Pewani kusanganikirana kwa kuwala ndi kuchepetsa chigawo ndi kutsekereza disposal.Monitor otsalira chigawo kuwerengera kupewa utsi wa chigawo chimodzi pa ntchito.

*Chonde tifunseni ma nozzles omwe amathandiza zigawo za LED zamitundu yosiyanasiyana

Ntchito zina

· Ntchito yozindikiritsa zoyipa padziko lonse lapansi Imachepetsa nthawi yoyenda/kuzindikirika kuti muzindikire zoyipa

· PCB standby pakati pa makina (ndi chowonjezera cholumikizira cholumikizidwa)Imachepetsa nthawi yosintha ya PCB (750 mm)

Kupanga kwakukulu - Kumagwiritsa ntchito njira ziwiri zoyikira

Njira Zina, Zodziyimira pawokha & Zophatikiza Zophatikiza

Njira yosankhika ya "Alternate" ndi "Independent" imakupatsani mwayi wogwiritsa ntchito mwayi uliwonse.

Njira ina: Mitu yakutsogolo ndi yakumbuyo imayika ma PCB kutsogolo ndi misewu yakumbuyo mosinthana.

Wodziyimira pawokha: Mutu wakutsogolo umapanga kuyika kwa PCB kutsogolo ndikuyika mutu wakumbuyo ndikuyika kumbuyo.

Kusintha kwadzidzidzi

Munjira yodziyimira pawokha, mutha kusintha njira imodzi pomwe kupanga kukupitilira njira ina. Mutha kusinthanitsa ngolo yodyetsa panthawi yopanga komanso ndi Independent changeover unit (njira).Imathandizira kusintha kwa pini (zosankha) ndi kusintha kosinthika (njira) kuti ipereke kusintha kwabwino kwa mtundu wanu wopanga.

Kusinthana kwa nthawi ya PCB

Awiri PCBs akhoza clamped pa siteji imodzi (PCB kutalika : 350 mm kapena zochepa). Ndipo apamwamba zokolola akhoza anazindikira mwa kuchepetsa PCB kuwombola nthawi.

Kusinthitsa zokha zikhomo zothandizira (njira)

Sinthani kusintha kwa mapini othandizira kuti muthe kusintha kosayimitsa ndikuthandizira kupulumutsa mphamvu zamunthu ndi zolakwika za kachitidwe.

Kusintha kwabwino

Ntchito yolamulira kutalika kwa malo

Kutengera ndi data ya PCB warpage data ndi makulidwe a gawo lililonse lomwe liziyikidwe, kuwongolera kutalika kwa malo kumakonzedwa kuti kukwezedwe bwino.

Kusintha kwa magwiridwe antchito

Malo odyetsa kwaulere

Mkati mwa tebulo lomwelo, zodyetsa zimatha kukhazikitsidwa paliponse.Kugawa kwina komanso kukhazikitsa zodyetsa zatsopano kuti zipangidwe zina zikhoza kuchitika pamene makina akugwira ntchito.

Odyetsa adzafunika kuyika kwa data pa intaneti ndi siteshoni yothandizira (njira).

Kuyang'ana kwa Solder (SPI) ・ Kuwunika kwazinthu (AOI) - Woyang'anira mutu

Kuyendera kwa Solder
