Ebe ọ bụ na 2014, ngwá electronic ndị na-azụ ahịa, obere ngwaahịa ndị dabeere na ngwaọrụ, ngwaahịa ngwá electronic maka nnukwu ihe mgbochi mgbawa emepụtawo mkpa na-arịwanye elu.Karịsịa, akpakanamde ụlọ ọrụ si eletrọnịkị ina, smt nhazi nke ngwaahịa mụbara budata, ma data nke ụgbọ ala ọhụrụ ike eletriki ụgbọ ele anya ike ibu, eme mkpa mgbawa nhazi nke resistors.
Na mgbakwunye na ndị na-ji ngwá electronic na-eji dị iche iche obere ebe nke ngwa, na mgbakwunye na mgbawa resistors nwere nnukwu arụmọrụ, elu ina, mkpa, miniaturization bụ isi ihe dị mkpa.2018 kacha nta mgbawa resistor size nkenke maka 01005. mgbawa resistors a na-ejikarị, mgbawa inductor na mgbawa capacitors siri ike ịmata ọdịiche dị na ọdịdị.Yabụ kedu ka anyị ga-esi gaa na ndụ anyị kwa ụbọchị iji chọpụta ngwa ngwa mgbawa SMT a na-ejikarị?
I. Ihe dị iche iche nke mgbawa resistors na mgbawa capacitors
Lee anya na agba - niile mgbawa capacitors abụghị silkscreen, elu matting usoro bụ kpodoro isi ala ala okpomọkụ sintering, ọ dịghị ụzọ na-ebipụta na n'èzí.Agba ya na-abụkarị akwụkwọ ndụ akwụkwọ ndụ.
Lee akara - mgbawa capacitors na sekit akara maka "C", mgbawa resistor akara maka "R".
Lee anya silkscreen - e nwere silkscreen na-abụkarị resistor.
II.Chip capacitors na mgbawa inductor iji mata
Lee anya na agba - dị ka ọ na-adị na mbụ, ọ bụrụhaala na gburugburu nke mgbawa tantalum capacitors bụ oji, ọzọ karịa na ọ bụghị oji.Na mgbawa inductor bụ nnọọ oji.
Leba anya na koodu ntinye akara nọmba nlereanya - mgbawa inductor na-amalite na L, mgbawa capacitors na-amalite na C. Site na mmalite nke ọdịdị ahụ bụ gburugburu iji kwubie na kwesịrị ịbụ inductor.
Leba anya na nhazi nke mpụga - ịchọta otu ihe ndị ahụ nwere ike ịbụ ma ọ bụ belata ihe ndị mepere emepe iji hụ nhazi nke mpụga, na nhazi mkpuchi mkpuchi maka mgbawa inductor.
III.mgbawa resistors na mgbawa inductor iji mata
Dabere na ọdịdị - ọdịdị nke inductor nwere ọdịdị polygonal, ebe onye na-emegide ya na-adabere na akụkụ anọ.Karịsịa mgbe gburugburu, dị ka ọ dị na mbụ, ghọtara dị ka onye inductor.
Nyochaa uru nkwụsi ike - uru nkwụsị nke inductor dị ntakịrị, uru nkwụsị nke onye na-eguzogide dị oke.
Zhejiang NeoDen Technology Co., LTD., guzobere na 2010 na 100+ ọrụ & 8000+ Sq.m.ụlọ ọrụ mmepụta ihe nke nnwere onwe ihe onwunwe, iji hụ na njikwa ọkọlọtọ ma nweta mmetụta kachasị akụ na ụba yana ịchekwa ego.
Nwee ụlọ ọrụ igwe nke ya, onye na-agbakọta ọkachamara, onye nyocha na ndị injinia QC, iji hụ na ikike siri ike maka nrụpụta igwe NeoDen, ịdị mma na nnyefe.
Otu R&D dị iche iche 3 nwere ngụkọta ndị injinia R&D ọkachamara 25+, iji hụ na mmepe dị mma na nke dị elu yana ihe ọhụrụ ọhụrụ.
