how to mount transistor on heatsink. global trouble doing Delta Pulse.

[Andi68]

This clown simply tears the heatsinks with transistors off the board

What a sucker

[kt315]

wrong placement of the sockets

[kt315]

right position

[kt315]

take the sockets and notice that they easely can be connected together. they have especial groove and ledge for that.

PHILIPPE THIS IS YOUR BOARD AND ALL I WRITE IS RELATED TO YOUR BOARD.

i offer geotechers to find out a problem on the board visually. some kinda exercise for you. (on place of lf357 was tl062 so it is removed)

guys

please do not use this solder. it stretches like a snot. i do not know what it is. lead free solder or what?? DO NOT USE.
very hard to solder and desolder -!!! i WASTE MY TIME ON IDIOTIC JOB -!!!

[kt315]

why you solder with those balls on pins???

[kt315]

PLEASE USE ORDINARY LEAD SOLDER AND ORDINARY COLOPHONY -!!!!

[kt315]

я трачу время на ерунду все заново перепаивая. затем вы просите меня сделать быстрее. почему вы не можете нормально
паять? если не можете то учитесь. этот ваш припой тянется как сопли чинайского дядюшки Лю.

pads of the transistor are torn off http://ipic.su/img/img7/fs/CIMG6451.1550579538.jpg

He's following the amateur's motto: "The bigger the blob, the better the job".

thats sure George. at youtube there are massive amount of videos on soldering matter. with this way they solder
DP board will never work, there will be closed links everywhere.

guys
i do not know how TLC works in DP, i do not have them. thats CMOS type of 556 and needed in additional experiment.
so do not set TLC.
