SMA Connector to PCB Nkitahodi Akwan
1. Plug Nkitahodi tẽẽ
Pɛpɛɛpɛ Positioning ne Insertion : Fa direct plug SMA plug no ne mounting holes a wɔadi kan -ayɛ wɔ PCB no so no hyia. Fa hyɛ mu brɛoo na fa hyɛ mu brɛoo, na hwɛ hu sɛ plɔg no pin biara ne tokuru a wɔde si so no hyia pɛpɛɛpɛ. Kwati sɛ wode ahoɔden a ɛboro so bedi dwuma bere a wode bɛhyɛ mu no na woakwati sɛ wobɛbɔ plug pin ahorow no anaasɛ wobɛsɛe ntokuru a wɔde si PCB no so no.
Fa Pins no Siesie Yie : Fa tweezers fa ahwɛyiye benkum plug pins no kakra sɛdeɛ ɛbɛyɛ a ɛbɛhyɛ PCB no so yie. Wei hwɛ hu sɛ plug no kɔ so gyina na esiw kankyee biara ano bere a wɔreyɛ soldering, na ɛhwɛ hu sɛ soldering nhyehyɛe a ɛkorɔn-yɛ.
Soldering Pɛpɛɛpɛ : Fa soldering dade no hyew kɔ 300℃-350℃. Fa flux kakra gu contact point a ɛda pin ne PCB no ntam no so. Afei, fa solder wick di dwuma de solder pin no kɔ PCB pad no so. Bere a woreyɛ soldering no, hwɛ bere ne ɔhyew no so yiye, ma pin biara soldering sikɔne 2-3 na amma solder nkwaa a ɛyɛ nwini, circuit tiawa, anaasɛ PCB no asɛe esiane ɔhyew a ɛboro so anaasɛ soldering a ɛkyɛ nti. Sɛ wowie soldering a, fa wire cutters twitwa pin biara a ɛboro so no fɛfɛɛfɛ.
2. Surface Mount Nkitahodi
Preheating ne Soldering: Surface mount SMA connectors hia soldering wɔ reflow fononoo mu. Ɛsɛ sɛ wɔhwɛ ɔhyew a wɔde di kan yɛ no so wɔ digrii 150 ne digrii 200 ntam na ama wɔahwɛ ahu sɛ solder no bɛbɔ koraa na ayɛ nkitahodi pa. Kwati sɛ ɛbɛyɛ hyew dodo bere a woreyɛ soldering no na amma connector anaa PCB no ansɛe.
