Prob totally screwed the pooch... Got more than a little frustrated with not being able to get the stupid software to do what I thought it should do, anyway figured maybe the IEC port was the problem - I have a couple of spare cpu cards, so I swapped

I agree with Joris. But to add to his comment, the type of finish also has a direct affect to your wave solder process. Going from a gloss finish to a matte finish may help a lot. As for humidity affecting your wave - I doubt it. I use a water

I would like to enter the discussion by tossing some numbers in. First of all I don�t like the 3 Sigma value. 3 Sigma are 2000 defects per mio. if I remember correctly. This means, if you have 200 components on the board, then every 10 boards have on

Yeah, perhaps lean more towards a ramp-to-spike profile - reducing the soak time and add a littel heat to your temp above liquid. This has worked for us with water soluable paste as we are not required to use no-clean and utilizing a 6-zone oven. G

I think what Russ is getting at is that the granite table is used for it's flat surface to aid in measurement, the flat surface helps to measure heights very accuratly. If you add another surface on top of that then you lose what the granite surface

Typically - hand soldering as you are currently doing. Should your volume justify it you can invest in a selective soldering solution, these might take the form of a robotic arm that essentially replicates manual soldering or a solder jet similar to

Hi there! If they are just standard headers there's a company called Teka that makes headers and socket headers with solder preforms in them. They call it "Solder Bearing Lead Technology" You can drop them in the board and reflow them just like SMT p

Dave's estimation is pretty conservative but there is a lot of equipment out there and a lot of people happy to make a sale.Implementing both mentioned processes it's difficult and time consuming .Even if you get good training from whoever sells you

Jeff: Try this: ROSA. John�s spot on. I�ll add that it is a fluxless method that reduces the oxides in an aqueous solution. Another source of information is: Trench, M., Hillman, D., Lucey, G., "Environmentally Friendly Closed Loop Soldering,"

Hi Scott, I have worked for a State side PCB Manufacture and now a Taiwan Manufacture. At both shops the up charge was based on how many up the pallet array was plus layer count and complexity of product, charges ranged from free to 15%. Standa
