I am always looking for ways to make my boards more reliable and easier to fabricate and assemble. I have been baselining my footprints off of IPC-7351 and with the latest revision of the calculator they have started a new feature. Normally on say

The pick n place height for component was set to 1.4mm but I had not allowed for pin thickness. I added this (total height now 1.6mm) and I get very few solder bridges now. I might try 1.7 and see if it makes any further differnce

| For space contracts we have to mount chip capacitors/ resistors etc 0.1 to 0.4 mm from the pad height. | | This is to compenstae for the CTE differential in the substrate/component and also to ensure cleanliness. | | Does anyone have any new idea

Hi Indhu, Check for solder paste height. Please manually add solder, mount component and reflow.

Check the dimensions of the components in question with a caliper and put the correct numbers in Your part data. Check that the correct nozzle is being used. Also make sure that you have the right pcb height in Your program. This is somewhat criti

Hi Mike, What type of component you have the problem? For a quick refernce you have two points for the ideal dot: 1- Dot size = 2/3 of area of glue (pad to pad) 2- Dot height = pad thickness + component stand off

Make sure your matrix tray is up high enough. The components in the matrix tray should be at least at board level. Also check your component height in the package list. If all that is OK then, check those Z locks I spoke of earlier.

Have you checked the component height in the package data to ensure that it is the same? how about the PCB itself, could there be some warp or twist thay may cause the component to be dropped onto the board? any support problems? this is all I can

There is a field retrofit to increase the 25mm (0.98425") standard clearance up to 45mm (1.77165"), its not quite the 2", but close. You will have to recreate your component library though. For more details, contact Mirtec tech support at http://www.

You can adjust to 45mm clearance, But I would recommend staying at 25mm if working with fine pitch and smaller passive components.
