa kulondola kwambiri pakuyika kwa solder pa PCBs.
l Kusinthasintha
Ma stencil a laser amapereka makonda osavuta komanso osintha kuti akwaniritse zofunikira pakupanga, kuwapangitsa kukhala oyenera pamitundu ingapo ya mapulogalamu a PCB.
l Kukhalitsa
Ma stencil awa amapangidwa makamaka kuchokera ku chitsulo chosapanga dzimbiri chapamwamba kwambiri, zomwe zimawapangitsa kuti azikhala olimba komanso kuti azikhala ndi moyo wautali, motero amalola kugwiritsidwa ntchito kangapo.
Ma stencil a laser amapeza kugwiritsa ntchito kwambiri njira zaukadaulo wapamtunda (SMT), pomwe kuyika kolondola kwa solder paste kumagwira ntchito yofunika kwambiri. Kugwiritsa ntchito kwawo ndikopindulitsa makamaka kwa ma PCB olimba kwambiri, zida zomveka bwino, komanso kuzungulira kwapang'onopang'ono.
Kusiyana pakati pa etching stencil ndi laser stencil
Kusiyanitsa pakati pa ma stencil a laser ndi ma stencil etching zitha kufotokozedwa mwachidule motere:
1. Njira Yopangira:
Ma stencil a laser amapangidwa kudzera mu kudula kwa laser, pomwe ma etching stencil amakwaniritsidwa pogwiritsa ntchito etching yamankhwala.
2. Kulondola:
Ma stencil a laser amapereka mwatsatanetsatane kwambiri, osachepera ndi 0.01mm, kuwapangitsa kukhala abwino kwa zigawo zomveka bwino komanso ma PCB olimba kwambiri. Mosiyana ndi izi, zolembera zolembera zimapereka kulondola kokwanira kwa mapulogalamu omwe ali ndi zofunikira zochepa.
3. Zakuthupi ndi Kukhalitsa:
Ma stencil a laser amapangidwa makamaka kuchokera kuzitsulo zosapanga dzimbiri, zomwe zimatsimikizira kulimba kwa ntchito zingapo. Mosiyana ndi zimenezi, zolembera zolembera zimapangidwa makamaka kuchokera ku mkuwa kapena faifi tambala, zomwe sizingakhale ndi mulingo wokhazikika womwewo.
4. Mapulogalamu:
Ma stencil a laser amapambana munjira za SMT zomwe zimaphatikizapo kuzungulira movutikira, pomwe ma stencil amapeza kugwiritsidwa ntchito kwakukulu munjira za THT ndi mapulogalamu omwe amafunikira ma depositi akuluakulu a solder.
Kusankha pakati pa ma stencil a laser ndi ma etching stencil pamapeto pake kumatengera zosowa za PCB yopanga. Mapulojekiti omwe amafunikira kulondola kwambiri, zida zomveka bwino, komanso kuzungulira kwazungulira angapindule ndikugwiritsa ntchito ma stencil a laser. Mosiyana ndi izi, ngati kukwera mtengo, kusinthasintha, komanso kugwirizana ndi ma depositi okulirapo a solder amatenga patsogolo, ma stencil etching amapereka yankho lothandiza.
