te kitenga i ngā tākai whakairi e whakamahia ana i roto i te hanga hikohiko

ina tae mai ki te hanga wāhanga hiko,te whakapiriHe taputapu nui tēnei e whakakotahi ana i ngā PCB, e whakarite ana i te pono o ngā hononga hiko. He mea nui te mōhio whānui ki tōna hanganga, ki ngā tikanga tono, ki ngā whakatutukitanga hangarau hoki hei whakatutuki i ngā hononga whakapiri kounga pai me te hanga whai hua.

te whakataki:

Ko ngā whakapiri whakapiri he ranunga matatini kei roto i ngā konumohe, ngā rerenga me ngā rerenga. Ka taea te whakatakoto tika i runga i ngā wāhi whakapiri PCB e āwhina ana i te whakapiri i ngā wāhanga whakapiri mata, e hanga ana i ngā ara hiko e tika ana mō te whakahaere o te pūrere.

te hanganga me ngā momo:

Ko te tikanga, he mea hangai te papanga whakawera taketake ki nga matūriki whakawera whakaranu (i te nuinga o te wa he konumohe-taitai, he raima-kore ranei, penei i te sac305), nga rauemi rere (nga momo raima-a-wai / wairewa-wai / kore-ma) me nga

tono i roto i te hanga hikohiko:

I roto i te ahumahi hanga hiko, whakamahia te tikanga tāngia stencil taputapu tuku ranei ki te tono whakapiri solder ki runga i papa ara iahiko tā (pcbs). i muri i taua e te mata tāpiri hangarau (smt) ngā wāhanga e whakaturia i runga i te pcbs i mua i haere i roto i reflow soldering ka

ngā whanaketanga hangarau:

Ko ngā whakahoutanga i roto i te hoko whakapiri kua arotahi ki te whakapai ake i te āhei tā, te whakarite i te ōrite o te kounga o te hononga, me te whakanui i te pono. Ko ēnei ngā rahi matūriki pai ake mō te rahi ake o te whakaahuatanga i roto i ngā wāhanga iti, te whakaiti i te hauā

te whakahaere me te tirotiro kounga:

Ko ngā wāhi matua e āwangawanga ana mō ngā tikanga whakahaere kounga i te wā e tono ana i ngā whakapiri whakapiri, ko te whakapai ake i ngā hoahoa papanga; te tirotiro mō ngā rōrahi tānga tika; te tirotiro i muri i te rere anō e whai ana ki te kimi i ngā hapa pēnei i ngā piriti i waenganui i ngā whakapiri,

Hei mutunga, he wāhanga nui te whakapiri papu ki ngā tukanga hanga hikohiko hou nā te mea e whai wāhi ana ki te tika me te tere. He mea hanga mō ngā momo tono whakapiri, i te wā e mau tonu ana ngā whanaketanga o tēnei hangarau kia tutuki ai ngā hononga roa-roa puta noa i ngā ahumahi katoa e mahi ana ngā pūrere hikohiko
