Manufacturing method for print head

   
   

A manufacturing method for a print head, in which a substrate member provided with heating elements is laminated to a nozzle-formed member in which ink-ejection nozzles are formed, includes the step of laminating a correcting member having approximately the same coefficient of linear expansion as the substrate member to the nozzle-formed member. A nozzle interval L.sub.1 of a nozzle-formed member which doesn't laminate a correcting member at an operating temperature T.sub.0 is determined as =L.sub.2 (1+.alpha..sub.2.DELTA.T)/(1+.alpha..sub.1.DELTA.T), wherein L.sub.2 is the nozzle interval and a heater interval at the operating temperature after the print head is completed; .alpha..sub.1 and is the coefficient of linear expansion of the nozzle-formed member; .alpha..sub.2 is the coefficient of linear expansion of the correcting member; T.sub.1 is the laminating temperature of the nozzle-formed member and the correcting member; and .DELTA.T is the difference between the laminating temperature T.sub.1 and the operating temperature T.sub.0.

Производственный прочесс для головки печати, в которой член субстрата обеспеченный с нагревающими элементами прокатан к сопл-sformirovannomu члену в котором сопла чернил-otstrela сформированы, вклюает шаг прокатывать исправляясь член имея приблизительно такой же коэффициент линейного расширения как член субстрата к сопл-sformirovannomu члену. Интервал L.sub.1 сопла сопл-sformirovannogo члена не прокатывает исправляясь член на рабочей температуре T.sub.0 обусловлен как = L.sub.2 (1+.alpha..sub.2.DELTA.T)/(1+.alpha..sub.1.DELTA.T), при котором L.sub.2 будет интервалом сопла и интервалом подогревателя на рабочей температуре после того как головка печати завершита; alpha..sub.1 и будет коэффициент линейного расширения сопл-sformirovannogo члена; alpha..sub.2 будет коэффициент линейного расширения исправляясь члена; T.sub.1 будет прокатывая температурой сопл-sformirovannogo члена и исправляясь члена; и DELTA.T будет разница между прокатывая температурой T.sub.1 и рабочей температурой T.sub.0.
