Makhalidwe

Timayesa zoyenerera za ngongole za ogulitsa, kuti tiwone khalidweli kuyambira pachiyambi. Tili ndi timu yathu ya QC, tikhoza kuyang'anira ndi kuyang'anira khalidweli panthawi yonseyi kuphatikizapo kubwera, kusungirako, ndi kubereka. Zonsezi zisanayambe kutumizidwa zidzasankhidwa ku Dipatimenti yathu ya QC, timapereka chitsimikizo cha chaka chimodzi ku mbali zonse zomwe tapereka.

Kuyesedwa kwathu ndi:

Kuwunika Kwambiri

Kugwiritsa ntchito microscope stereoscopic, maonekedwe a zigawo zikuluzikulu za maonekedwe a 360 ° lonse. Cholinga cha malo owonetsera ndikuphatikizapo mankhwala; mtundu wa chip, date, batch; kusindikizidwa ndi ma phukusi; pepala lokonzekera, coplanar ndi kukwera kwa mlandu ndi zina zotero.
Kuyang'anitsitsa maso kumatha kumvetsetsa mwamsanga chofunikira chotsatira zofunikira za kunja kwa opanga mtundu wa mtundu, zotsutsana ndi static ndi miyezo ya chinyezi, ndizogwiritsidwa ntchito kapena kukonzedwanso.

Ntchito Kuyesedwa

Zochita zonse ndi magawo omwe amayesedwa, amatchulidwa monga kuyesa kwathunthu, malingana ndi zolemba zoyambirira, zolemba zolembera, kapena tsamba lothandizira makasitomala, ntchito zowonongeka, kuphatikizapo madera a testamento, koma sizinaphatikizepo zizindikiro za AC kusanthula ndi kuonetsetsa gawo la mayeso osadziwika kwambiri malire a magawo.

X Ray

Kuunika kwa X-ray, kuyendayenda kwa zigawo zikuluzikulu zokwana 360 ° kuzungulira lonse, kuti mudziwe momwe zimakhalira pansi pa mayesero ndi phukusi logwirizanitsa pathupi, mukhoza kuona zitsanzo zambiri pansi pa mayesero ali ofanana, kapena osakaniza (Zosakanikirana) mavuto amayamba; Kuphatikiza apo iwo ali ndi ndondomeko (Datasheet) wina ndi mzake kusiyana ndi kumvetsa kulondola kwa chitsanzo poyesedwa. Kugwirizana kwa mgwirizano wa phukusi, kuti mudziwe za chip ndi phukusi loyanjanitsa pakati pa mapepala ndilochilendo, kuchotsa makiyi ndi makina otseguka.

Kuyesedwa kwa Solderability

Iyi si njira yowonetsera yonyenga pamene okosijeni amapezeka mwachibadwa; Komabe, izi ndizofunika kwambiri kuti zithe kugwira ntchito ndipo makamaka zimakhala zowonjezereka m'madera otentha ndi amvula monga Southeast Asia ndi madera akumwera ku North America. Mgwirizano wofanana J-STD-002 umatanthawuza njira zoyesera ndikuvomereza / kukana njira zazitali, mapiri, ndi zipangizo za BGA. Kwa zipangizo zopanda pamwamba pa BGA, kuzungulira-ndi-kuyang'ana kumagwiritsidwa ntchito ndi "testamentiti ya ceramic test" kwa zipangizo za BGA zakhala zikuphatikizidwa muzinthu zina zamtumiki. Zipangizo zomwe zimaperekedwa pakapaka zosayenera, zikwama zovomerezeka koma zoposa chaka chimodzi, kapena zimawonetsa zowonongeka pamapini akulimbikitsidwa kuti ayesedwe.

Kusintha kwa Kufufuza kwa Imfa

Mayeso owononga omwe amachotsa zinthu zosungunula za chigawochi kuti awulule akufa. Imfa imafufuzidwa chifukwa cha zolemba ndi zomangamanga kuti zidziwe tsatanetsatane ndi chidziwitso cha chipangizochi. Mphamvu yamakono yokwana 1,000x ndi yofunikira kuti muzindikire kufa ndi zolakwika zakufa.
