Thanks for the suggestions, Caurbach. We do have the occasional lead jumping out even at this length, hence why we've been hesitant to cut them shorter. I have the wave nozzle to PCB distance set as per the machine instructions (4mm I think?). I ce

Hi all, Am new to SMT here. I have a very thin laminate substrate which around 120um thickess. Being that thin, warpage is constantly an issue for us. For the solder printing part, we have a number of problems. Being so thin and warped, we need t

Well, the story is a little more complicated. The product is also an LED lamp made on an aluminum PCB with the LEDs on one side and the drivers on the other. The board itself is not big, about 90x90mm and most of the components are soldering well. Us

Hi everyone, I am looking for a distributor for the Folungwin wave machines, we need to buy solder pot heaters part number FL-MD-E-LD-FRG-01 and our canadian distributor only has a few units to sell and the leadtime seems to be around 4 weeks, meanwh

Hi Zac, was that board finished with tin/lead HASL or leadfree/HASL? Also what type of flux were you using? Just because a board is fresh out of sealed packaging doesn't necessarily mean that it's going to solder well. The picture that I've attached

The guys at Honda on the east coast use a potatoe rub. They rub the pot be for solder isadded. Clainm they can reduce drosses that way. Funny how spuds and solder are so close to each other on The Forum here. Prolly explain why they let potatoe f

we do keep out solder paste ready for next shift or for replenish. We specified a location to keep new paste ( only one container ) near stencil machine. As soon as that is use we put another container from freeze, we make sure that at specified loca

The biggest factor is the selective solder machine. Do you want to know the minimum distance that all selective solder machines can handle with no difficulty? If so that will be a fairly large distance. If you are designing for in house boards then y

Hi Does anyone have a tried and tested method of estimating the mass of solder paste that will be used for an SMD assembly given only the type and quantity of components used. (As well as type of paste, stencil thickness etc) In other words is there
