Hi Pete and Dave, I already check with Practical component, Tessera and TopLine Dummy component they said they only have up to 0.5mm pitch CSP. Anyway, thanks for your input... Do both of you know in the market right now is there any 0.4mm pitch C

nope, only placed 0.75mm pitch myself. I looked around some data sheets and did not find any 0.4mm.

We are aware that 0.4mm parts are coming [ http://www.kns.com/prodserv/flipchip/products/roadmap-ultracsp.PDF ], but are assembling none at the present time. We�re in no rush!!!

Hi, We have a customer that want us to produce a single sided 0.4 x 100 x 50 mm size RoHS pcba approx 1000 of them. The board only contains three 2.54mm pitch Non P.I.P, SMT-connectors. We have never produced such a thin pcb:s before. We are thinkin

Hi all, Any stencil opening recommendation for 20mils pitch mirco BGA. Currently, using 12mils round opening, 5 mils thickness. Seen to have weak joints as it crack after Ict testing. thks

Aperture size should vary with the component [pitch]. That size should be the same a the pad size. So, generally pinching is not required. Indium discusses BGA apertures on their site [ http://www.indium.com ]

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.
