First seen during the apprenticeship period, the repair of my masters at a different soldering technique on a two-piece aluminum grease thoroughly with a soldering iron back and forth as excavations made by continuous solder soldering soldering of aluminum have kept going after some effort
Our workshops are a lot of us were pretty rich there were strange material handling equipment including grease and the occasional odd jobs to do, but would be fitting cut mechanical works etc..
This method years later, in rare cases of mine worked for me, I’m fat instead of solder paste I use (lötfett) is important to be soldered surfaces of the air disconnect to inhibit oxidation for that matter a lot is available and soldering iron you how powerful the better results you will get 30. 40w soldering iron with a very hard, maybe too small thin pieces can be soldered
more professional method
Aluminium on the grease is driven below the oil with a knife scratches taken a two scratches would be enough fat layer air passage for blocking scratches with exposed in the interior oxide layer does not occur after the oil-coated surface iron and molten recine is dropped fat layer evaporates and surface resin coated staying Switching to the soldering process after at least a 100 watt soldering iron should be used

TAS5630B 300W Class D Amplifier Circuit TAS5630B 300W Class D Amplifier Circuit The core of the whole amplifier circuit is the TAS5630B one connection is based on modified the recommended BTL mode stereo input, which is listed by the manufacturer in Selection of the final chip involvement consisted of four different modes, of the optional input pins M1 to M3: TAS5630B 2 x BTL – two separate channels (full bridge connection, power up to 2x300W) TAS5630B 1 x PBTL – the only channel in bridging (parallel output up to 1x400W) TAS5630B 4 x – four separate channels (performance 4x145W to 2? Or 4x75W into 4?) TAS5630B 1 x BTL + 2 x SE – two channels involved in half the bridge (SE) and one channel to full bridge (BTL), suitable, for example, for 2.1 speakers. Selected was mode 2 x BTL, I mean the classic stereo modes, TAS5630B from which it can be seen that the input the signal is transferred to the pins of INPUT_A to D, which then goes into the filter slucky. In this block processes the input signal together with the signal from the feedback then progressing through the analog multiplexer to the analog comparator, where PWM modulation occurs by comparing the input signal and the signal from the oscillator, which is known from the theory of the D-class block of the PWM receiver Process the PWM signal and oversees its parameters through the feedback of the slug through the detector the activities of PWM.
