Ma mua o ka hoʻokomo ʻana i ka puka aniani solder mask, pono mākou e ʻike i ke ʻano o ka solder mask.ʻO ka mask solder e pili ana i ka ʻāpana o ka papa kaapuni i paʻi ʻia i ka inika, i hoʻohana ʻia e uhi i nā ʻāpana a me ke keleawe e pale aku i nā mea metala ma ka PCB a pale i nā pōkole pōkole.ʻO ka wehe ʻana i ka pale huna solder e pili ana i ka wehe ʻana i kahi puka ma ka ʻāpana solder mask i hiki ke hana ʻia ke kuʻi ʻana ma ka wehe.ʻO kēlā me kēia wahi kahi i paʻi ʻole ʻia ai ka mask solder hiki ke kapa ʻia he wehe pukaaniani.ʻO kahi kahi i paʻi ʻole ʻia ai ka mask solder me nā pad soldered, patch pads, slot positions, a pēlā aku.Aia kekahi hihia i kapa ʻia he puka puka hāmama.ʻO ka puka aniani hāmama, ʻo ia hoʻi, ʻaʻole i uhi ʻia ka ʻaoʻao o ka papa me ka mask solder, a ua uhi ʻia kekahi me ka solder mask.

一.Pehea e hoʻokaʻawale ai "ma ka puka makani" a me "ma ka ʻaila uhi"

Hiki ke lohe pinepine ʻia nā huaʻōlelo "via windowing" a me "via cap oil" ma ka hoʻolālā papa kaapuni.ʻO kaʻoiaʻiʻo,ʻo ia keʻano o ka weheʻana o kekahi i ka puka makani i ka puka, aʻo kekahi e uhi i ka puka me kaʻaila.I nā huaʻōlelo ʻē aʻe, inā e hoʻokaʻawale i ka ʻili o ka PCB..

E wehe ana i ka puka makani'o ia ho'i, hiki ke ho'opa'a 'ia ma kahi i wehe 'ia ai ka puka makani, a 'o ka wehe 'ana i ka puka makani hiki ke ho'okolokolo 'ia e like me ka hiki ke ho'opa'a 'ia.ʻO ka ʻaila uhi e pili ana i ka ʻoiaʻiʻo ʻaʻole maʻalahi ke kī i ka wā o ka patch, i hoʻoholo ʻia e ke kaʻina hana.ʻO nā kumu i manaʻo ai nā vias ʻaʻole lākou i uhi ʻia me ka ʻaila: no ka mea he wai ka ʻaila solder mask a ʻaʻohe ka waena o nā puka via, maʻalahi ka ʻaila e komo i nā puka via i ka wā o ka hana ʻana. ka ʻaila solder mask ma ke apo solder mask.ʻO ka hopena, hiki mai ka melemele o nā vias.ʻO kēia kūlana e pili ana i ka manaʻo o ka solder e kū'ē i kaʻaila, ka umu a me ka ikaika, no laila, aia kekahi mau hihia i hiki keʻikeʻia ka'ōmaʻomaʻo ma luna, aʻo nā mea'ē aʻeʻaʻole hiki.

二. No ke aha mākou e pono ai e wehe i ka puka makani no ka pale pale?

No nā vias, inā ʻaʻole i wehe ʻia ka puka makani, e komo ka ʻīnika o ka mask solder i ka lua.No kekahi mau puka ʻaʻole koi i nā puka ʻīnika, pono e hoʻolālā iā lākou ma o nā puka.No nā mea i kau ʻia ma loko o ka puka, inā ʻaʻole kūʻai ʻia ka PCB e wehe i ka puka makani, ʻaʻole hiki ke kūʻai ʻia nā ʻāpana i ka papa maʻamau.ʻO ka wehe ʻana ʻaʻole wale he hana o ka kuʻi ʻana maʻalahi, akā hiki ke ana ʻia ma vias.Hiki ke hoʻohana ʻia ka wehe ʻana o ka mask solder no nā lua ma kekahi mau kūlana kūikawā e ana i nā vias me kahi multimeter..

No ka PCB, inā ʻaʻole i wehe ʻia ka puka makani, ʻaʻole hiki ke hoʻokō ʻia ka mālama ʻana i ka ʻili, ʻaʻole hiki ke hana ʻia ke kīpī a me ka welding.

三.Pehea e wehe ai i ka puka makani no ka pale pale?

1. Ma ka hoʻolālā, e wehe ka pad i ka puka makani ma ke ʻano maʻamau (OVERRIDE: 0.1016mm), ʻo ia hoʻi, ua ʻike ʻia ka pad i ke keleawe keleawe, a ʻo ka hoʻonui ʻana i waho he 0.1016mm, a ua hoʻopaʻa ʻia ka nalu.ʻAʻole ʻōlelo ʻia nā hoʻololi hoʻolālā e hōʻoia i ka solderability

2. Ma ka maʻamau, e loaʻa i ka puka ma ka puka makani (OVERRIDE: 0.1016mm) i ka hoʻolālā, ʻo ia hoʻi, ʻike ʻia ka puka ma ke keleawe keleawe, ʻo 0.1016mm ka hoʻonui ʻana i waho, a e hoʻohana ʻia ka tin i ka wā o ke kūʻai ʻana i ka nalu.Inā ʻo ka hoʻolālā e pale aku i nā vias mai ka tinning a ʻaʻole e hōʻike i ke keleawe, pono ke nānā ʻia ke koho PENTING i nā waiwai hou o ka SOLDER MASK e pani i ke ala.

3. Eia kekahi, hiki ke hoʻohana ʻia kēia papa no nā wili uila ʻole wale nō, a ʻo ka ʻaila solder mask e wehe i ka puka makani e like me ia.Inā aia ma ka ʻaoʻao keleawe keleawe, hoʻohana ʻia ia e hoʻonui i ka mana overcurrent o ka trace, a hiki ke hoʻopaʻa ʻia i ka wā kūʻai.Inā aia ma luna o kahi ʻano keleawe keleawe ʻole, ua hana maʻamau ia no ka paʻi ʻana i ka pale siliki o nā logos a me nā kiʻi kūikawā, hiki ke mālama i ka hana.
