Ironwood Electronics
Ironwood Electronics has been the go-to source for advanced adapters, sockets, and modules. Our adapters convert package and pitch between devices, our modules offer complete fully tested assemblies for component replacement and upgrade, and our sockets allow for complete component and assembly testing - from new silicone characterization and validation, all the way thru burn-in and high volume automated testing – always with the highest performance and lowest possible footprint in the industry. Ironwood brings a combined knowledge of hundreds of years of engineering and manufacturing expertise, all under one roof in our state of the art 25,000 sq. foot facility just outside Minneapolis, Minnesota. Combined with our recent acquisition of the Grypper socket line, our continuous new product development demonstrates our on-going commitment to both our customers and the industry we serve.

Probing & Analysis Adapters
-
No matter how well designed a circuit is, there is almost always a need to hook up test instruments to it to verify function, look for bugs, or baseline performance. As IC packages become smaller and pin counts grow this becomes harder and harder. probing adapters are required to alleviate this de-bug problem. Many different types of adapters fall into the test and debug category. The common feature is that they bring the signals of an IC out to a format that is easy to interface with test and analysis equipment.

Grypper "Y"
-
Ironwood Electronics Grypper Y contact is design to work with BGA devices with solder balls/bumps with no equator or small exposure where the standard Grypper cannot reliably hold on to the solder ball. The Y shape, working with the sliding lid, allows reliable contact and ensures device retention in high vibration application. Lower forces, <25 grams, makes insertion easier too and the less aggressive contacting allows 40+ insertions of the same device. The Sliding Lid can be configured to include heat sinking. The Y contact designs cover BGA devices from 0.35mm pitch and larger and the short electrical length has superior electrical performance.

GHz Elastomer Sockets
-
Ironwood’s GHz BGA & QFN/MLF sockets are ideal for prototyping and testing almost any BGA or QFN device application. These ZIF sockets provide excellent signal integrity yet remain cost effective. Innovative elastomer interconnect technology that delivers low signal loss up to >40GHz and supports BGA or QFN/MLF pitches down to 0.3mm was utilized in these sockets. GHz BGA sockets are mechanically mounted over a target system’s BGA lands using mounting and alignment holes at proper locations (page 2 of the individual socket drawing shows recommended PCB layout information). These low-profile sockets are only 2.5 mm per side larger than actual IC packages (industry’s smallest footprint). They support IC devices with body sizes ranging from 55mm down to 1mm. Larger body sizes may require a backing plate. If the backside of the target PCB contains capacitors and resistors, a custom insulation plate with cavities cut for those components can be designed. This insulation plate sandwiches between the backing plate and target PCB.

Socket Accessories (Thru-Hole Options)
-
The male pin adapter consists of standard high temperature FR4 with pressed in terminal pins and threaded inserts for mounting the socket. The top side of adapter has gold plated pads to receive socket interconnect and the bottom side has 0.006″ to 0.018″ diameter pin tails. These pins can be soldered to the plated thru holes in the target board. Then socket can be mounted to the threaded insert.

BGA Sockets
-
Ironwood has the most comprehensive collection of BGA (Ball Grid Array) sockets that can be used for prototype application, silicon validation, system development, thermal characterization, burn-in application, functional production test, etc. BGA socket can be defined as an electromechanical device, which provides removable interface between IC package and system circuit board with minimal effect on signal integrity. BGA sockets for prototype applications, silicon validations, system development applications uses low cost elastomer contact technology.

Stamped Spring Pin Sockets
-
Ironwood Electronics SBT sockets are small footprint sockets that are compatible with other product lines such as GHz elastomer sockets, Giga-Spring sockets, etc. The socket needs about 2.5mm extra space around the chip than the actual chip size utilizing only very small PCB real estate. A heat sink screw on the top provides the compression force as well as thermal relief and can be customized to dissipate more power. SBT socket uses SBT contact technology for high endurance and wide temperature applications. SBT Contact is a stamped contact with outside spring as well as inside leaf spring that provides a robust solution for Burn-in & Test applications. Solutions are available for 0.3mm to 1.27mm LGA, BGA, QFN, QFP, SOIC and other packages. Contact technology has 3 part system which includes top plunger, bottom plunger and a spring. The Beryllium Copper plungers are stamped and assembled to a stainless steel spring in an automated system to enable fast turnaround time, low cost and zero defects.

BGA SMT Adapters
Giga-snaP™
-
Giga-snaP™ 0.75, 0.8, 1.0, and 1.27mm pitch BGA Surface Mount Feet Adapter line of products provide an inexpensive and reliable method for attaching BGA chips to target board. The product line consists of patented female sockets with machined pins epoxy over-molded into an assembly that matches a particular BGA pattern. The epoxy over-molded female BGA socket is soldered to a PCB using standard soldering methods. A corresponding male pin BGA adapter, to which the user attaches their BGA chip, is plugged into the female socket on the board thus interconnecting the chip and the system is ready to go. The SMT adapters have the same solder ball types as the chips they are emulating. These adapters have less than half of the insertion force of competitive adapters, shorter electrical path for highest speed, and can be solder reflowed numerous times. A complete description and drawings of Giga-snaP™ 0.75, 0.8, 1.0, and 1.27mm pitch BGA Surface Mount Feet Adapters can be found at the tables shown below.
