Round Table Wavelab PCB's

Robin Szemeti - G1YFG
 

If anyone wants Wavelab PCB's  I'll have a stock with me at the round table,   I'll bung some in the bring and buy section with an honesty box, £2 a board.

I'll bring the stencil and paste if people want them pasted with solder,  I would strongly suggest anyone wanting to attempt hand soldering the synth chips has it with paste, it will still be difficult, but it could well be possible.

Hand soldering those multi-legged synth chips without paste is not too difficult.  Place the device very carefully and use a clamp to hold it there - I made one from an old mail sack safety pin.  Flood with liquid flux (I'm sure Kevin will be there) and wipe the joints with a hot iron loaded with solder.  That flux is marvelous stuff.  It almost guarantees no bridges, and if there are any found on subsequent examination, and bit more flux and a ouch with a hot iron and you're done.   I've done many TSSOP and QFP chips like this.   Pad zero, underneath is a bit trickier but it's all described better in   http://www.g4jnt.com/Solving_Pin-Zero.pdf

Paste does make it easier though, place the chips and just stick them under your regular household grill ... or the domestic oven ;) .. you can just place the chip and run a soldering iron down the sides too, that works, but it's not as reliable as just grilling them!  I've had issues in the past trying to hand solder them, even with BGA flux, as always, your mileage may vary.

Soldering the discrete components on a pre-pasted board is a delight though, place in position, gently hold with tip of tweezers on top, apply heat with bare iron to each end .. perfect. Much lower solder levels than using wire solder and a neat appearance. Again, if you are fussy, stick the board under the grill and reflow it ... looks great!
