We are about to do a second iteration of something we struggled mightily with last time and I'm hoping to at least make a step in the right direction. There are 12 of these parts on the board and virtually all of them required removal and replacemen

Hello, the colleagues are all right. What I did in addition to show customers and quality that we either need or dont need a stencil: 1. Made a procedure - in there i defined 50 000 cycles and then the stencil has to be checked by me. In the checks

I agree with you. I just said, if it is customer requirement, factory has to implement it, right? :) Of course it is huge amount of money. SPI is the main control, but it doesnt save you the pressure, speed, snap of from the printer to the trace (us

Is there a preferred method among printed circuit board assembly for accurately and quickly verifying the copper weight of a printed circuit board? I would like a tool and process that our quality inspector could quickly use to verify upon receipt of

Hi All, Would just like to course through this concern on a product that we are contracted to assemble. It is mainly used for an automatic hand sanitizer dispensing product. By design there is a restrictive value of current that it needs to dissipat

meaning its non-eutectic. You would want to stay as close to 350°C as possible or (if a slightly off version of SAC305) target the highest melting point of your chemistry) - assuming your temp controller is properly calibrated that is. Other option

Hello sir, Limits in SPI can vary a lot, also depending on finishing of the pcb. For example 170% volume on an IC (assuming is fine pitch) can be okay for ENIG, but very bad if HASL. For are I would recommend that you use either 50-130, or 60-135 max

We have 2 Samsung SM482 P&P machines. One we have had for almost 3yrs and the other going on 2yrs. Echoing Spoiltforchoice comments it's critical to use the proper lubricants and cleaners and cleaning/replacing filters when needed. A dusty environmen

We use independant engineers to service our older kit - all with long service careers with the appropriate manufacturers. The manufacturers we deal with tend to have younger engineers who do not know older machines. There are exceptions, in that th

Hi Reckless, If it's a Standard Phillips Sapphire then no, they are not a beginner machine. The feeders have to be spot on and the machine requires a much longer service as they have 2 sets of 12 heads. Spares will start becoming harder to get soon
