Any one using samsung machines, CP40, CP50? I have a 24MM feeder that has 8MM pitch as lowest setting and I need to go to 4MM pitch. Any thoughts as to how I can achieve this? CP40/50 pushers are set for 1 push and higher. Thanks in advance

EIA-481 standard allows the maximum pitch on tape to be 4mm less than the tape width (12mm width and larger). So it is within the standard allowances. As for how common 20mm pitch on 24mm tape is I can not say. I am surprised a 24mm tape feeder ca

We use Samsung and our 24mm feeders have 8,12,16,and 20mm pitch settings. I have found 20mm pitch quite common. My favorite is yhe 12 on 12 our feeders don't support that, we have to put them up on 16mm feeders our cycle them 3 times on a 4mm pitch

I am doing lead free testing on a Vitronics selective machine with a 4 mm nozzle. The finishes I am testing are ENIG, ImSn, and ImAg. The problem I am encountering is achieving good top side wetting. Has anyone had any luck with this type of an ap

Has anyone had issues with their glue stations. After our software upgrades it seems to not be working properly. We have had it slam into the pot, not go into the pot, slam the arm, etc.. Default glue dots used to work now I have to set all their bi

Hi has anyone noticed any issues with reduced component lead diameters on through hole resistors? All the volume manufacturers have or are in the process of reducing the lead diameters from 0.6mm to 0.4mm due to the huge increase in copper prices o

I have seen 0402 inductors that look identical to 0402 caps, come in embossed reels, but the pitch on the tape was 4mm. Im not saying they dont exist, but i have never seen an 0402 component come in an embossed tape with a pitch of 2mm. everything i

A bunch of thanks guys, we will take this in consideration. BTW, we will not go for the v-grove in the panel (2x8 boards + the extra cut of areas). The board house recommended us to go for braces/hinges, since this thin pcb-panel could easily break w

Hello, I havea 0.4mm pitch TQFP with heat transfer pad on the bottom side of component. I will appreciate any suggestions with regards to: 1) stencil thickness (Rest of components on board are 0603 passives and few 40 mil pitch IC's) 2) Stencil

Good morning, Worth system for 0.5mm or more pitch paste printing. For less pitch (uBGA, 0.4mm etc) framed stencil are preferred due to better tensioning. Main issue with them is handling. Stencil apertures that are used for tensioning might be easi
