как понять что я что-то перегрел? олололово с паяльника наносил. а ты как это делал? транзистор рхх не задевает
контакты в поряде вроде
ну тогда я могу только позавидовать твоей терпеливости. таким образом паять плату - настоящая мука.
припой есть который в мотках продается (тонкий, по толщине как нитка толстая), берешь в одну руку, подносишь, в другой руке чистый паяльник - нагреваешь и все. маленькая капелька отлично фиксирует и аккуратно заполняет отверстия.
в мегамануале технология описана:
To assemble any of these electronic kits, you will need a soldering iron, some solder, and a few other useful accessories. A 15 watt pencil iron will work fine, however a 25 watt iron heats up faster. Get some small solder. For example, you can use 0.75mm resin solder (~0.030") which really helps to put just the right amount of solder in just the right places. You do not need to use silver solder for MegaSquirt. Make sure to let the soldering iron get hot before using it. A hotter tip makes for quicker cleaner joints, and less heat in the components, because the temperature of the lead reaches the melting point of the solder before the component has had much time to heat up (though letting the iron heat for a while also tends to shorten the useful life of the tip). Let it sit 'powered-up' for 10-15 minutes before trying to use it. The solder should melt nearly instantly if touched to the tip.
Never try to paste solder on a joint using excess solder on the tip. Keep the tip clean, and heat the joint (try to get the tip right at the joint between the lead and the PCB) and hold the solder against the other side of the joint until it starts to melt. Feed in just enough solder to get a bit of a cone on the joint, and you are done. Get a solder wick as well - you will be glad you did! It is very useful for removing components. Before plugging in your soldering iron, be sure you read and understand the assembly instructions that follow.
Так что сейчас только проверять всё... на мегамануале есть схемы платы, смотри цепи...
