MPLAB(R) ICE 2000/4000 Transition Socket Specification INTRODUCTION Transition sockets are devices that allow MPLAB(R) ICE WHAT TRANSITION SOCKETS ARE CURRENTLY AVAILABLE? 2000 and MPLAB ICE 4000 device adapters to interface to sockets on customer products that differ from the standard emulator adapter connection. Microchip Technology currently offers the transition sockets listed in the Table of Contents following this introductory section. Embedded microcontrollers/microprocessors come in many different types of IC packages, (i.e., DIP, PLCC, SOIC, SSOP, MQFP, etc.). Typically, development cycle components are EPROM based and, as a result, are provided in larger windowed package formats such as DIP or PLCC. Production components are primarily preprogrammed ROM, OTP or Flash-based and are often in very compact SOIC, SSOP, MQFP or PQFP package formats. The Product Line Card (DS00148) lists the transition sockets available for each device adapter of the MPLAB ICE 2000 or 4000 System. For more on MPLAB ICE 2000 device adapters, see the MPLAB ICE 2000 Processor Module and Device Adapter Specification (DS51140). For more on MPLAB ICE 4000 device adapters, see the MPLAB ICE 4000 Processor Module and Device Adapter Specification (DS51298). The MPLAB ICE solution is transition sockets. A transition socket is specifically designed to provide compatibility between two differing types of IC package formats. Please check the Microchip web site (www.microchip.com) for the most current version of all documents. Transition sockets are typically composed of two parts: the DIP adapter socket and the SOIC/SSOP header. The DIP adapter socket is designed to plug into the emulator system's DIP device adapter on one side and the header on the other. The header is then soldered down to the target application. The QFP Adapter is a single part soldered directly to the target application and fits into the QFP device adapter. WHY SHOULD I USE TRANSITION SOCKETS IN MY PRODUCT DESIGN? HOW CAN I OBTAIN MAXIMUM BENEFIT FROM THE USE OF TRANSITION SOCKETS? Attention to component placement should be considered to provide adequate clearance for the transition socket interface to the PCB footprint. This is especially true for any tall components such as connector headers, radial components or voltage regulators. Refer to the transition socket mechanical drawings for dimensions. There are two very significant advantages to using transition sockets: 1. 2. Shorter product development cycle. Reduced expense in the design, layout and prototype testing. A typical product design cycle has two important phases: the prototype design phase and the production design phase. Traditionally, these phases were different simply because the prototype used a microcontroller with a different package type. However, with the availability of the transition sockets, the prototype design can be identical to the production design because a transition socket can be used to bridge the microcontroller package differences. 2004 Microchip Technology Inc. DS51194K-page 1 MPLAB(R) ICE 2000/4000 TRANSITION SOCKET APPLICATIONS - COMMENTS AND SUGGESTIONS Attention to component placement should be considered in mating the adapter sockets to the SOIC/SSOP headers. If visual alignment is difficult in your application, C-shaped end brackets have been included to aid in header-to-adapter socket alignment. Clip the brackets onto the SOIC/SSOP header. The placement of via's around the Surface Mount Technology (SMT) layout area should be examined. Via's immediately adjacent to the end of a SMT pad may inadvertently come into contact with the header leads. Via's should be placed along the centerline of the SMT pad to lessen the chance of pin-to-pin shorts while soldering. The SOIC header is designed for SOIC body width of 0.300-inch, the adapter leads should be cut to fit the 0.150-inch and 0.208-inch SOIC body widths. For information on packaging dimensions, please refer to DS00049.

TQFP TRANSITION SOCKET SOLDERING TIPS * Before soldering, consider keeping the break away tabs in place during soldering. * Use controlled soldering iron tip temperatures between 300C and 325C (570F to 615F) * If possible, use a PACE mini wave soldering iron tip or an equivalent tip design. * Plan to solder one (1 of 4) side first, then the opposite side, then remaining two sides. * Soldering iron tip movement should be in direction of the leads (backward and forward), not across the leads; dragging the tip across the leads may cause lead damage. * Use generous amounts of soldering flux to aid in the solder flow action. * If the breakaway tabs are removed after soldering (using a dental pick or equivalent), any solder bridging between leads can be repaired by simply gently touching the soldering tip to the lead tip. CAUTION The 64- and 80-pin TQFP headers are very delicate and can be easily damaged!

See the drawings in this section for layout dimensions. 2004 Microchip Technology Inc. DS51194K-page 15 MPLAB(R) ICE 2000/4000 For transition sockets that use a cable, follow these instructions for installing your transition socket on the target board. PCB Layout Considerations: Make sure you leave enough room on the PCB to accomodate the cable, i.e., space your target pads for each device far enough apart so that the cable from one pad group will not interfere with another pad group. 8-Pin DFN Assembly Instructions: 1. 2. 3. 4. 28/44-Pin QFN Solder Instructions: 1. 2. 6-Pin SOT Solder Instructions: 1. 2. 3. 4. Remove protective cable covering from end of cable. Position cables on target board (see below.) Tape down to prevent movement. Solder each lead to target pad. Remove tape and clean. Start with cable associated with pin 1. Fold cable up and over, forming a radius. Mate with the header on the side of the transition socket assembly, making sure pin 1 mates with the pin labeled "DFN Pin 1". Fold over and mate the other cable. 3. 4. 5. Remove protective cable jacket from stripped end of cable. Lay out with long cables opposing each other and short cables opposing each other (see below.) Place center lead (6th lead for 44-pin, 4th lead for 28-pin) on center target pad to center each cable on the footprint (see below.) Tape down each cable to prevent movement. Solder each lead to target pad. Remove tape and clean pin 1 long RECOMMENDED INSTALLATION OF TRANSITION SOCKETS WITH CABLES pin 1 8-Pin DFN Solder Instructions: 1. 2. 3. 4. Prepare leads by trimming narrowest portion to 0.10 inches maximum in length (see below.) Position cables on target board (see below.) Tape down to prevent movement. Solder each lead to target pad. Remove tape and clean. header pins facing down 28/44-Pin QFN Assembly Instructions: 1. 2. 3. trim leads short long short use center lead to center cable on target footprint 4. Start with cable associated with pin 1. Fold cable up and over, forming a radius. Header pins will now be facing upwards. Mate with the socket on the underside of the transition socket assembly, making sure pin 1 mates with the pin labeled "QFN Pin 1". Fold over and mate the other cables. pin 1 DS51194K-page 16 2004 Microchip Technology Inc.
