He aha ka Bridging

Hoʻopili ʻana

ʻO ka pilina alahaka kekahi o nā hemahema maʻamau i ka hana SMT.E hana ia i ke kaapuni pōkole ma waena o nā ʻāpana, a pono e hoʻoponopono ʻia i ka wā e hui ai i ka pilina alahaka.Nui nā kumu no ka pili alahaka

1) Nā pilikia maikaʻi o ka paʻi solder

① He kiʻekiʻe ka mea metala i loko o ka paʻi solder, ʻoi aku ka lōʻihi o ka manawa paʻi, maʻalahi ka hoʻonui ʻana i ka ʻike metala, e hopena i ka IC pin bridging;

② He haʻahaʻa ka viscosity o ka paʻi solder a kahe i waho o ka pā solder ma hope o ka hoʻomehana ʻana;

③ He ʻilihune ka hāʻule ʻana o ka hale kiaʻi solder paste, a e kahe ana ma waho o ka pā solder ma hope o ka hoʻomehana ʻana;

Pane: hoʻololi i ka ʻāpana o ka solder paste a i ʻole e hoʻohana i ka paʻi solder kiʻekiʻe.

2) Pūnaehana paʻi

① ʻAʻole maikaʻi ka pololei pinepine o ka mīkini paʻi, a ʻaʻole like ka alignment (ʻaʻole maikaʻi ka hoʻonohonoho ʻana o ka pā hao, ʻaʻole maikaʻi ka PCB alignment), kahi e paʻi ʻia ai ka paʻi solder ma waho o ka pad, ʻoi aku ka maikaʻi o ka pitch QFP pad;

② ʻAʻole i hoʻolālā pololei ʻia ka nui a me ka mānoanoa o ka puka aniani, a ʻaʻole like ka uhi ʻana o ka Sn Pb alloy o ka PCB pad design, e alakaʻi ana i ka paʻi solder nui.

Pane: hoʻoponopono i ka mea paʻi a hoʻomaikaʻi i ka uhi ʻana o ka PCB pad.

3) He kumu maʻamau ia i ka hana ʻana e holo piha ka paʻi solder ma hope o ke kaomi ʻana ma muli o ke kaomi nui.Eia kekahi, inā ʻaʻole lawa ka pololei o ka hoʻokomo ʻana, e hoʻololi nā ʻāpana a e hoʻololi nā pine IC.

4) ʻOi aku ka wikiwiki o ka hoʻomehana ʻana o ka umu reflow, ʻaʻohe manawa o ka solvent i ka solder paste i ka volatilize.

Hoʻoponopono: hoʻoponopono i ke kiʻekiʻe o Z axis o SMT a me ka wikiwiki o ka hoʻomehana ʻana o ka umu reflow.

ʻatikala a me nā kiʻi mai ka pūnaewele, inā he hewa e hoʻopili mua iā mākou e holoi.
Hāʻawi ʻo NeoDen i nā ʻōnaehana laina SMT piha, e komo pū ana i ka umu SMT reflow, ka mīkini hoʻoheheʻe nalu, ka mīkini koho a me ka wahi, ka mīkini paʻi solder, PCB loader, PCB unloader, chip Mounter, SMT AOI mīkini, SMT SPI mīkini, SMT X-Ray mīkini, ʻO nā lako laina hui SMT, nā lako hana PCB SMT ʻāpana ʻāpana, a me nā ʻano mīkini SMT āu e pono ai, e ʻoluʻolu e kelepona mai iā mākou no ka ʻike hou aku:
