Jun 13, 2005 | Hi All, There are IPC drafts in circulation IPC-1751, Generic Requirements for Declaration Process Management and IPC-1752, Materials Declaration Management. To me it looks like the regulations become more tolerable towards lead in solder Lead in solder would make the boards still compliant under

Apr 3, 2002 | Hi Guys, We have a customer who is requesting us to issue a document ECN (engineering change notification) record to them, IF we have any changes in : 1) direct materials used, 2) indirect materials used, 3) machine configuration, 4) change in SMT Line we run the product, 5) process flow changes : the customer has declared failure to notify them of any ECN change whatever so within 30-days advancement, will result in the customer possible exercise of their "right" to reject all Lots run under the period of time, that they were not "in the light" with regards to our "unauthorized" ECN changes... Anyone

Apr 21, 2005 | that out right declare it. For example, some old JEDEC Standards for ICs dictate inches, but newer ones for ICs, BGA and such clearly state only millimeters in the specifications (and don't even offer inch equivalents). 0603 (metric) is 0.6 X 0.3 millimeters and that converts to 0.024 x 0.012 inches

Jan 25, 2006 | I agree Rob, The main thing is that you don't beleive everything without question. If you're sure the supplier knows what he's doing and you have a good relationship with him then a declaration should be OK. When doubt arises it is worth getting samples analysed. An XRF is a good piece

Sep 13, 2000 | PCB Material My question is concerning a cheap PCB material. I have a sample with me and I have to quote on this product with the same PCB material. This material is not FR4 and the color is beige. I think CEM-1 material is beige too but I`m not sure. I`ve heard about a material called `` bakelite ``( I `m not sure of the spelling ). I did try to get information from PCB company from North east of USA, Canada and China and they don`t know about this product. What I want to know is : When you want to use a cheap material, what are you using ??? Bakelite, CEM... I need help about this Thank you Francois
Oct 29, 2004 | Electrochemical migration under conformal coating: That's possible. Very few conformal coatings are water resistant. So, if you have ionic material on your board, standback. Uncured material under several IC: Materials like yours need moisture from the atmosphere to cure. So, when the material at the edges of the IC cure, the material under the IC virtually stops curing. It can take weeks for it to cure. Recognize that toluene is a mild health hazard.
Jun 6, 2009 | Alternative PCB Material If the concern is the increased moisture absorption associated with lead-free capable materials, you probably have the most experience with phenolic materials like Isola IS410 or 370HR. The best move would be to switch to an IPC 4101/99 or /124 material like FR406HR. We've tested these to have moisture absorption rates of less than 0.1%, as opposed to up to .45% seen in phenolic materials.
Jun 25, 2009 | In the life of this product that you have been doing this process, has the material alway's been IT180 material? One problem with Lead free material is that it is more fragile that standard FR4 Epoxy laminate. And is known to have chipping or fracture issues due to the ceramic like nature of the material. Couple things to check: What pre-preg was used? example 7628 1 ply pre-preg or 1 ply? This could be more than a Board shop issue, Root problem could be product design, material selection, tolerance issue due to over or undersized hole verse tolerance issue on pem, pre-preg material past shelf life, poor temp control in pre-preg inventory room. Have your board supplier send you the material stack up used for the product, check this against customer Print to make sure correct stack up was used. Have them get Material supplier involved and have them check lot codes of material to make sure
