Ian, The vision should recognize it; given you've got the correct Part Data. To run 0402 effectively with a CP3 you need: 1. A good, I mean real good, CP4 style feeder for 0402 (1005) 2. 0.7mm nozzles (get from second-source supplier such as WT in

Chris, you are not completely right. Our industrial is following the IPC standard as our guideline. Per IPC J-STD-033 has specify the floor life at para. 8 (normal condition at 30C/60%RH). If Victor can control his environment at 32% then the compo

Mikeal�s approach is one of the more cautious ones. IPC/JEDEC J-STD-033 clause 8.6 talks about 200�C body-temperature not to be exceeded and how it�s best measured. If you go for that method and you made sure that in your wavesoldering (that�s what

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

Hi Edmund, J-STD-013 "IMPLEMENTATION of BALL GRID ARRAY and other HIGH DENSITY TECHNOLOGY" should be a great help for you. Component manufacturers ( try Motorola via Internet) also give good advice. For the DFM aspects get in contact with your asse

Hi, I am in the process of implemeting Through Hole Reflow. 1.I would to know which are the products/Companies that use that use this process. 2. Is there any reference / standard to convince my QA dept. to accept the boards even though there is no

Good point. I'm having trouble with the words "electrical elements" in the J-STD. Is a marking an "element" ?? An upside down chip resistor is certainly not a defect in that it does not negatively impact product functionality or dependability. I sugg

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

I only inhale flux with a high IPA content.(joke for those who don't know me) I have seen the inside of duct work for our wave soldering machine............NASTY! DAVE F. is right! Flux contains a lot of bad stuff- Chlorides, Bromides, Flourides,
