I know that everybody must be tired of people asking for info, manuals or advices, but I do not know other place to ask for help. I need a copy of the first pages (maybe the first 20 pages) of the Juki KE-750 Manual or the Juki KE-700 series manual. If anybody could help me, I will appreciate it. Thanks in advance. Daniel.

Fri, 29 May 2015 07:17:30 GMT Regarding the Footprint designing for Wire bonding technology based Microntroller http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=18111 Hiee everyone, I am a Hardware Engineer and also a PCB designer. I am using a Microntroller which is in "CHIP PACKAGE". So in order to connect our microcontroller with my PCB, i am using "Wire bonding Technology". So, Can any one suggust 1. which type of wire bonding should i use among - Ball Bonding - Wedge Bonding - Compliant Bonding ? SPECIFICATIONS: I. Size of Microntroller - 3.6mm X 3.6mm II. Thickness Of Microcontroller - 200um III. Low Power Application 2. How to design foot print for PCB designing according to choosen wire bonding technology ? Can any suggust a better Websites or Pdf Link's etc.. about wirebonding.

We have a CP45 Neo and it seems that when we exit the program at the end of the day it blows away our last saved .opt file. Has anyone seen this? Here is a description of what I think is happening. 1. 8AM - We do a File-Open of test.pcb from the harddrive. 2. That copy of test.pcb is loaded into memory of the application. (Call this 8am mem copy) 3. We make changes all day, part setup, feeder location changes ect. Doing a File-Save each time to the hard drive back to test.pcb. 4. At the end of the day we shut the machine down & it has a pop up Yes/No box. (Do you want to save?). If we say YES, It appears to not just save the last live copy, but instead pulls teh 8AM mem copy we started with (the last File-Open performed) and copies THAT over our test.pcb blowing away all the changes made during the day. Has anyone else experienced this, or something similar?

Fri, 29 May 2015 04:37:24 GMT Plasma Cleaning System reccomendations http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=18106 I am looking to clean about 50 plastic circuit boards per week with a plasma cleaning system. I am looking at these systems: <a class=roll href="http://www.plasmaetch.com/plasma-cleaning-systems.php" target="_blank">http://www.plasmaetch.com/plasma-cleaning-systems.php </a> Does anyone have a recommendation about size? I don't want to be forced to clean these 4" boards one at a time but I want to watch my budget for this project. I am unsure about future plans for the plasma cleaner.

Right now I am trying to build VisionBot which is a Surface Mount Technology assembly shooter that can be used to place SMD chips onto Printed Circuit Boards for PCBA. Practically the Vision Bot machine will enable electrical engineers, hackers and makers just like me to manufacture electronic devices in their own garage. VisionBot is still in the beta testing and in a few months it will be available to the makers through a crowd-funding platform. Using advanced Computer Vision VisionBot is avoiding electronical waste and is professionally assembling Printed Circuit Boards. It is estimated that VisionBot will be able to assembly about 75,000 electronic boards per year. VisionBot is also compatibile with standardized files like RS-274X Gerber files but works also with the classical CSV files. VisionBot will enable the dream of many makers who want to turn their homemade prototypes into industrial products.

This software is not as refined. The importing function for ODB++ files (typically the best CAD source files for creating programs and documentation) ignores vital elements for complete and accurate documentation, the input parser ignores the graphic outlines of components ( something the previous CircuitCam did well) wonders why they dropped this function. in order to resolve this issue, a painstaking time consuming task of re-drawing the graphics with less that adept graphic tools. There are many deficiencies with this software. Companies looking to acquire this sort of SW should look at Siemens Unicam FX. is a much better tool for creating working assembly documents. Wed, 27 May 2015 15:10:33 GMT Stacking Chip Components http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=18109 I saw a question regarding the acceptability of stacking chip components at this forum posted in 2000. Unfortunately no one could cite any applicable IPC sections at that time. I am now able to find that this is acceptable per IPC-A-610D, Section 8.2.2.9.3 and IPC-A-610E, Section 8.3.2.9. What I still don't know is how many chip capacitors can be stacked - can I stack two components (total of three parts) or only one (total of two parts)? There doesn't seem to be a limitation based of the reference tale 8-2. I would appreciate any insight that anyone can provide.

We are setting up our first SMT line and are looking for recommendations on printers and reflow ovens. Currently most of our manufacturing is outsourced and we want the ability to manufacture all of our products in-house. One important factor is the flexibility to manufacture in smaller batches just-in-time to reduce our finished goods inventory. Sheer volume or speed is not our main concern. We already purchased Juki placement equipment, with enough feeder capacity for a no-changeover setup, as well as a selective solder machine. We also received quotes for a Juki GL printer and RS600 oven (JT), however we are not convinced these are the best choices. Heller was recommended to us as a good reflow oven and we've looked at a Heller 1809 MKIII. For the printer we have less direction but have looked briefly at the Speedline printers. We want decent quality machines that are reliable and easy to use. It is important to maintain a high-level of quality for our finished products while lowering overall operating costs. What reflow oven and stencil printer would you recommend and why?
