We don't like ministencils. Consider using the patterns listed in the Practical Components and Topline catalogs. Few BGA we see have a 3X3 courtyard.

You're correct. This design will have a record amount of 0402 rework for tombstoning and misalignments. Suggest that the pads on each end of all components be the same size in order to balance wetting forces during reflow.

Has anyone had issues with Renco inductors failing. The component I'm having problems with is a 330uH shielded power inductor. Out of 36 board failures, I have 17 that failed because this inductor failed. Most often they end up reading -1.34 uH.

Steve: Try to find something that�s common to all your skewed parts. We haven�t had much trouble with it except for some MELF diodes a couple of years ago which didn�t look well aligned but made no trouble with specs. Better suited pad design solved

I prefer mine skewered with a remoulade, yum. IPC-A-610 allows component side overhang to the lesser of either up to 25% of the component termination width or up to 25% of the width of the pad for Class 3 devices. Help us understand your problem.

You might want to look at pin in paste. It is not very common but I have seen it work very well.

We are recieving BOM from our customers.Certain customer's BOM will not specify the complete details in the description Column (Like Package,tolerace, voltage limits etc).They will be specifying the MFR's PArt # only. Is there any common website avai

I have never heard of heating boards prior to v-score. Have you established any trends on component orientation and cracking? What is your v-score thickness range? Do you have your blades regularly sharpened? Have you measured your blade alignment?

To my knowledge, the 40C was established as the maximum "safe temperature" for all tape and reel packaging. The actual specs may vary somewhat for different types of reel, pocket-tape, cover-tape but you must be concerned with the cover tape adhesive

Simulating with what? In developed countries manual labour is expensive but is also still the most common solution to fitting though hole parts, even if the board are then wave-soldered. Mixing SMT and THT on what sounds like a very simple product wi
