I am looking for some equipment with a fairly undemanding capability. I would appreciate pointers to potential suppliers. Dispense size 0603 chips only, speed can be as low as 60 chips per minute. Only one type of component (ie one reel) is loaded.

We have some BGA's that don't solder very well. They weren't properly stored in regards to moisture protection. The balls look dull and rough. After reflow there seemed to be a diffinate line between the balls and the solder on the PCB's. I think

Marcos- BGA's and soldering manually is difficult. Typically soldering BGAs requires reflow just as a reflow oven does, so I recommend a rework station. Go to http://www.empf.org/html/empfset.htm and download Jan 2002, Dec 2001, Sep 2001, Aug 2001,

The Alpha metals Hi Check 500 is used to measure paste deposit thickness. The paste height is found from a micrometer reading determined by focussing a beam of light on a track adjacent to a paste deposit and then onto the solder paste. I've measure

We are using 1mm pitch BGAs with a great quantity of via(s) under the component. Very shortly we will be placing CSPs with .65mm pitch. Our via(s) are solder masked, however we generally have a percentage of them that the masking is thin enough that

Dear Tom : I hope I �m not too late. We produce PC motherboards with some buses exceeding the speed of 100MHz . we use no clean flux and it is OK even with the residues you can see under a microscope. But according to our own experience through a mo

I used to build flash memory products for M-Systems. Up to 30,000 per week. Nothing special in the process for these boards. 1mm and 0.4mm thick std. FR4 PCBs are used. Double-Sided reflow. The 0.4mm thin boards require process carriers. Panelized 24

Hello Pete, Very true about the heel fillet. Looks like the pad at pcb has to be designed such that the pad should extend at heel but short at toe. About the encapsulation. I can understand the requirements. Can you provide me with a more detail proc
