You really must be on a tight budget since most people will pay YOU to take these models off their hands. What is your budget for capital equipment? Zero? That said, I think you would be better served to step up a generation and look at MPA-3's inste

Some other machines are a lot simpler. Here's how the Philips (mady by Yamaha) CSM84 works. Smaller tape (8 and 12 mm) feeders are all mechanical. A plunger on the head pushes a lever on the feeder at the same time the head comes down. First, the

I placed a Maxim MAX16810 38 pin TQFN with a power pad ground on the bottom of the chip on a prototype board FR4 doble sided. Vias of 0.6 mm where placed underneath part, 6 vias in total. Solder was placed with an air operated syringe, land pattern w

Just to add my 2 cents on the adjustment of pitch on MPA feeders: True: Panasonic do not make it easy to change the pitch on MPA feeders, the thickness of a metal part is what sets the pitch. My solution: for example, I get a 24mm X 12mm pitch MPA

Doug, What I've done in past was calling them as 1206T.5, 1206T1.0, SOIC16, RESNET16, SOIC16T5.0, ALCAP4, ALCAP5 etc. T means thickness but for the ALCAP case 4 means 4mm diameter. If you have the time and patience, having a board and attaching a s

Hi! CJ. Please advise what is your pitch size ie 15.7 mil or what is your capabiliy can you build the board with pitch 15.75 mil (please note that the actual dimension of the package is 0.4mm), and how many lead on the package. The pad width of Ind

Dave, Firstly..how the heck are you?..been a while.... Ok so I'm running an Electrovert Electra witha hot gas knife, & I've got large server boards going over the wave. I've seen us loose chip, mainly Tants on the hot gas knife...ain't good especia

Hi Todd, it might be a philosophical question if soldermask between finepitch pads is prefered or not. That should depend on the capabilities of a particular site and their experience. We actually prefer soldermask down to 0,4mm pitch and don�t have

Hey guys, I ran a couple of profile in our wave solder machine using wave optimizer and this is what i got: Parallelism = 0.0 Immersion Depth = 2.1mm to 2.4mm with varying immersion time from 1.1 sec to 3.1 secs. Contact Length = between 5.0 to 6.0

Hi Wolfgang, Thanks for the response. We had a similar situation to yours with some white tin samples that sat around for about eight months. Samples soldered right after they arrived soldered better than the ones we soldered eight months down the
