I am optimizing a stencil opening for BGA with 0.4mm pitch and pad diameter of 0.2mm. Can anyone advice of stencil thickness and stencil opening I can use in order to have a good paste release. Thanks for all your answers.

We decided to bake components in tray package at 70 Degree prior soldering. I am looking for suggestion regarding baking time for MSL3 components: Up to 1.4mm package thickness 1.4-2 mm thickness 2-4.5 mm thickness In JEDEC-033B this temperature is n

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

6 mil (0.15mm) for the 1.13mm pitch BGA, and 4 mil (0.1mm) for the smal QFN with 0.4mm pitch.

I would look at the Samsung CP40 or 45. They have the placement rates you want even a little better on the 40. the 45 will double that easily. They handle all types of parts down to 0201 components. Depending on the camera you select (25mm) you ca

Yes, using an illuminated magnifing glass helps. How well your board fixuring is on the table will effect print alignment on other boards loaded. 0.5mm & 0.4mm will require very good fixuring, like you can get with tooling pins if the board has non-p

I've searched the archives and maybe my search skills aren't up to snuff but I couldn't find much. I'm curious what people are doing for 0.4 mm pitch BGAs, assuming a type 4 paste. Pad diameter? SMD or NSMD? Stencil thickness? Aperture diameter? Us

Our company is going to attempt to place 0201 components using our Fuji CP4-3 with the upgraded SMD3 vision system. Count On Tools is providing the 0.4 mm nozzles and we are using our 8mmX2mm feeders with the 0.7mm tape leaf (if it works at all we w

Size is 21mm (relaxed) x 4mm (OD) x 0.25mm wire... Manufacturer is Flexo Springs But for an in stock item that costs not much more than $1... I would think hardly worth the time and effort to have one made.
