Te Whakamātau i ngā Pūkeka Whakapā Tirohia i te Whakahaere Mahi Rara

Ka tae ki te mahi i ngā kōmponeta rara, porowhita whakawhetu he tūranga nui kia kitea ai ngā PAP, ā, ka whakamanahia ngā hononga rara. He mea nui te mōhio whānui ki tana tuhinga, ngā momo whakamahi, ā, ngā paihikara hanga hei hanga i ngā hononga whakapā pai me te whakahaere pai.

Whakamāramatanga:

Nā te pūkeka whakapā i hangaia ngā huihuinga matatika e paunga ana i ngā poraka whakapā rara itiiti, ngā mōhu hura, me ngā pūkengenga. Ko tēnei ka āhei ia ki te whakatakoto pai ki runga i ngā taupoka whakapā PAP, ā, e āwhina ana ki te whakapiri i ngā kōmponeta whakatāngata ki runga, me te hanga i ngā ara rara hei whakawāhi i te mahi o te tūroro.

Tongā me ngā Momotu:

I rārangi whānui, he mīhini hāpara tūmuhi e kōwhiri ana i ngā hapa tūmuhi tūmahi (i tēnā i te pewa uku-pūngao rānei nō te SAC305), ngā rauemi pūngao (noke uku-rākau, ka whakarite i te wai, rānei ko te mahere kore-tāwari) me ngā whakapakoko weuweu e āheinga ana i ngā pūtake. E hiki ana te whiriwhiri i ēnei whakamahinga ki ngā hiahia īwa i waenganui i ngā momo tūmuhi, pērā i ngā tohu wehi rūngaro rānei nō te wā.

Whakamahi i roto i te Mahi Whakatupu Rorohiko:

Ki runga i te whenua o te mahi whakatupu rorohiko, ka whakamahi ngā rautaki tuhipōpō rānei ko ngā tūmu whakamahia hei whakatakoto i te mīhini tūmuhi ki ngā paepae tūmuhi rorohiko (PCBs). Mā reira ka tango ngā hanganga SMT ki runga i ngā PCBs i mua i te haere tonu ki runga i te tūmuhi whakamahia i te wā e pūngia ana te mīhini, ka hanga te wehenga kapillari i te wehenga ka puta ai ngā hononga tūmuhi e mau ana i ngā wāhanga katoa.

Nga Tuhinga Ataata:

Kei ngā whakawhitiwhiti hou i ngā pūkeke kaihoko, ko te tūmanako he whakapai i te mahi tuhi, he whakarite i te whanonga o ngā huatau ki te tirohanga kotahi, ā, he whakapai hoki i te tirotiro. E ai ki ēnei, ko ngā whatititi iti ake hei whakatika i te whiuwhiu mō ngā wāhi iti, ko te itinga iti i roto i ngā huatau kaihoro, ā, ko ngā whakahaere e whakaae ana ki ngā hiahia kore-parekura me te pai rawa i te taiao.

Tirohanga me te Whakahaere Pono:

Nā ngā take nui e pā ana ki ngā whakahaere pono i te whakamahi pūkeke kaihoro, ko te whakapai i ngā kōrero stencil; ko te SPI hei whakarite i ngā rahi kawe; ko te tirohanga muri i te reflow hei whakamate i ngā momo hapa, pērā i ngā kaihoro e kitea nei rānei ko ngā kaihoro iti. Nō reira, kei te hīnātupu ēnei mahi hei whakamana i ngā paerewa whakato i te hanga me te tirotiro o te kaihoro.

Ki te whakamutu, he wāhanga nui te pūkeke hē ki ngā mahi whai take moemoeā o te ao ēlekiteretanga i te mea he kōwhiri hei tautoko i te mataara me te haere. Kua hangaia e ia mō ngā momo kawe hē e rerekē ana, ahakoa ko ngā whakapakari i tēnei momo hangarau ka whai tonu hei hīkina i ngā hononga takitahi mō ngā whenua e whakatū ai ngā rīpoata ēlekiteretanga.
