December 1999 Build of Front and Rear Paddle Boards ------------------------------------------------------- Original Rev. 11-DEC-1999 Latest Rev. 14-DEC-1999 This order will be for the manufacture and assembly of two different types of small paddle circuit boards. These are called the Front Paddle Board (F-PB) and the Rear Paddle Board (R-PB). 15 of the F-PB's are needed and 65 of the R-PB's. The Rear Paddle Board is a 2.9" by 4.95" rectangle with two corners clipped off and is built with a 6 layer process. The Front Paddle Board is a 2.91" by 5.0" rectangle with two corners clipped off and is also built with a 6 layer process. Drawings of these two circuit boards are included. I would like the layup of these boards to be the same as your company used in the fall of 1998 when you make a large number of these paddle boards for us. That layup was described in a 21-Aug-1998 FAX from R.J.Smith and is as follows: Layer 1 --------------------- 1 oz Copper 0.0014" +++++++++++++++++++++ 2313 prepreg 0.0032 +++++++++++++++++++++ 2313 0.0032 Layer 2 --------------------- 1 oz Copper 0.0014 | | | | 0.028 B Stage 0.0280 | | Gnd Layer 3 --------------------- 1 oz Copper 0.0014 +++++++++++++++++++++ 2313 0.0032 +++++++++++++++++++++ 2313 0.0032 Gnd Layer 3 --------------------- 1 oz Copper 0.0014 | | | | 0.028 B Stage 0.0280 | | Layer 4 --------------------- 1 oz Copper 0.0014 +++++++++++++++++++++ 2313 0.0032 +++++++++++++++++++++ 2313 0.0032 Layer 5 --------------------- 1 oz Copper + 0.0014 ---------- Total Thickness 0.085" after plating The assembly of there two cards is described below. The Rear Paddle Board has two types of THD connectors and one type of SMD resistor network. The R-PB's are assembled in 4 different versions depending on whether certain connectors and the resistor networks are installed. The F-PB's has just two types of THD connectors and all are built the same. Assembly of the Rear Paddle Boards R-PB's All 65 of the R_PB's have the 160 pin Female ERNI connector installed at location J1. Then: On 10 of these boards install nothing else besides J1. During assembly the holes at locations J2 through J5 must be kept free of solder. On 15 of these boards, in addition to J1, install the 4 34 pin headers at the locations labeled J2, J3, J4, J5. On 15 of these boards, in addition to J1, install the 8 16 pin SMD 120 Ohm resistor networks at locations labeled R1 through R8. During assembly the holes at locations J2 through J5 must be kept free of solder. On 25 of these boards, in addition to J1, install both the 4 34 pin headers and the 8 16 pin SMD 120 Ohm resistor networks. Components required to assemble the 65 R-PB's. All parts except the raw circuit boards will be supplied by MSU: ITEM Quantity ------------------------------------------------- -------- Raw R-PB circuit board (Hughes manufactured) 65 160 pin Female ERNI Connector #013-167 THD 65 34 pin header 4 wall with latches 90 deg THD 160 16 pin 120 Ohm Resistor Network SMD 320 M2.5x10mm Screw Nut sets for mounting connectors 580 Assembly of the Front Paddle Boards F-PB's All 15 of the F-PB's have the 160 pin Male ERNI connector installed at location J5 and 4 34 pin headers installed at locations J1 through J4. Components required to assemble the 15 F-PB's.

So they only need the Gerber stuff for the Front PB.

W.O. version in the DEC 99 build of R-PB's. On the other hand it is the W.O. W.O. version that can later on be made into anything. xxxxxxxxxxxxxxxxxxxx 14-DEC-1999 Shipment of Parts to Hughes for assembly of F-PB and R-PB ---------------------------------------------------------------------- This shipment contains: Gerber data diskette for the Front Paddle Board. Instructions for manufacture of the Front Paddle Board. A new general description of the assembly of the R-PB and F-PB. Sample R-PB and F-PB assembled circuit boards. Quantity Total in this Quantity ITEM Shipment Required ------------------------------------------------- -------- -------- 160 pin Female ERNI Connector #013-167 THD 66 65 160 pin Male ERNI Connector #004-778 THD 16 15 34 pin header 4 wall with latches 90 deg THD 160 220 16 pin 120 Ohm Resistor Network SMD 0 320 M2.5x10mm Screw Nut sets for mounting connectors 0 730 I have also included a revised description of how we want the boards assembled. The only change is in the R-PB's. We still want a total of 65 R-PB's but we have increased the quantity of one of the types of R-PB by 5 and decreased the quantity of a different type of R-PB by 5. These types of R-PB differ just in which components are installed on the R-PB circuit board. xxxxxxxxxxxxxxxxxxxx 21-DEC-1999 Shipment of Parts to Hughes for assembly of F-PB and R-PB ---------------------------------------------------------------------- This shipment contains: Quantity Quantity Total in this Previous Quantity ITEM Shipment Shipment Required ---------------------------------------------- -------- -------- -------- 160 pin Female ERNI Connector #013-167 THD -0- 66 65 160 pin Male ERNI Connector #004-778 THD -0- 16 15 34 pin header 4 wall with latches 90 deg THD 65 160 220 16 pin 120 Ohm Resistor Network SMD 340 0 320 M2.5x10mm Screw Nut sets for connectors 800 0 730 With this shipment I think that Hughes has all the parts necessary to build the 65 R-PB's and 15 F-PB's. I'm working on getting the Purchase Order to you. It being the holiday season I'm not quite sure when it will get out of MSU and over to you. I will call when I know more. Thanks for working on these boards,
