PCB ink na-ezo aka na ink ejiri na PCB. Ugbu a, ka anyị kerịta gị njirimara na ụdị ink PCB?

1. Njirimara nke ink PCB

1-1. Viscosity na thixotropy
N’ime usoro nhazi nke bọọdụ sekit a na-ebipụta, mbipụta ihuenyo bụ otu n’ime usoro dị mkpa na nke dị mkpa. Iji nweta ikwesị ntụkwasị obi nke mmepụta ihe oyiyi, ink ga-enwe ezigbo viscosity na thixotropy kwesịrị ekwesị.
1-2. Ịdị mma
Nri pigmenti na ihe nchacha ịnweta nke ink PCB siri ike. Mgbe ezi egweri, ha urughuru size adịghị gafere 4/5 microns, na-etolite a homogenized eruba ala n’ụdị siri ike.

2, Ụdị ink PCB

A na-ekekarị ink PCB ụzọ atọ: sekit, ihe mkpuchi solder na ink silkscreen.

2-1. A na-eji ink sekit mee ihe dị ka ihe mgbochi iji gbochie mmebi nke sekit. Ọ na-echebe ahịrị n’oge etching. Ọ bụ n’ozuzu mmiri mmiri photosensitive; Enwere ụdị abụọ: nguzogide corrosion acid na nguzogide corrosion alkali.
2- 2. A na-ese ink na-eguzogide ihe na-ese ihe na sekit mgbe sekit gwụchara dị ka akara nchebe. Enwere foto mmetụta mmiri mmiri, ọgwụgwọ okpomọkụ na ụdị hardening UV. A na-edobe eriri njikọ ahụ na bọọdụ iji kwado ịgbado ọkụ nke akụrụngwa ma rụọ ọrụ nke mkpuchi mkpuchi na mgbochi oxidation.
2-3. A na-eji ink silkscreen akara n’elu osisi, dị ka akara nke components, nke na-abụkarị ọcha.

Na mgbakwunye, e nwere ink ndị ọzọ, dị ka ink nrapado nwere ike ịpụpụ, ink mado ọlaọcha, wdg.
