Do you have influence on the design process ? Avoid components you are not able to assemble in certain $-limits. A way to put delicate parts on the pcb that your P�n�P isn�t able to place is to add an SMD-manipulator used for manual assembly between

Chris, one question, which standard allows to put it in the drawings/dokumention? As I said in my old IPC-D-275 it says "no". Did it change with the new edition ? Referring to J-STD-001 in this case seems to me like "I followed only the orders and do

Yeah, 0201's are real buggers to deal with, as the components are about the same dimensions as the PWB tolerances. Probably a good start is the paper I did with Plexus Corp., available on www.plexus.com, under the "In the News" heading. Headlines: -

The SMT LAB at Universal Instruments Corp. has presented a paper entitled "Process parameters optimization for mass reflow of 02\01 components" at APEX 2000. If you weren't able to attend, an excerpt is available at www.UIC.com, under the AUTOMATION

Boca- I can enlighten you on the dental floss thing, but first you must provide a $40 bill to satisfy the insatiable Humm sisters. Beyond that, you gotta raise some bees, grab some trusty zircon encrusted tweezers (any self respecting SMTer would onl

Charles, I think the misplacement can be devided into 2 groups: 1. parts misplaced by machine 2. parts move as the X-Y table moves If you use the solder paster right, and the place force is properly setup, the second group will be definitely no exce

Peter: This isn't what you asked for (I think), but it may be neater. Source of SMT links (jumpers): Most resistor suppliers make zero ohm resistors. Size � 8mm - 10mm (.312in -.4in) long: Most resistor suppliers package these resistors in comm

John - CK can probably help you further once you answer those questions, but for now what's your top side temp and how are you applying flux? Two of the primary causes for bridging are conveyor instability (vibration) and turbulance in the solder wa

I was running the conveyor at 3.75 when we started the discussion with Electrovert. Unfortunately, foam fluxing is a fact of life for us. Our products have open contact relays that can become contaminated by spray fluxing. Titration is our only me
