I have a problem with measling on our PCB's. We saw it on our FR4 PCB's at final assembly yesterday. Is this a defect from the board vendor or something we did in our assembly process when building the PCA's (thru hole). Could the wave solder mach

Folks, I 'm in progress of generating the DFM checklist for New Product Introduction on PCA. I need some reference articles to prepare it apart from IPC-SM-782 (surface mont design and land pattern standard)that I'm using now. Any idea of extracti

There is no standard for baking an assembled board prior to BGA rework, nor should there be. The amount of time required to bake a board varies with: * Board material. * Board construction and layers. * Board size. * Components on the board. If som

Paragraph 7.3 of ISO 9000/2000 seems to say that you must have such a process. Developing this process from scratch will be very painful. Consider employing a seasoned veteran. Look here for Earl Moon�s DFM book: http://www.pcbspecialist.com/Epoddfm.

Is there any harm in washing SMT soldered with NoClean paste? The PCA has some large thru-hole connectors that we would prefer to do as water soluble on out selective solder but the SMT consists of LGA's and other low parts that we would not be able

We were using TL1240Y Tack switches for 2 layered PCB and posted those switches by hand. Now planning to re-spin PCA where we recommend that part to be added on SMT process. So looking for a better and opt switch with same specs. Please suggest me an

Good day. I am asking if anyone knows how to access/have a copy of our BIOS file. This BIOS file which was designed by Phoenix , called biosrec.zip. Each day, we used the main EPC-1316(PCA,CPU/PMC)card to boot our Advantis machine; but the speciali

The DEK Gridlock system should have rubber pads on top of the metal posts. We had them in our old Dek machines but upgraded to the fully automatic ones on our O3iX machines (Grid Lok) The manual ones can be tricky to set up and requires you to have
