Tinyegharịa ovena na-eji na-ere sekit bọọdụ patch components naSMT mmepụta ahịrị.Uru dị n'ime igwe reflow reflow bụ na a na-achịkwa ọnọdụ okpomọkụ n'ụzọ dị mfe, na-ezere oxidation n'oge usoro ịgbado ọkụ, yana ọnụ ahịa nrụpụta na-adịkwa mfe ịchịkwa.E nwere sekit kpo oku n'ime reflow oven, na nitrogen na-ewe iwe na a elu ezuru okpomọkụ wee fụọ na sekit osisi na e mmasị na components, nke mere na solder na n'akụkụ abụọ nke components ga-agbaze na njikọ. motherboard.Gịnị bụ Ọdịdị nke reflow oven?Biko hụ ihe ndị a:
The reflow oven bụ tumadi esịnede nke ikuku eruba usoro, kpo oku usoro, jụrụ usoro, nnyefe usoro, flux mgbake usoro, iyuzucha gas ọgwụgwọ na mgbake ngwaọrụ, okpu ikuku na-ebuli elu ngwaọrụ, iyuzucha ngwaọrụ na ndị ọzọ na owuwu na udi Ọdịdị.
I. Usoro ikuku ikuku nke reflow oven
Ọrụ nke usoro ikuku ikuku bụ arụmọrụ convection dị elu, gụnyere ọsọ, ọsọ, mmiri na permeability.
II.Reflow oven kpo oku usoro
Usoro ikpo ọkụ na-agụnye moto ikuku na-ekpo ọkụ, tube kpo oku, thermocouple, relay steeti siri ike, ngwaọrụ njikwa okpomọkụ na ihe ndị ọzọ.
III.Usoro jụrụ oyi nkereflow oven
Ọrụ nke sistemu jụrụ oyi bụ ime ka PCB dị ọkụ dị jụụ ngwa ngwa.A na-enwekarị ụzọ abụọ: ikuku jụrụ oyi na mmiri jụrụ oyi.
IV.Sistemụ ịnya ụgbọ ala reflow
Usoro nnyefe gụnyere eriri ntupu, ụgbọ okporo ígwè nduzi, nkwado etiti, yinye, moto njem, nhazi obosara nke egwu, usoro njikwa ọsọ njem na akụkụ ndị ọzọ.
V. Flux mgbake usoro maka reflow oven
A na-eji usoro mgbake ikuku na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ, site na onye na-ekpo ọkụ ga-ekpo ọkụ gas na-ekpochapụ ihe karịrị 450 ℃, flux volatiles gasification, na mgbe ahụ, mmiri jụrụ oyi igwe mgbe ikesa site evaporator, flux site elu fan mmịpụta, site na evaporator jụrụ mmiri mmiri eruba na mgbake tank.
VI.Ngwọta gas na-ekpofu ihe na ngwaọrụ mgbake nke oven reflow
Ebumnuche nke ọgwụgwọ gas na-ekpofu ihe na ngwaọrụ mgbake nwere isi ihe atọ: ihe nchebe gburugburu ebe obibi chọrọ, ekwela ka flux na-agbanwe ozugbo n'ime ikuku;Nkwụsi ike na mmiri ozuzo nke gas na-ekpofu ọkụ na ọkụ reflow ga-emetụta ikuku na-ekpo ọkụ ma belata arụmọrụ convection, ya mere ọ dị mkpa ka a na-emegharị ya.Ọ bụrụ na ahọpụtara ọkụ reflow nitrogen, iji chekwaa nitrogen, ọ dị mkpa iji megharịa nitrogen.A ghaghị ịkwado sistemu mgbake gas na-ekpocha ọkụ.
VII.Ngwaọrụ na-ebuli elu ikuku nke igwe nrụgharị n'elu mkpuchi
Enwere ike imeghe mkpuchi elu nke oven reflow reflow n'ozuzu iji kwado ihicha ọkụ reflow reflow.Mgbe efere ahụ dara n'oge a na-arụzi ma ọ bụ mmepụta nke reflow soldering oven, a ga-emeghe mkpuchi elu nke ọkụ reflow reflow.
VIII.Ihe owuwu igwe na-agbagharị agbagharị
Ihe owuwu dị n'èzí na-eji ígwè mpempe akwụkwọ welded.
