does anyone know where used matrix trays could be purchased? Topline wants a ridiculous amount for them. Need to handle parts 16.2mm x 12.3mm x 2.31mm. REceived in T&R but need trays to bake out and then place.

We are currently having a conflict of opinion with our QA department regarding the very few occurences we have of chip resistors being soldered upside down (i.e. the resistive element towards the board). IPC-A-610C para 12.3.2 specifies that this co

Placing a component the correct side up: * May affect heat dissipation. [Umm, that sounds like stretch, but who knows what designers think about?] * Allows reading the markings on those components that have markings, however cryptic the notation of

Marcel, Reconfiguring your machine from 80 to 20 stations is quite easy. In the sequencer portion of your machine, it has it's own I/O box. in it, there's the MIT card, location (1). The bit switches are there to inform the controller in the in

Startup current depends on your configuration. ours dose zones 1,2/ 3,4/ 5/ 6,7 last i checked it pulled about 40-55 ish on start up and 25-35 during run. our profile is a slow ramp till 170c then a fast ramp to 285c 280c(last 2 zones). 1707's

Takt time (without a google search) is the rate (amount of time per pc.) at which stuff gets made on an assembly line, a workcell, a hi-speed SMT line, CNC machine cell, etc.... Takt time is governed by the gate (the slowest person, machine, etc. in

In a similar conversation ... Alex Krstic, NovAtel Inc. said ... Hello all. We recently received some boards with some of the chip resistors placed with their resistive elements towards the board. J-STD-001B and C view this as violation for both Cl

RS, It seems you've been doing your homework. However, the real question is what do you need to do with AOI? 1) What is your minimum cycle time? This would help you to determine the speed you need and whether "scan on the fly" is warranted. Also,
