I have recently purchased a datapaq 9000 and need to create an ISO document to use this device in my process. I will be using it for profiling new jobs for SMT and TH as well as monitoring the consistency of the oven performance. Before I create this

Try looking at your reflow profile. If he slope is too steep you may get solder balls. I've had the same problem, had to slow down the profile a bit. If you'd like, there was discution on wave soldering chart.. and Speedline one hase some points f

Just setting up a new SMT line and have questions on which profiling product to use. So far the two in consideration are Super M.O.L.E. Gold and Slim KIC 2000... Please share any thoughts, experiences you have had with either and your opinion....

Grant, The board maybe the problem but how is your oven working? Is it a convection oven and how many zones (top and bottom)? What does your profile look like? If you are unsure and if you only have one oven, send your board to Soltec or Electrovert

I would suggest scoring if the profile allows, leaving residual material of circa 40 - 50 mil - That is what I do on a 125mil thick PCB width of the pis is approx 200 mil Mouse bites on a board as thick as 135 mil will mean its extremly difficult to

Good Afternoon, We have found that the occurance of tombstones is usually related to other parameters. Board design, placement accuracy, paste tack time and thermal profile are the most common. We do use a 2% silver paste to process 0201 components

Hi Yes I agree, yet this subject is about Tombstoning and oven profile or even oven working correctly across the entire product is a sub-set of how one gets those little chip babies to sit and stay where they belong. Flat and Heeling like their mast

Hi, We are placing (+) & (-) terminals in SMT. We have just changed the plating of them: from Nickel to Tin (Sn). During the trial, we used the same reflow profile as before changing, and the solder seems different: a bit cold, with some solder paste

Frank, ECD (WaveRIDER) and Datapaq (Optimiser) have wave solder machine process control devices. They will check the following: 1. Conveyor speed 2. Preheat Temps 3. Solder Temps 4. Wave Dwell/Contact Times 5. Wave Heights 6. Waves Parallelism Go

We have a line that is double sided reflow and reflow/wave depending on the product being manufactured. We asked Loctite if we could cure our chipbonders with the reflow profile to eliminate having to change oven profiles for each. They said we wou
