PCB solder ink mmepe

Iji meziwanye arụmọrụ ịgbado ọkụ ma zere imebi akụkụ ndị na-adịghị mkpa ka welded n’oge mmepụta PCB, akụkụ ndị a kwesịrị iji ink egbochi. Mmepe nke ink PCB nwere njikọ chiri anya na teknụzụ akụrụngwa, ọnọdụ ịgbado ọkụ na chọrọ ahịrị. Na n’ihu PCB njupụta dị elu na ọdịdị nke teknụzụ ịgbado ọkụ na-enweghị ụzọ, a na-etinye ihe ọhụrụ chọrọ maka diluent iji dozie viscosity ink ma mee ka ọ mezuo ihe achọrọ nke ink jet na-ebipụta ink nnyapade solder. PCB solder ink nwere anọ nkebi nke mmepe, site na mmalite akọrọ film ụdị na thermosetting ụdị nwayọọ nwayọọ na-etolite ULTRAVIOLET (UV) ìhè fixation ụdị, wee pụta foto na-emepe emepe solder ink.

1. Ala viscosity nwere ike ịbụ ink-jet ịgbado ọkụ ink

Site na mmepe nke ụlọ ọrụ eletrọnịkị, teknụzụ eletrọnịkị zuru oke na usoro mgbakwunye na-apụta n’oge kwesịrị ekwesị. Usoro mgbakwunye nwere uru nke ịzọpụta ihe, nchekwa gburugburu ebe obibi, usoro dị mfe, wdg N’ihi ojiji nke ibipụta inkjet dị ka ụzọ teknụzụ isi, enwere ihe ọhụrụ achọrọ maka njirimara nke ink na ihe ahụ, ọkachasị gosipụtara dị ka:

(1) jikwaa viscosity ink, iji hụ na enwere ike ịgbasa ya mgbe niile site na nozulu, iji gbochie plọg ahụ izute.

(2) na-achịkwa ọsọ mmeghachi omume ọgwụgwọ, nweta ngwa ngwa mmalite siri ike, gbochie ink na mkpụrụ n’ihi ntinye na gbasaa;

Ink ahụ nwere nkwụsi ike nchekwa dị mma, nwere ike ịgbaze nke ọma na ngwọta sodium carbonate, ngwọta amonia, usoro ihe nkiri na-agwọ ọrịa, thermal, acid na alkali corrosion Njirimara na-ezute ihe ndị dị mkpa.

3. Mmiri-soluble alkali mmepe foto solder ink

Iji belata umu anwuru nke organic solvents na PCB n’ichepụta usoro na ibelata mmetụta nke ihe mgbaze na gburugburu ebe obibi, solder igbochi ink ejiri nwayọọ nwayọọ malite site organic ihe mgbaze mmepe usoro itughari alkaline mmiri mmepe, na na-adịbeghị anya, ọ mepụtara na mmiri. teknụzụ mmepe. N’otu oge ahụ, iji mezuo ihe achọrọ nke teknụzụ ịgbado ọkụ na-enweghị ndu maka ihe nkiri na-eguzogide, meziwanye nguzogide ọrụ okpomọkụ dị elu.

4. Ikanam na elu echiche na-acha ọcha solder ink

TaiyoInk buru ụzọ gosipụta ink ọcha ya na-egbochi ink maka nkwakọ ngwaahịa LED na 2007. E jiri ya tụnyere ink omenala, ink na-acha ọcha kwesịrị iji dozie nsogbu nke ịchacha agba na ịka nká nke na-ebute ogologo oge na isi iyi ọkụ. Omenala epoxy solder ink n’ihi usoro ihe omimi nke nwere mgbanaka benzene, ọkụ na-adị ogologo oge dị mfe ime mgbanwe. Maka isi iyi ọkụ LED, a na-ekpuchi mkpuchi mkpuchi na-eguzogide n’okpuru ihe luminescent, n’ihi ya, ọ dị mkpa iji melite arụmọrụ na-egbuke egbuke nke mkpuchi mkpuchi na-egbuke egbuke na ìhè, wee welie ìhè nke ìhè ọkụ. Nke a na-eweta ihe ịma aka ọhụrụ na nyocha nke ihe ịgbado ọkụ na-eguzogide.
