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

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

Can anyone point me to a specification or paper describing the existance of voids in transfer mold epoxies during CSP assembly? We have found very small bubbles in our process, but cannot find any information as to whether this is acceptable, and if

I was approached by the comp. suplier to change the capacitors that I currently used. No change in elect. charateristic, but only on : a) change of palladium to nickel base inner electrode b) outer electrode material i.e. from silver to copper. Que

I have an assembly that requires hand solder a part that is in very close proximity to a plastic housed PCI connector. I am using a Metcal iron and am interested if anyone has developed a shroud that will allow soldering in a tight cavity but not me

On the Iron shaft? Why not on the connector to be protected. Actually now that I think back, I seem to remember seeing Kapton tape used on a part in a similar situation, but that I believe was a rework situation. Putting Kapton tape on every assembly

I am looking for a software package that can provide me with a ballpark estimate of labor time required to assemble electro-mechanical products. The inputs that I imagine would include number and size of fasteners, number of wire connections, number

If you want some additional material on 0201 design and assembly the SMART Group Committee produced one of its Charity Reports with all the money raised going to the Red Cross USA September 11th Appeal. You can get it from the SMTA Main office, it fe

It sounds like you already know the answer! How much does it cost you to solder P.T.H. by hand (number of pins/per hour, / cost of assembler) vs. wave preparation and time of loading/masking etc... Cost of rework from each process? Only you can mak
