SERVICE, QUALITY & INNOVATION
MPT supplies thick film microcircuits, from printing thick film substrates, complete assembly, to functional and environmental testing. Thick film capabilities include multilayer of conductors, line/spacing up to 1-2 mils, via through and via filled. Laser trimming capabilities: kerf width .001 - .003", 0.1% tolerance, 50 ppm measuring accuracy and 4 ppm ratio. MPT has clean areas of class 1000 for pre-cap inspection and class 100,000 for assembly. For commercial application, MPT has developed 1-2 mils Ag conductor line/spacing on thick film technology to replace thin film substrates. This new process reduces cost substantially for MPT’s commercial product line. MPT has implemented automated assembly processes for die mounting and wire bonding, as well as computerizing and automating many functional tests.
MPT has recently developed a series of RF modules for cellular communication and
personal communication service (PCS); more precisely, control components of feed forward
amplifiers used in base stations. MPT’s VA (Vector Attenuator), APS (Attenuator-Phase
Shifter combined) and LNA (Low Noise Amplifier) have been accepted enthusiastically by
designers of feed forward amplifiers in PCS industries. All of MPT’s RF modules are
surfaced-mount devices, using innovated thick film process and automated assembly line
procedures to enhance competition with commercial products. Even though these products are
for commercial application only, they are manufactured under facility and processes
qualified for MIL-PRF-38534 and certified to ISO9001; screened and tested per MIL-STD-883
with selective testing as follows:
- Internal visual inspection
Destruct bond pull test (3 pcs/lot)
Stabilization bake
Bubble detection
Constant acceleration (if necessary)
Temp cycling test (0° C to 70° C; 3 pcs/lot)
Pre-seal and final electrical testing
The hard-core of MPT’s quality assurance system is always MIL-PRF-38534, regardless of its commercial or industrial products. MPT is committed to excellent quality, customer service, product and process innovation. MPT provides quick turn-around for prototypes and just-in-time for production.
