Hi Steven, Only assembly is required, we can provide PCBs and parts. The reason why we need them be made in Mexico is because, most of our parts will be shipped from the US, and it only takes 1-3 days from Mexico to the US. Or if there is any US as

Thanks ProcEng1 for the input New, the factory does super deals on feeders as a package. But since I'll only run the machine machine 500 hours per year, we can get a pretty clean used machine 1-3 years old for about 50% of the new money. The lightin

A couple questions for everyone: 1) is there an industry spec that calls out v-score depth requirements? If so, what spec is that and what are the values? I've always heard 1/3 of the depth of the PCB on each side, but I'm not sure if that's a rul

I heard that one can create the stacked/staggered microvias in the layers 1-2 & 2-3 and skip microvia in the layer 1-3 of 6 layer stack up, when the prepreg is between layers 1 & 2 and the other prepreg is between the layers 2 & 3. I want to know w

Great explanation! In my operation I have all tiny chips, 1 SOT223 being largest part but I do have 1 3mm tall inductor which won't work with this machine. Other than 1 part I could run my entire production on it. Also looks perfect for LED produc

You bet our reponse changes. Q2R: Hard gold thickness is 4 to 10 u" for Au and 300 to 400 u" for nickel A2R: This is a hard gold spec?? It looks like a ENIG spec. Although, the Ni is quite heavy, 150 uin is sufficient for most applications. The gol

Hi Adonys, What's ICP 1-3? Do you mean IPC? 1. Excess Plating- no excess, but filled with something which generated in the process of copper plating. 2. Dark Vias - it's oxidized. and the solder mask printing is not aligned. The board is failed. M

Nate, If your stencil vendor has laser-cutting capabilities, they should be able to burn in your fiducial locations. This process involves re-setting the focus of the laser beam to burn the locations 1-3 mils into the surface (as opposed to 1/2 cut

Hi all, At our Fuji CP-6 machines we place a lot of 0402:s, 0603:s and 0805:s chip capacitors. Our problem is that the height of the components can sometime be very extreme from different vendors. I am sure you all have experience of this phenomenon

Dear Folks, could anyone give me an advice who supplies dicing blades (2 or 4") for cutting blended, through hole plated PCBs (1-3 mm thickness). Who has made good experiences (tool life, duration) with which blades? Are there any good application i
