Screen printer, placement machine(s) and oven. You may also need a hand insertion line, selective solder or wave soldr and some form of electrical test. There are a ton of name brands that no two people can agree on. To get a better feel for what

All, I am currently trying to run a quantity of boards thru my wave machine but I am having serious issues with hole-fill or lack of aswell as others. The boards are HASL finish and due to materials issue they have been waiting for Wave Solder Proce

| | | We've recently encountered this problem where one of our .050" pitch BGA's were reflowing at the wave thus causing shorts... The board was profiled with probes stuck to a QFP solder joint, an 0603, and one of the BGA joints. There was an almo

Hi, If your doing a line, then your going to need more than the simple prototyping machines listed above in this thread. (Although they are cool ideas, and loved the toaster oven modification guy, and the other guy soldering ic's with it too!) We a

| | Last week I posted a message on rotary chip waves that stated that the drive shaft had a protective boot around a u-joint that degraded and exposed the joint. | | Someone from the manufacturer read it and contacted me. He told me the problem has

We are going to convert a Leaded Wave machine (EMS Stallion) to Lead Free. Can we just empty the pot of leaded solder, run it with pure tin for a bit and then put in SN100 bar? What's the score with SN100? Oh and does anyone have any paperwork for

1. Is the high RH environment consistently at 72% RH and 21.4 degrees Celsius? No, over the past 2 weeks I have recorded the highest at the moment: 67% RH at 22.6 degrees C and lowest (it is Spring not summer yet): 31.9% RH at 19.0 degrees C. Or d

If you are talking about reflowing surfacemount on the solder side of the assembly, that is accomplished by gluing the smt components to the bottom of the board. I recomend that you use a chip wave in conjuction with the normal wave to get the best r

We're running mixed technology boards with moisture sensitive devices on the top side thru our wave machine. Should I be worrying about "popcorning" these devices if they have been sitting out collecting moisture between the application of SM devices

Watch your dwell time especially if larger components. Problem is normally associated with lower temp as well as insufficient flux coverage with larger massed boards or ground planes. Try to hand spray a board to check that fluxer operation is OK. If
