I am having some diffuculty convincing our exec. staff that by increasing our personel on the floor, we will actually improve our machine efficiency. We currently have seven lines, four of them have two P&P machines in line. At this point there is

Our plan right now is only to increase production on the products that we are behind on. Since we are currently running three shifts with seven assembly lines and only adding six people (3-Days, 3-Nights), it averages out to about a 20% increase ove

according to the ressult of cross-section and removing the component, I find there is no black area in the left pad, and the IMC is also normal, so the black nickle is less impossible. the PCB material is not common FR4, just some thing like ceramic,

We are currently having gross tombstoning with 0402 capacitors. We are using HiPb Solder Paste mounted on Laminate substrates. We are assembling Flip Chip BGA's. Temp @ Reflow is around 230-240 C to meet the thermal requirements for both die bump

Check your land patterns. I believe someone once made a typo on specs for land pattern spacing and the specs are still being used by some people. I worked for a CM that had a customer that spaced the pads for 0402's too far apart. It was the only

The machines you choose depends on the boards you build and how many of them you build. Assembleon is designed for faster production speeds where Juki is more flexible. Why are you just looking at these two? Aren't they in different leagues? Why not

I would look at Universal for sure. They have a ton of late model Chip placer's and GSM's that they will discount heavy. There are so many used GSM's and HSP's on the market you could probably get what you need for a fraction of the cost. You could p

Take a peek at a Samsung CP45v before you make a decision. I'm running two before a CP40v. Runs very well. Clever software. Cheap. I'm also running two Tenryu/i-Pulse FV-7100 in line vintage 1999. Great machines but it may be some time before the sup

Consider slowing down the rate of heating during reflow to eliminate the ejactula. Well, if you feel this is caused by your customer�s design, it is repeatable, you think it�s coming from the reflow process, and you think your reflow process is well
