I'm a student assistant in a research project that deals with the simulation of PCB assembly systems. At the moment I collect information about SMDs. My problem is how to assign the correct feeder width to various devices in a simulation. Is anybody able to help me ? Thanks Lars Jaeger
I'll give you what our machine feeders measure out to, I use Zevatech machines.
8mm taped components - Mostly passives, from 1005's up to 3216's, SOT's, and mini-melf components. The actual feeder width is 16mm.
12mm taped components - Tantalum C's and larger, the larger ceramic capacitors, larger MELF's, variable caps and resistors, GaAsFET's. The actual feeder width is 24mm.
16mm taped components - Aluminum Electrolytic caps, the smaller IC's SO8's, SO14's, SO16's. The actual feeder width is 32m.
24mm taped components - PLCC20/28's, SO20's
32mm taped components - PLCC32's,PLCC44's, PLCC sockets up to PLCC32 size, SOJ26 (DRAM), TSOP's, BGA (depending on size). The actual feeder width is 41mm.
44mm taped components - PLCC44 sockets, PLCC52's, PLCC68's, some SMT connectors, BGA (depending on size). The actual feeder width is 55mm.
Stick or tube feeders - I use just one size feeder, 44mm wide. I can configure them depending what I want to load. For instance; I can have 4 lanes that will load 4-different SO14's from one feeder, or I can have the feeder configured to load 2-different PLCC28's, or 1-PLCC68.
I hope this helps. Can I ask what your project is? Is it something to do with optimizing machine placement programs? Just curious is all...
