Why? Just use IPC on finished solder joints as your guide. I've seen groups of people puts hundreds of hours into this task and then tell me a 3 mil stencil is all I need. After reflow, none of the solder joints meet IPC Class 1 and a lot of tombs

The 3000 hours is correct. It was a VERY fast ROI! Back to the discussions on the earlier threads, some of this information is correct. If you exceed the design limitations for keep out requirements and your board tolerances vary, you can have twe

Kelca..... I don't think yer getting the picture here. These boards are supplied by the customer. They are "Labor Only" accounts. We have NO control of the PCB's or any of the parts for that matter. These Labor Only customers show up at the back doo

I have personally worked with MYData, Quad, and Panasonic in the past. We are a High Mix, Low Volume CM. The plan that is in the works is to use the CP6 to place all chip components and then use our MYData TP9 or MY12 to place the rest of the compone

You can spend a couple grand on a manual screen printer, or do what I did back in the day: place the board on the work bench and lay the stencil on the board. If you can hold it steady enough you can use a putty knife to apply your paste. For the s

Back in the mid 90s I used an SVS 3D solder paste inspection system. We used it as a stand along unit but it was an inline model. We would bring printed PCBs off the Dek 265 solder printers and check every 5 or 10 printed panels. They almost alway

Maybe these folk can help you with your MTM issues. http://www.mtm.org We appreciate the desire to balance the line with respect to standard insertion time, number of insertions, and number of assemblers. In reality there are too many variables fo

Dude... That is harsh. I quit the best paying job I had ,at that time, because the owners disrepected me over my deserved salary. I was the sole programmer at this little shop that for some reason lasted for years after I was gone, but anyway....Othe

That's irrelevant to the topic. Incremental technology leaps have occured in everything from automobiles to garden rakes since 1977. But thanks for mentioning Atari as I worked there back in those days. The issue is this: If you took a poll of Amer

I talked to a solder paste chemsist and found out a few things. From above (Dave F) states a test for solder paste involving reflow on a non-wettable surface. Commonly known as the solder ball test this test is performed all the time by paste manufa
